What I hate is the infuriating ones where you click a correct box, and it slowly disappears to be replaced with ANOTHER picture, which is probably also a fire hydrant, so you have to click that, too.
my guess is it's probably to avoid bots who are like insta-clicking the pictures and so the captcha is like "hey I didn't get time to load this next image, wth thats too fast". but idk /shrug
@@microman502 pick the image of the eldritch nightmare standing at the end of your 2nd floor hallway that is currently waiting for you recognize its presence.
I was once given a captcha that asked to select the images of parking meters. One of the images was a plastic mailbox that the captcha thought was a meter. I failed the captcha for knowing it wasn’t a meter.
These capture images go to computers worldwide, American mailbox's can look very similar to parking meters in the UK and other countries around the world and the ai learning will be messed up by this. And tbh, as a Brit, I originally thought those type of mailboxes were just a 'Hollywood movie' thing and didn't actually exist in real life (they do!). Cus why would anyone want potentially important letters placed in an easy to steal from box at the edge of the road... Just get a letterbox and have them pushed through your door directly into your houses. 🤣
@@Ryukai-san Unfortunately the United States is very large and there are many zip codes that mail needs to cover daily, and also people like to build houses separated from the road so letterboxes aren't thus fashionable. (Never lived in a city so I'm not sure about that, but I think for more cramped spaces in the US people either have a kind of have a wall/room of mail for their entire apartment/building where they go down to the desk and pickup their items (possibly get notified when some come in) or they have P.O. boxes) Tangentially related: my current belief as to why some things are like that in the UK is that the UK has been built up through literal centuries and therefore has housing (and other) conventions that last past their age, as opposed to the US where there's so much land people can kinda "waste" or "recycle" land on the newer conventions
@@richardpike8748 Also it probably has something to do with the fact that Americans seem to think they need a car to travel a few hundred metres. Hell the amount of times while I have been there I have simply walked to the destination and been there waiting for them to arrive when we left at the same time is silly. Over distances that short the time taken to get into a car is a significant portion of the time needed to simply walk.
@@Ryukai-san Security might also play a role here. Here in Venezuela we have so little security that we don't trust some random getting close to our doors to leave the mail behind, instead we prefer to get from a little distance away from our front door.

The best captcha is the one that records the imperfect nature of our physicality. Our hand forced to helplessly drag a mouse with all the meandering. It knows that bots are the only beings capable of moving from a to b in a perfect straight line since it's not bounded by our anti perfectionist universe.
"Let's stop AI by making them read and at the same time train an AI to learn how to read" "We no longer can use that anymore as somehow AI's have learned how to read"
And once the AI could read and the captcha was useless, they said "Lets use object recognition as a test. And feed the data to our object recognition AI."
In my opinion the most elegant one is the one where you simply click the "I'm not a robot" checkbox and all the analysis/evaluation is done behind the curtains.
Elegant and insidious. Elegant because it steals your habits without you realizing and insidious because those digital habits can be used for anything from placing ads where you can't ignore them to allowing hackers to bypass gateways by scripting mouse movements instead of other code more likely to be identified as a virus.
That's good because if filling out the form normally takes a human many seconds, a bot can't log into many sites per hour and the poor bot will get frustrated.
@@bob456fk6 -- Or you just run multiple instances of the bot set to type at human speed, using randomized variables to delay mouse movements and mimic human types of behavior, even occasionally making intentional "mistakes" to appear more human. People who code bots often have access to web logs and can see how real traffic behaves and, since the whole point of making a bot is to get money, they will implement those features.
Just gonna drop my favorite quote which I always get reminded of when CAPTCHAs come up: "There is a considerable overlap between the intelligence of the smartest bears and the dumbest tourists." -Yosemite Park Ranger on why it's hard to design a bear-proof garbage can.

My favorite kind of Captcha is the one where you click the verify button and then just wait for a few seconds and then the Captcha is just done with no effort whatsoever.
it uses browser fingerprinting and analysing your mouse movements on the way to the checkbox, maybe checking cookies and whatnot too. if you use a privacy-first browser you'll probably never get just the checkbox and it will move on to having you solve a problem
Right now I'm regularly having to deal with a "choose the similar shapes" captcha. Problem is that I'm color blind, and the red-on-purple hexagons and green-on-yellow triangles are almost impossible for me to pick out. Especially given the teeny-tiny window it gives you.
@@Supreme_Lobster Not so easy to fake if some ML classification model is used. Human inputs are imprecise with some patterns, not totally random noise.
The problem with this one is that it assumes a stereotypical Hollywood AI which operates on total logic and zero cultural awareness. That's not how AI turned out to be in reality at all. An actual AI would easily choose the second option because it has seen that specific combination of text far more frequently in its training.
fun fact: on some sus websites (pirated movies and stuff), if you're shown a captcha it might not be for the site you're on, instead it's getting you to solve it for a different site so it can bot *that* site don't need to make the AI better if you can just get a human to do it without knowing 😌
I remember this old audio test that still scares me to this day, it was one where you type the characters you hear but the audio sounded like a loud intercom in a parking lot with sirens on in the background, very unsettling

You might be interested in Chinese CAPCHA too, they have evolved to rely on different uses of the Chinese language. For example: 1. As Chinese characters are basically square-y pictures, like 架, 奇, 雯 etc., they ask you to rotate a random character upright in the correct way. People who knows Chinese can do that effortlessly. 2. Different Chinese characters have the same or similar pronunciation, e.g. 忍, 人, 認, 刃, 仁, 韌, 飪... are all "ren" in mandarin, spoken in different tones, and all commonly used. So there is a CAPCHA for you to pick "which word sounds the closest to the given word". And also, to match the word to the given pinyin (i.e. "ren") and vice versa. 3. Three random, uncommon Chinese characters are given, and the distorted version on these three characters are hidden in a colourful picture. You are asked to click on each, according to the order they are listed in the question.
In order to get a Japanese google account, I had to answer a captcha with distorted Japanese text. Certain characters in Japanese are difficult to distinguish even when not distorted. Guess which characters they used!
The one’s I’ve encountered ask you to click on four characters part of an idiom (成语) in the order they appear in that idiom. They’re usually rotated and on some kind of background, as per usual captcha tests. Sometimes I have to pull out my dictionary if I don’t recognize the idiom 😂
At this point, we've gone from "how do we fool an AI that can't recognize text if it's a picture" to "how long before AIs learn how to recognize, behave in response to, and interpret abstract concepts better than humans?"
I think it was never about "How can we fool it" and always about "How long does it take until it's better than us". That's more often than not the reason for any program: Being faster than handish human work.
except the captchas are designed to train bots to be better - why do you think they're all "select all of a frog" or "horse made of clouds" or something - you're training ai to generate images, that other ais will recognise, it's kinda wild.
Captchas 10 years from now: - Do a photorealistic drawing of a dog to prove you're a human - Win a TF2 match to prove you're a human - Write a song about proposing to a supercomputer to prove you're a human - Bake lemon macarons and mail them to the company to prove you're human - Translate the Voynich Manuscript to prove you're human
These captchas are almost like those free flash games we all used to play. I swear, if it keeps evolving like this, in 20 years we'll have to play a cs:go match to complete a single captcha.

Title: Worst CAPTCHA ever Video: The complete illustrated history of CAPTCHAs Bro, you anti-clickbaited me. I thought this was going to be some silly, vapid, time wasting horsesh*t I'm gonna watch, and you took me an entire emotional journey to Mordor and back. You had me questioning my humanity. You had me questioning Google's humanity (okay, that one's easy, but you still did it, so it counts). You are definitely getting subbed.
Half the time the robot I am trying to convince I am a human doesn't even know the answers itself. I had one that said "Identify the mailboxes" and it counted it wrong because it thought a brown trashcan on the side of the road was a mailbox.
Back in the days, I used a very simple mechanism to block contact form spam on my website: I put a checkbox under the form, with a little text instruction over it that said "Don't check the checkbox below". Then I used CSS to hide this checkbox as well as the text. Normally a user with CSS styles on wouldn't see the checkbox and its description, so he would leave it unchecked. Similarly, a human user with CSS turned off would see the ckeckbox along with its description, and followed the advice to not check it, so it would remain unchecked as well. But a bot would most likely just see the raw HTML encoding the form and try filling up all its fields with some random garbage or spam. On the back end, I checked if the checkbox field contained anything, and if it did, the message didn't pass through. Only the unchecked messages did. Simple and efficient.

I once got a CAPTCHA that drove me insane for almost an HOUR. It told me a certain number and showed me several images of dices (a few dices per image). I then had to calculate the sum of each image judging from the dots on the dices. But that alone wasn't annoying enough. It was TIMED. I was given around a minute to solve 9 fucking summations in dice-form. I either ran out of time before I could figure out which image was the right one, or made a mistake calculating due to the time pressure. And that wasn't even the worst. I had to go through that process more than once, and if I messed up at any point it would mean an instant restart and loss of all progress. It was truly infuriating, especially for someone like me who is a slow calculator.
slow calculator? its just stupid lol, i had to do one that was "click on the motorcycles" and i sat there screaming at a bunch of random people on motorcycles because i couldnt figure out if half a wheel in a different square was a part of the motorcycle. even the "which ones with bus" was dumb, i clicked all the buses, ALL OF THEM, and i guess it said that four crosswalks 2 cars and a fire hydrant were a BUS
@@Sarantis-107 I liked that one. It taught me that English speakers generally do not consider buses and trucks to be cars. Everything is a learning opportunity if you keep your mind open.
The ones that require you to pick the photos with certain images in them are actually meant for you to get wrong sometimes. The reason they sometimes have a square with a tiny piece of the traffic light on it or something is because the captcha knows that a human could miss those squares but that a robot would complete it perfectly without delay. This is why sometimes a captcha will let you into a website even if you don’t get it fully correct.
@@stm7810 actually yes it does. I've done so many recaptchas that I rarely read the the text anymore, I instantly start picking what seems "intuitive" to pick. Like if I see cars, then a picture of a bike I know that it's looking for bikes, if I see boats I know they want boats, see landscape I know they want hill side... some times I actually miss click images and still it accepts it, I'd say that 98% of the time I don't have to do another captcha even though I didn't read the text..... witch kinda makes me wonder, isn't the point of recaptcha to catch "bots" that don't read and just know the solution? also am I a bot? The new one with the animals is always throwing me off, but given enough time I'll probably get the intuitive feel of those challenges.... I guess that they could really just be testing intuitivety, as bots don't have intuitivety they just "know"
@@svampebob007 The problem might come from the fact that there's companies out there that would pay money in order to be able to ...I don't know... have bots advertising for adult sites write comments and chat messages (definitely an example that's completely unrelated to youtube). Which means that as long as human labor can be cheap enough, it becomes viable for other companies in low income countries to offer to have humans solve those captchas. And those humans will inevitably solve thousands of captchas per day; which means they stop bothering to read the prompt, and they develop their own subculture of what they consider a valid answer. And since each of those workers and offices solves so many captchas, they have much more influence on how future captchas are trained than any normal user.
A couple of weeks ago, Twitter presented a "pick the shadow that matched the icons at the top of the image" captcha. My twitter account was in a head lock for a whole 2 days because the captcha was impossible for me to complete. I tried to get my dad to complete the captcha as well, and he couldn't do it either. The only thing that saved me was when the captcha changed to something else.
I’ll be honest, finding Wally in a captcha is genius because it relies on pattern recognition rather than arithmetic and because it should be a bit of fun.
@@mikhail-cybertastic5349 Visually-impaired (fully or just partially blind) usually use screen-readers to travel the internet. It reads whatever is on the screen or what they are hovering over. How else do you think they made it to the website the captcha is on in the first place?
My favorite captcha was one that asked the user to click the animal that's walking backwards. The damn thing was so hard, I gave up trying to log into an account on an MMO's website. Many of my friends couldn't log in either. The problem was that the animals were walking in place on a white background - there's no sort of environment that's moving throughout the image to indicate which way theyre walking, so you have to think about the way an animals legs move. But that's hard to get correct four or five times in a row, which the captcha asked you to do
Have you had the "how long are the pants" captchas? After a few of those, I just wished that the internet would cease to be. It's bad enough already that apparently, most people think that anything(or part of anything) with 2 wheels is called a bicycle.
i remember the old recaptcha. it was such an asshole move to have us teach it, because it was clearly going to lead to captchas being more annoying in the future it was always fairly obvious which was the one we were teaching, so my method of coping was to always say the word was "butts"
as a visually impaired person, I absolutely despise captchas. Due to my poor eyesight I can just never figure them out and spend way too long solving them
hCAPTCHA allows you to get an accessibility cookie that bypasses the CAPTCHAs. reCAPTCHA has an audio captcha button that 60% of the time refuses you and tells you to screw off because it takes clicking that as a red flag that you're a bot (???)
The beauty of mini game CAPTCHAs is that it takes almost no time to develop a new variant of “add up to 12” but it takes days to develop (program/train) a bot-based solver for the new kind of CAPTCHA. Also, I noticed CAPTCHAs today are super time-consuming even if I can solve it and it seems it’s slowing me down intentionally to throttle traffic or limit number of accounts created per second.
@@melody3741 Usually, but once I encountered the sum dices to 14 captcha. You don't get just one sich image but like five of them. It is for some reason timed! I am pretty good at calculating but I am just not fast enough for that captcha. I got two of my friends to parallelize the captcha solvong. Each calculates one column and shouts if he sees the 14 sum. It still took us three attempts to get it done within the time limit. I think it took us at least 10 min to get past this captcha...
Actually of all the captchas mentioned, the one where you add up the numbers doesn't seem that hard. I've never done it but if the goal is to just pick a square that has a wheel of numbers, add them all up, see if that matches the correct value... that wouldn't be too hard to program in. You can just use OCR to extract every number from each wheel, and then run a sum total formula of all those numbers to see if it matches. Keep iterating through each wheel and viola. Not really all that hard.
It's interesting how as soon as self-driving cars were being more marketed and advertised as coming into existence suddenly captchas featured taxis and motorcycles, types of vans and cars, and especially traffic lights. so many traffic lights
Why are you saying that like it’s a unproven conspiracy lol. It’s well known they’re using them to train AI’s some of which drive cars. This video specifically brings that up like a few times at least 😂 Although I think it was more so for google street view than actual driving per se

_Ah yes, let’s block the user for taking too long to solve our ridiculous nonsense CAPTCHA, because bots are well know for their lengthy deliberation on how to solve a problem._
A really decent one was on a Japanese site where you not only had to slide a slider to line the hiragana symbols up but also answer what it told you to … in kanji this was used to teach a ai language model to translate between the two writing styles
@what the 4chan currently uses a slider with text based captcha. how it works is imagine those distorted text with lines captchas, and you cut some ovals into it. You’re supposed to line it up close enough to read the answer
Got the feeling that would be harder and harder for both human and computer to do it for Chinese and Japanese words are so blended together it's just hard to even tell which word is native and which is foreign in both languages nowadays, and that's not accounting everything that shows up before the 21st century that are by default considered all native (well, semi-native I mean, just like how people usually won't care that ketchup is a Chinese word).
I can't believe it never occurred to me we were training AI every time we logged into something. If you're not paying for the product, you are the product, and all that.
don't worry, even if you are paying for the product, your data is still a secondary product. marketers would never give up that info just because you paid them.
It was a fantastic idea. Kinda like those apps that use your extra computer/phone RAM when you're not using them to add to a cloud based supercomputer.
Back in the day (at 3:11) I do believe they advertised that detail publicly that the service helped to authorize you + translate scans of old books and articles. And like in the example in the video, you could often determine which word it didn't know, since it would be the less wavy/warped one, and if it was too hard to read you could get past the captcha by just writing anything you want
i once got a RIDICULOUSLY hard captcha, you had to make like 20 math problems in one minute, i remember being at my friend's house that time and none of us could do it
The AI getting so good at CAPTCHAs that humans couldn't do them gives me an idea: a CAPTCHA where in order to pass, you actually have to get the question wrong
It's just as easy for a computer to fail something as to succeed at something. Though your idea is still somewhat achieveable, but in a different way. Basically there are methods that targets specific machine learning algorithms that would encode an image in a way that would be invisible to human but would cause the algorithm to output a wrong answer with fairly high confidence score. Maybe the website could timeout any input that's wrong in a specific way because only AI that got hit by such attack would give that specific answer.
My question with the images has always been "How do they know I got it wrong if I am the one training their AI?" (I purposefully click wrong squares some times just to mess with the training)
@@Squant how can they, in good conscience, continue with their everyday work and hobbies, when they're basically training ai to read distorted words in scanned books and improve self-driving cars... the absolute NADIR of intelligence
I have a screenshot of one of these weird captchas that says, "Pick the smiling dogs." Underneath it is a bunch of poorly photoshopped dogs that look horrifyingly like skinwalkers.
I don't know why, but when it talked about how the 'select traffic lights' and those sorts of CAPTCHAs were from actual google maps images, my brain just exploded a little. I had no clue that the original text based CAPTCHAs were even used to teach AI how to read, and so with that knowledge, the second that it talked about traffic lights, I instantly realized what that actually meant. That's real cool, and extremely horrifying that I didn't even know what that was being used for.
15:25 the most obnoxious captcha I've encountered was trying to sign up for a throwaway email on outlook recently and it hit me with a captcha like this except with a series of incredibly abstract and highly distorted image matches requiring you match 7 to 12 different images and then it wouldn't even explicitly state if you failed it would just load a new sequence of images to match or rotate. I assume that means I failed but I am not sure as it never told me. It started to feel like the site was just farming captcha input and never actually going to give me an email address. Ultimately I left and signed up with a different provider lol.
One thing that I always found annoying about those early captchas is that, as a dyslexic person, I kinda struggled with them too, the occasional variation in fonts used and the distortions that got added later on made it so much harder for my brain to process what was in front of me when it already struggled with that enough on regular text. Sure it would normally get it eventually but it would take me quite a while, and sometimes it would take me a heap of captchas to get through that. As weird as some of them are, I'm glad they've moved on to imagine captchas, they're much more accessible and they don't make me feel terrible about not being able to read what's in front of me
@@trytoo5167 I'd realized there were accessibility issues, but you make a very good point. They're literally testing typical human abilities, so it's unavoidably non-accessible. Interestingly, the only way to do it well might be to have humans approve submissions, rather than computers.
I don’t have dyslexia but I still struggle with most text based captchas. They’re just hard in general, especially when it’s a guessing game of is it capital or lowercase, is the captcha even case sensitive idk fuck em lol
What's even worse nowadays is that you can cheaply buy a manual captcha solving service. So you have your bot interact with a website and when you're confronted with a captcha there's an actual person somewhere that solves it for you and you get back at botting...
some of the "move the x" capchas actually measure mouse movements. AI's movements are not as erratic and inefficient at human mouse movement. but if you try it on a touch screen... it sometimes thinks you are an ai
Yup. A programmed bot would move the cursor in a straight line to the target. You do pretty much the same thing with a touch screen and fail the captcha.
@@Unknown_Genius Sure I'm aware. The OP observed that "if you try it on a touch screen... it sometimes thinks you are an ai" vs. "erratic ... mouse movement", which is some of the information that a captcha looks for to decide that a human is present. By your reply, I gather that you're familiar with HIDs. In response to a) I think you'd agree that compared to a mouse, a touchscreen output is lower in resolution. Also, depending on the device, movement is often processed and filtered to make it more usable than it otherwise would be. So it doesn't surprise me that some movements of the x on a touchscreen could fall within a captcha's threshold for suspecting a bot. In response to b) We agree. I should have said that a basic script would move the cursor in a straight line to the target.

The one with Roblox kind of reminds me of the copy protection on old PC games where the obscurity was the point, you had to prove you had access to the manual in order to get in because the manual was hard to copy as opposed to the software itself which could be copied easily. Carmen sandiego had you looking up specific words in specific sentences on specific pages of the big fat reference book you were supposed to use to solve the in-game mysteries.
Yeah. I remember Return to Zork let you play up until the school house, where suddenly the teacher will give you a pop quiz of random questions (answers were in the manual.) Failure to answer correctly meant death.
I remember Tie Fighter had that security feature as well. I think Sid Meier's pirates also had something similar to find which ports had the treasure laden ships docked so you could raid the big bucks... Ahh that was so long ago.

Some memorable ones I had were Eric the Unready where you had to tell your armor sizes to the armor craftsman so that he can make the armor that fits you. Was pretty cool, but extremely easy to copy, since you just had to copy one page. Another was really annoying (TMNT) where there was a dark dark purple sheet with many hundreds of very tiny numbers (4 digits IRC) printed in black, and you had to say the number on row y column x, but it was so hard to read due to the small size and dark-on-dark colors. I was young so it wasn't too terrible, but I remember always breaking out the super strong desk light and looking closely.
Roblox has the strictest ones where I had to do TWENTY audio captchas because the images were completely unintelligible, only for an unknown error to occur making me have to do twenty MORE captchas
It's AI training. The captcha it's self is for training AI algorithms. It was never about preventing bots from using sites, it was about getting people to unwittingly do the hard work of training AI image recognition models.
Listen I hate google as much as the next person (and a lot more) but I have to disagree here. Yes I don't doubt that google is using users to train ai, but the main point is STILL to stop bots. (looking at some comment sections however, you can see just how effective or not it is.)
@@cact0s_ulion405 I mean main goal or not, fact remains if what they are actually doing helps bots better than it stops them, then they're effectively helping the bots. If we're the data they use for that, then we're the unpaid employees doing it. If you want to stop AI bots from getting in either switch it up so fast they can't get any significant data, or figure something out that AI actually cannot do. Problem is, this would cost a lot of time and money and the way they do it currently might suck but it gives them back a lot of time and money in the long run, so why would they change it?
OMG the math ones. Microsoft used those for a bit too. I was trying to help an older gentleman get back into his email account (I run an IT shop) and I COULD NOT answer them fast enough! I'm 37, not 5, and I took freaking calculus! The problem wasn't the math, it was the speed with which they thought you should be able to add all the numbers together in each box to pick the right one!

Real users can afford to spend fractions of a cent here and there as they browse normally, but operating a bot army at scale would no longer be free and would require an actual financial investment. There isn't anything new that bots could learn to defeat this (well, except maybe how to earn money..) Edit: Just to clarify why I mentioned Bitcoin (as opposed to a traditional payment system) is mainly because it is permissionless, meaning anyone in the world can easily opt in without needing to ask for permission by some third party. A traditional payment system would potentially exclude a lot of locations in the world from participating, and it might compromise the ability to browse anonymously.
The one thing I love about modern captcha is that they always make me think of the lyric "I'm not a robot and I'm not a monkey, I will not dance even if the beat's funky"
My least favourites are the one's that don't take into account language/country differences. Most of them seem American based, I'm not from there so sometimes I don't know what the thing is or what counts as one. I get through them in the end but sometimes they take me a while when I'm trying to decide whether the bit of road with pavement on each side but no crossing lines counts as a crossing
(Not)fun fact: They used such captcha on one Polish government site :q I bet lots of Polish citizens were unable to answer the English-language captcha, or even get what they're being asked to do :q 1:0 for the government though - they didn't have to deal with interesants for quite a while…
man im from america and i cant even do this. picture this, 3 buses. you click on the buses, and there are no more buses. YOU ARE WRONG. THE FIRE HYDRANT IS A BUS AND THE CROSSWALK IS A friggin bipod.
I remember the old captchas. It's always been pretty obvious which ones were transcription data and which ones were the actual humanity test, so I'd always transcribe it as something horribly incorrect. If Google wants me to work for them, they can pay me. Otherwise, they have no reason to be surprised that I'd make their transcriptions more colourful than they intended.
Google will honestily pay you as part of their survey programs to do stuff like this just like people are payed to test games. Not much but for a brief weekend payment it is something
roblox captchas are infuriating for 3 years there was a captcha that took 4~ mins per run and consisted of rotating an object to its correct angle, pressing it 7 times per turn usually. You would need to be pixel perfect and do it as fast as possible because if you spent 1 second doing anything else, after finishing it would say you did it wrong. The longest time i spent in one of those was 40 minutes. Did i mention that it starts with 7 objects, but more are expontentially added? One time i had 4 minutes to fix 45 objects that were low quality, grayscale shrubs. A shrub looks normal at any angle....
I would gladly contribute if someone starts an internet-wide trend of entering as much adversarial answers as allowed into the recaptchas to atleast slow down this nonsense. My friend keeps sending me screenshots of ridiculous acid trip captchas he keeps getting.
@@Oneiroclast Considering the word captchas are obsolete anyway, I was talking about image ones. Pretty sure there's an amount of error allowed there, especially with controversial squares. I wonder if it's possible to figure out how much you can mess it up and still pass, and do that every time.
my gripe with capthcas so far, is when they are the "click all images till none remain with X" because the moment they get laggy, you fail 100% of the time even if its correct. Even the "Choose all traffic lights" has issues where it reads things improperly. my favorite, is a mailbox was a traffic light, and it got mad saying i didnt select all traffic lights. Yes, i waited till the mailbox came back later and tested, selecting it worked..
"A Capcha needs to be easy enough for the dumbest Human, but too hard for the smartest AI." Me, an Intellectual: "Design a Capcha that blocks both Smart AI *and* Stupid Humans from using the internet. Never settle for solving just one problem at a time."
Good suggestion, but what if it surpasses all humans collectively? Considering the AI can infinitely grow unlike a human, it's not an unrealistic outcome. The question is, who uses the internet then?
@@The9thMonth That's just a matter of Natural Selection. "What if Neanderthal or one of the other hominids out-competed Homosapiens and humanity wasn't able to survive?" Well, then it would just be the decendents of the hominid species that *did* come out on top discussing Capcha here and now. If humanity really degrades to such a degree that no one at all is able to access the Internet except for a bunch of AI, then it means the AI are the new successful species; emergent life from synthetic origins. It could even have emergent sentience or even sapience. Just as a common ancestor of all hominids gave rise to one that would outperform the rest, so too in the natural order of things may we give rise to that which may be categorically better than us. If that's the case, then logically I can't find a practical, objective reason to arbitrarily judge the better to be less deserving than us. If AI truly become superior to mankind and mankind dies out as a result, it wouldn't be any different than the dying out of myriad previous transitional species; the only new matter would be that the format has shifted from analog to digital.
Mr. September The robots do. Once the robots become smarter than all humans, we’ll no longer be able to create CAPTCHAs that can stop them because they’re smarter than us.
My least favourite captcha is whatever the hell cloudflare does. It tries to check if I'm human by having me click a box. It loads. I fail the captcha. This is an endless loop. It turns out whatever cloudflare uses has a bug where it gets stuck in a loop if you have certain addons enabled. My adblock seems to be the culprit. I do not turn addblock off for any reason (and, *to be clear*, even when I did turn it off for the site, the site wouldn't recognise me, so I'd have to turn *the entire addon off*, which is a ridiculous hassle). Therefore I cannot load any site that uses this captcha.
So what you're saying is an AI is given the prompt 'make a horse that looks like clouds' and then needs to make that image, meaning it knows what 'a horse shaped cloud' looks like, meaning it can solve its own captchas. Incredible
@@UnleashedDan this. The amount of armchair computer scientists in this comment section is really something. I tend to not like the phrase "Armchair X" (because even non-"experts" can be knowledgeable if they have the right requisite knowledge) but jesus christ there is no other way to describe this comment section.
It's closer to running image recognition neural networks backwards. Say you had a Neural Network trained to tell the difference between "horses" and "clouds". You show it a bazillion pictures of horses and clouds and let it fiddle with its internal controls until it can answer, with acceptable accuracy, whether a new picture is a horse or a cloud. It does this by combining different "input layers" based on what it "sees", weighing these layers against one another in several different ways, and then getting two outputs; 1) how sure am I this is a Horse, and 2) how sure am I this is a Cloud. For example, it might end up 30% sure that it's a Horse and 50% sure it's a Cloud (implying 20% that it's neither, but it's *required* to pick one) so it picks Cloud since it's the higher surety. So, run it in reverse, give it 51% Horse and 49% Cloud on the backend and a catalogue of Google Image results to stitch together, and it will reverse-engineer a picture through its algorithm, using information from Google Images, to produce a picture that, if run the correct way through the program should give a result of 51% Horse and 49% Cloud.
@@numbdigger9552 You apparently have never heard of the DeepDream project or AI Inception. Look up either of those terms for more info. "The software is designed to detect faces and other patterns in images, with the aim of automatically classifying images.[10] _However, once trained, the network can also be run in reverse, being asked to adjust the original image slightly so that a given output neuron (e.g. the one for faces or certain animals) yields a higher confidence score._ This can be used for visualizations to understand the emergent structure of the neural network better, and is the basis for the DeepDream concept. This reversal procedure is never perfectly clear and unambiguous because it utilizes a one-to-many mapping process.[11] "
Words will never describe how much I hate captcha pictures. Its not because I find them JUST stupid, unnecessary or a waste of like 2 minutes. Its because I have undeniably horrible eyesight, I can barely see the chalkboard about 10-20 meters away from it, the issue with (mostly) picture captchas is absolute hell for me, their blurry, usually have noise over them, and are the opposite of clear. I can rarely see anything on the picture captchas, which make them extremely time consuming, way more then they should, up to 5-10 minutes.
10:44 Simi: “if so, you got it correct… which actually means you failed the captcha, as only a robot could possess that level of perception” Me who guessed it right: start searching for Sarah Connor
I also believe the recapture "I'm not a robot" one also tracks mouse movement through the page, a bot would tab or not even tab through the input fields as it fills out, where as a human would have their mouse move randomly about the page. There are multiple layers at work with all of them, somewhat fascinating.
That actually makes me a bit mad. I keep getting flagged because captchas think I'm a bot. I get banned from all sites that have this verification.. latest one was steam and I bought games and i just wanted to play one..
Most are genuinely used for security..it just has the ulterior motive of also teaching an AI; it's a "kill 2 birds with 1 stone" situation. It easily blocks out bots (as bots haven't learnt the material yet) whilst teaching bots how to do it..then it'll upgrade to something else and continue with the cycle
@testerwulf3357 the problem with claiming it's to stop bots is that often you can brute force them as they don't ever look you out just give you unlimited attempts.
@@stigmaoftherose Not really. I once got locked out of steam because my phone broke and it kept giving me capchas which wouldn't complete when i finished and i ended up doing like 12 before i got locked out.
The worst Turing test I've personally experienced was the one EA made me take when I was trying to create an Origin account to play It Takes Two. They made me count the values of a bunch of dice shown on various pictures, I have to do maths with them in order to choose the correct one. For every single question there were like 6 thumbnail sized squares of pictures and each picture contains like 6 dice, they weren't even positioned that straightforwardly and were stacked sometimes. You have to get 10 of those questions correct, in a row, AND IT HAD A TIME LIMIT.
Oh, that "select squares containing..." was such a failure. It took me fairly short time to determine what the robot expects me to pick, instead of what the correct answer is, and I would start selecting ads as road signs, not selecting partially obscured buses, marking private residences as storefronts, skipping cars in the distance, and ignoring bridges that occupied more than 80% of the photo. Because I knew the AI didn't know any better and would likely fail me if I submitted the correct answer, as opposed to the expected one. Congrats, Google, you have played yourself.
Actually captchas like that is being used to train AI on image recognition and we are simply being used as free labour to do that... By doing what you did you have effectively been sabotaging their AI training lol.
@@a64738 Yes. The old conundrum of AI scientists, give the solution to the problem they have vs the problem they pose to the AI - except this time applied to humans. Their goal: teach AI. My goal: get through the captcha. Where the two don't overlap, I take the route that solves the problem they posed to me, I'm not going to compromise my captcha solving time to correct the AI's misconceptions about the images.
The Captcha's are being used to train AI. At first we were entering words and wonky words. Then Google released "Screen Read" and "Translate". Then we were locating Traffic Lights in pictures. And the data was then used in self-driving vehicles. Now we are completing images of fruit etc. Because AR tech is gonna be the next big thing.
(3:35) It's not a great system though since I've seen Google books where they've used these reCaptcha answers as the scan-to-text, but the text is wrong. Usually when it's non-English text missing accented symbols which are important for non-English text. Plus sometimes most people might make the same error and only a few actually gets the correct answer. Since these words are shown out of context, and it's hard to tell what it is, but easy to tell when part of a full sentence. Basic example: З, this might look like the digit 3, but it is actually the Cyrillic Z. You can't tell out of context, but in the context of "Zlatoust (Златоуст) is a Russian city", you can at least tell it isn't a digit.
Google hasn't focused on non-English data mining as much, but it's ramping up. Pretty soon you will have trained an AI to defeat your language skills too, and do it at no cost to Google.
As I've worked in 2captcha for more than 3 years, I've actually faced every single type of captcha and recaptcha you mentioned in the video. Trust me besides all the types you mentioned, there's actually a lot more types of captcha out there that'll either amaze you or drive you nuts 😁😁
i personally really like Genshin Impact/Hoyoverse's take on the puzzle captcha. the image used for it is usually official artwork or a screenshot from the game. Pretty good way to incorporate your brand into it.
This reminds me of my favorite security question ever: If you were a piece of furniture, what would you be? It's simultaneously brilliant, ridiculous, extremely secure, and sounds like the author was extremely high when they wrote it 😂
Yes and similarly, "What is your favourite town/food/colour etc." I don't have one, or at least, if I can think of one now, there's very little chance that I'll remember it in six months time.
10:58 that ain’t no equation though. It’s the slope of the tangent curve on a point in that function. The answer should be 12cos(3x-pi/2) - 24sin(6x) for any given point. We are looking for the value when x=0, so the final answer is 12cos(-pi/2) - sin(0) which is 0
Yesssssss I was scrolling through the comments to find anyone else that did it, I also got 0 in my head Yeah not an equation but at least he noticed it involves trigonometric functions

I looked at this and I thought it was going to be a compilation of silly CAPTCHAs. What I got was much better. Thank you, I have learned something new today!
Ironically, complex math is the *worst* thing you could use for a captcha; that is what computers have *always* been better than us at. Humans excel at pattern recognition Computers excel at arithmetic
For that particular use case it makes sense. They're qualifying the human, robots aren't requesting true random numbers in huge quantities. If you need true random numbers rather than psuedo random you'll either be able to figure out the answer by googling steps/using wolfram alpha or find it fairly simple. In the example question it's clearly after recoganising sin(x-π/2) = -cos(x), that the derivative of cos(x) is sin(x), and that sin(0)=0. You don't even have to do any more work deriving it because you just know the answer is 0.
@@scragar It works because only that one site uses it, and nobody is going to train a computer to figure out integrals just to sign up to that one site. It's there to stop random bots that just fill in forms they find with the hope of posting spam to anything that looks like a comment field. Also their target audience shouldn't have any problems with the questions, so it's kind of a shibboleth as well.
What I hate is the infuriating ones where you click a correct box, and it slowly disappears to be replaced with ANOTHER picture, which is probably also a fire hydrant, so you have to click that, too.
Reminds me of that one time they censored hydrant's terminals. It must have mistaken them for woman's nipples.
Oh, yeah, I hate the repatition.
my guess is it's probably to avoid bots who are like insta-clicking the pictures and so the captcha is like "hey I didn't get time to load this next image, wth thats too fast". but idk /shrug

I was once given a captcha that asked to select the images of parking meters. One of the images was a plastic mailbox that the captcha thought was a meter. I failed the captcha for knowing it wasn’t a meter.
These capture images go to computers worldwide, American mailbox's can look very similar to parking meters in the UK and other countries around the world and the ai learning will be messed up by this.
And tbh, as a Brit, I originally thought those type of mailboxes were just a 'Hollywood movie' thing and didn't actually exist in real life (they do!). Cus why would anyone want potentially important letters placed in an easy to steal from box at the edge of the road... Just get a letterbox and have them pushed through your door directly into your houses. 🤣
@@Ryukai-san Unfortunately the United States is very large and there are many zip codes that mail needs to cover daily, and also people like to build houses separated from the road so letterboxes aren't thus fashionable. (Never lived in a city so I'm not sure about that, but I think for more cramped spaces in the US people either have a kind of have a wall/room of mail for their entire apartment/building where they go down to the desk and pickup their items (possibly get notified when some come in) or they have P.O. boxes)
Tangentially related: my current belief as to why some things are like that in the UK is that the UK has been built up through literal centuries and therefore has housing (and other) conventions that last past their age, as opposed to the US where there's so much land people can kinda "waste" or "recycle" land on the newer conventions
@@richardpike8748 In higher income areas its a bit better with a metal box that has little locked containers inside.
@@richardpike8748 Also it probably has something to do with the fact that Americans seem to think they need a car to travel a few hundred metres. Hell the amount of times while I have been there I have simply walked to the destination and been there waiting for them to arrive when we left at the same time is silly. Over distances that short the time taken to get into a car is a significant portion of the time needed to simply walk.
@@Ryukai-san Security might also play a role here. Here in Venezuela we have so little security that we don't trust some random getting close to our doors to leave the mail behind, instead we prefer to get from a little distance away from our front door.

All jokes aside it is just a matter of time before people get there. It is not a race of if it is when and google wants to be the first one there so.

In my opinion the most elegant one is the one where you simply click the "I'm not a robot" checkbox and all the analysis/evaluation is done behind the curtains.
Elegant and insidious. Elegant because it steals your habits without you realizing and insidious because those digital habits can be used for anything from placing ads where you can't ignore them to allowing hackers to bypass gateways by scripting mouse movements instead of other code more likely to be identified as a virus.
That's good because if filling out the form normally takes a human many seconds, a bot can't log into many sites per hour and the poor bot will get frustrated.
@@bob456fk6 -- Or you just run multiple instances of the bot set to type at human speed, using randomized variables to delay mouse movements and mimic human types of behavior, even occasionally making intentional "mistakes" to appear more human. People who code bots often have access to web logs and can see how real traffic behaves and, since the whole point of making a bot is to get money, they will implement those features.
Sadly it requires Google tracking you at all times
it is elegant, but with that you have to use other kinds of captcha to avoid false negatives

A lot of websites with recaptcha V3 actually do captcha but there is no button or anything. Dropbox's login page is an example.
it uses browser fingerprinting and analysing your mouse movements on the way to the checkbox, maybe checking cookies and whatnot too. if you use a privacy-first browser you'll probably never get just the checkbox and it will move on to having you solve a problem

You might be interested in Chinese CAPCHA too, they have evolved to rely on different uses of the Chinese language. For example:
1. As Chinese characters are basically square-y pictures, like 架, 奇, 雯 etc., they ask you to rotate a random character upright in the correct way. People who knows Chinese can do that effortlessly.
2. Different Chinese characters have the same or similar pronunciation, e.g. 忍, 人, 認, 刃, 仁, 韌, 飪... are all "ren" in mandarin, spoken in different tones, and all commonly used. So there is a CAPCHA for you to pick "which word sounds the closest to the given word". And also, to match the word to the given pinyin (i.e. "ren") and vice versa.
3. Three random, uncommon Chinese characters are given, and the distorted version on these three characters are hidden in a colourful picture. You are asked to click on each, according to the order they are listed in the question.
In order to get a Japanese google account, I had to answer a captcha with distorted Japanese text. Certain characters in Japanese are difficult to distinguish even when not distorted. Guess which characters they used!
There was like more than 1000 characters right?
The one’s I’ve encountered ask you to click on four characters part of an idiom (成语) in the order they appear in that idiom. They’re usually rotated and on some kind of background, as per usual captcha tests. Sometimes I have to pull out my dictionary if I don’t recognize the idiom 😂

Answer: Not long.
I think it was never about "How can we fool it" and always about "How long does it take until it's better than us".
That's more often than not the reason for any program: Being faster than handish human work.
AI is a lot smarter and faster than humans
except the captchas are designed to train bots to be better - why do you think they're all "select all of a frog" or "horse made of clouds" or something - you're training ai to generate images, that other ais will recognise, it's kinda wild.

- Bake lemon macarons and mail them to the company to prove you're human
- Translate the Voynich Manuscript to prove you're human

Back in the days, I used a very simple mechanism to block contact form spam on my website:
I put a checkbox under the form, with a little text instruction over it that said "Don't check the checkbox below". Then I used CSS to hide this checkbox as well as the text. Normally a user with CSS styles on wouldn't see the checkbox and its description, so he would leave it unchecked. Similarly, a human user with CSS turned off would see the ckeckbox along with its description, and followed the advice to not check it, so it would remain unchecked as well. But a bot would most likely just see the raw HTML encoding the form and try filling up all its fields with some random garbage or spam. On the back end, I checked if the checkbox field contained anything, and if it did, the message didn't pass through. Only the unchecked messages did. Simple and efficient.

I once got a CAPTCHA that drove me insane for almost an HOUR. It told me a certain number and showed me several images of dices (a few dices per image). I then had to calculate the sum of each image judging from the dots on the dices. But that alone wasn't annoying enough. It was TIMED. I was given around a minute to solve 9 fucking summations in dice-form. I either ran out of time before I could figure out which image was the right one, or made a mistake calculating due to the time pressure. And that wasn't even the worst. I had to go through that process more than once, and if I messed up at any point it would mean an instant restart and loss of all progress. It was truly infuriating, especially for someone like me who is a slow calculator.
Good, good, the humans are finally training :>
...and roblox thought it was a good idea to have that captcha.
it's blizzard isn't it
slow calculator? its just stupid lol, i had to do one that was "click on the motorcycles" and i sat there screaming at a bunch of random people on motorcycles because i couldnt figure out if half a wheel in a different square was a part of the motorcycle. even the "which ones with bus" was dumb, i clicked all the buses, ALL OF THEM, and i guess it said that four crosswalks 2 cars and a fire hydrant were a BUS
@@Sarantis-107 I liked that one. It taught me that English speakers generally do not consider buses and trucks to be cars. Everything is a learning opportunity if you keep your mind open.
The ones that require you to pick the photos with certain images in them are actually meant for you to get wrong sometimes. The reason they sometimes have a square with a tiny piece of the traffic light on it or something is because the captcha knows that a human could miss those squares but that a robot would complete it perfectly without delay. This is why sometimes a captcha will let you into a website even if you don’t get it fully correct.
SO it's punishing me for doing my best? I hate them even more.
yeah and then it starts to convince me that motorcycles are bikes because it doesn't let me in if i don't select the motorcycle...
@@randomclips9715 in some culture people call both motorcycles and bicycles as bikes. And well, I agree with you that captcha is unfair.
@@stm7810 actually yes it does.
I've done so many recaptchas that I rarely read the the text anymore, I instantly start picking what seems "intuitive" to pick.
Like if I see cars, then a picture of a bike I know that it's looking for bikes, if I see boats I know they want boats, see landscape I know they want hill side... some times I actually miss click images and still it accepts it, I'd say that 98% of the time I don't have to do another captcha even though I didn't read the text..... witch kinda makes me wonder, isn't the point of recaptcha to catch "bots" that don't read and just know the solution? also am I a bot?
The new one with the animals is always throwing me off, but given enough time I'll probably get the intuitive feel of those challenges.... I guess that they could really just be testing intuitivety, as bots don't have intuitivety they just "know"
@@svampebob007 The problem might come from the fact that there's companies out there that would pay money in order to be able to ...I don't know... have bots advertising for adult sites write comments and chat messages (definitely an example that's completely unrelated to youtube). Which means that as long as human labor can be cheap enough, it becomes viable for other companies in low income countries to offer to have humans solve those captchas. And those humans will inevitably solve thousands of captchas per day; which means they stop bothering to read the prompt, and they develop their own subculture of what they consider a valid answer. And since each of those workers and offices solves so many captchas, they have much more influence on how future captchas are trained than any normal user.
A couple of weeks ago, Twitter presented a "pick the shadow that matched the icons at the top of the image" captcha. My twitter account was in a head lock for a whole 2 days because the captcha was impossible for me to complete. I tried to get my dad to complete the captcha as well, and he couldn't do it either. The only thing that saved me was when the captcha changed to something else.

My favorite captcha was one that asked the user to click the animal that's walking backwards. The damn thing was so hard, I gave up trying to log into an account on an MMO's website. Many of my friends couldn't log in either. The problem was that the animals were walking in place on a white background - there's no sort of environment that's moving throughout the image to indicate which way theyre walking, so you have to think about the way an animals legs move. But that's hard to get correct four or five times in a row, which the captcha asked you to do

The beauty of mini game CAPTCHAs is that it takes almost no time to develop a new variant of “add up to 12” but it takes days to develop (program/train) a bot-based solver for the new kind of CAPTCHA. Also, I noticed CAPTCHAs today are super time-consuming even if I can solve it and it seems it’s slowing me down intentionally to throttle traffic or limit number of accounts created per second.

@@melody3741 Usually, but once I encountered the sum dices to 14 captcha. You don't get just one sich image but like five of them. It is for some reason timed! I am pretty good at calculating but I am just not fast enough for that captcha. I got two of my friends to parallelize the captcha solvong. Each calculates one column and shouts if he sees the 14 sum. It still took us three attempts to get it done within the time limit. I think it took us at least 10 min to get past this captcha...
Those dice captcha are just to hard for some people, who let they test them out? Mathematicians and math teachers?
CAPTCHAs wouldn't throttle traffic - It only delays it.
Actually of all the captchas mentioned, the one where you add up the numbers doesn't seem that hard. I've never done it but if the goal is to just pick a square that has a wheel of numbers, add them all up, see if that matches the correct value... that wouldn't be too hard to program in. You can just use OCR to extract every number from each wheel, and then run a sum total formula of all those numbers to see if it matches. Keep iterating through each wheel and viola. Not really all that hard.
It's interesting how as soon as self-driving cars were being more marketed and advertised as coming into existence suddenly captchas featured taxis and motorcycles, types of vans and cars, and especially traffic lights. so many traffic lights

Got the feeling that would be harder and harder for both human and computer to do it for Chinese and Japanese words are so blended together it's just hard to even tell which word is native and which is foreign in both languages nowadays, and that's not accounting everything that shows up before the 21st century that are by default considered all native (well, semi-native I mean, just like how people usually won't care that ketchup is a Chinese word).
I can't believe it never occurred to me we were training AI every time we logged into something. If you're not paying for the product, you are the product, and all that.
don't worry, even if you are paying for the product, your data is still a secondary product. marketers would never give up that info just because you paid them.
It was a fantastic idea. Kinda like those apps that use your extra computer/phone RAM when you're not using them to add to a cloud based supercomputer.
Back in the day (at 3:11) I do believe they advertised that detail publicly that the service helped to authorize you + translate scans of old books and articles. And like in the example in the video, you could often determine which word it didn't know, since it would be the less wavy/warped one, and if it was too hard to read you could get past the captcha by just writing anything you want

It's just as easy for a computer to fail something as to succeed at something.
Though your idea is still somewhat achieveable, but in a different way. Basically there are methods that targets specific machine learning algorithms that would encode an image in a way that would be invisible to human but would cause the algorithm to output a wrong answer with fairly high confidence score. Maybe the website could timeout any input that's wrong in a specific way because only AI that got hit by such attack would give that specific answer.

I assume that means I failed but I am not sure as it never told me. It started to feel like the site was just farming captcha input and never actually going to give me an email address. Ultimately I left and signed up with a different provider lol.

One thing that I always found annoying about those early captchas is that, as a dyslexic person, I kinda struggled with them too, the occasional variation in fonts used and the distortions that got added later on made it so much harder for my brain to process what was in front of me when it already struggled with that enough on regular text. Sure it would normally get it eventually but it would take me quite a while, and sometimes it would take me a heap of captchas to get through that.

The worst captchas were the ones where you had to determine the letters inside some squiggles, but no matter what, it would always say you are wrong.
Ah yes, the "ex-spouse" captcha.
What's even worse nowadays is that you can cheaply buy a manual captcha solving service. So you have your bot interact with a website and when you're confronted with a captcha there's an actual person somewhere that solves it for you and you get back at botting...
some of the "move the x" capchas actually measure mouse movements. AI's movements are not as erratic and inefficient at human mouse movement. but if you try it on a touch screen... it sometimes thinks you are an ai
I was thinking this what if you quickly swipe the slider to where it should be
Yup. A programmed bot would move the cursor in a straight line to the target. You do pretty much the same thing with a touch screen and fail the captcha.
@@Unknown_Genius Sure I'm aware. The OP observed that "if you try it on a touch screen... it sometimes thinks you are an ai" vs. "erratic ... mouse movement", which is some of the information that a captcha looks for to decide that a human is present.
By your reply, I gather that you're familiar with HIDs. In response to a) I think you'd agree that compared to a mouse, a touchscreen output is lower in resolution. Also, depending on the device, movement is often processed and filtered to make it more usable than it otherwise would be. So it doesn't surprise me that some movements of the x on a touchscreen could fall within a captcha's threshold for suspecting a bot.
In response to b) We agree. I should have said that a basic script would move the cursor in a straight line to the target.
I definitely get more captchas on my phone.

Bitcoin could be applied to solve this problem. Each person could have a layer 2 wallet into which they load some small amount of BTC. Charge a few satoshis to perform actions on each website where limiting bots is a priority.

There isn't anything new that bots could learn to defeat this (well, except maybe how to earn money..)
Edit: Just to clarify why I mentioned Bitcoin (as opposed to a traditional payment system) is mainly because it is permissionless, meaning anyone in the world can easily opt in without needing to ask for permission by some third party. A traditional payment system would potentially exclude a lot of locations in the world from participating, and it might compromise the ability to browse anonymously.

for 3 years there was a captcha that took 4~ mins per run and consisted of rotating an object to its correct angle, pressing it 7 times per turn usually. You would need to be pixel perfect and do it as fast as possible because if you spent 1 second doing anything else, after finishing it would say you did it wrong. The longest time i spent in one of those was 40 minutes. Did i mention that it starts with 7 objects, but more are expontentially added? One time i had 4 minutes to fix 45 objects that were low quality, grayscale shrubs. A shrub looks normal at any angle....

Let's make a bot that solves the first captcha right and the second one wrong lol

@@lombas3185 My man we figured that out years ago, certain site used that shit so you can imagine what n word did they put on.
They caught on to that very quickly and started to randomize which word is known and which is unknown.
@@Oneiroclast Considering the word captchas are obsolete anyway, I was talking about image ones. Pretty sure there's an amount of error allowed there, especially with controversial squares. I wonder if it's possible to figure out how much you can mess it up and still pass, and do that every time.
my gripe with capthcas so far, is when they are the "click all images till none remain with X" because the moment they get laggy, you fail 100% of the time even if its correct. Even the "Choose all traffic lights" has issues where it reads things improperly. my favorite, is a mailbox was a traffic light, and it got mad saying i didnt select all traffic lights. Yes, i waited till the mailbox came back later and tested, selecting it worked..
We gaslighted the google bot
"A Capcha needs to be easy enough for the dumbest Human, but too hard for the smartest AI."
Me, an Intellectual: "Design a Capcha that blocks both Smart AI *and* Stupid Humans from using the internet. Never settle for solving just one problem at a time."
Good suggestion, but what if it surpasses all humans collectively? Considering the AI can infinitely grow unlike a human, it's not an unrealistic outcome.
The question is, who uses the internet then?
@@The9thMonth That's just a matter of Natural Selection. "What if Neanderthal or one of the other hominids out-competed Homosapiens and humanity wasn't able to survive?" Well, then it would just be the decendents of the hominid species that *did* come out on top discussing Capcha here and now. If humanity really degrades to such a degree that no one at all is able to access the Internet except for a bunch of AI, then it means the AI are the new successful species; emergent life from synthetic origins. It could even have emergent sentience or even sapience. Just as a common ancestor of all hominids gave rise to one that would outperform the rest, so too in the natural order of things may we give rise to that which may be categorically better than us. If that's the case, then logically I can't find a practical, objective reason to arbitrarily judge the better to be less deserving than us. If AI truly become superior to mankind and mankind dies out as a result, it wouldn't be any different than the dying out of myriad previous transitional species; the only new matter would be that the format has shifted from analog to digital.
Mr. September
The robots do. Once the robots become smarter than all humans, we’ll no longer be able to create CAPTCHAs that can stop them because they’re smarter than us.
So basically what roblox did?
Just give everyone the calculus captcha
My least favourite captcha is whatever the hell cloudflare does. It tries to check if I'm human by having me click a box. It loads. I fail the captcha. This is an endless loop. It turns out whatever cloudflare uses has a bug where it gets stuck in a loop if you have certain addons enabled. My adblock seems to be the culprit. I do not turn addblock off for any reason (and, *to be clear*, even when I did turn it off for the site, the site wouldn't recognise me, so I'd have to turn *the entire addon off*, which is a ridiculous hassle). Therefore I cannot load any site that uses this captcha.
So what you're saying is an AI is given the prompt 'make a horse that looks like clouds' and then needs to make that image, meaning it knows what 'a horse shaped cloud' looks like, meaning it can solve its own captchas.
Incredible
Image generation is different from image detection
It's like drawing vs seeing
@@UnleashedDan this. The amount of armchair computer scientists in this comment section is really something. I tend to not like the phrase "Armchair X" (because even non-"experts" can be knowledgeable if they have the right requisite knowledge) but jesus christ there is no other way to describe this comment section.
It's closer to running image recognition neural networks backwards. Say you had a Neural Network trained to tell the difference between "horses" and "clouds". You show it a bazillion pictures of horses and clouds and let it fiddle with its internal controls until it can answer, with acceptable accuracy, whether a new picture is a horse or a cloud. It does this by combining different "input layers" based on what it "sees", weighing these layers against one another in several different ways, and then getting two outputs; 1) how sure am I this is a Horse, and 2) how sure am I this is a Cloud. For example, it might end up 30% sure that it's a Horse and 50% sure it's a Cloud (implying 20% that it's neither, but it's *required* to pick one) so it picks Cloud since it's the higher surety. So, run it in reverse, give it 51% Horse and 49% Cloud on the backend and a catalogue of Google Image results to stitch together, and it will reverse-engineer a picture through its algorithm, using information from Google Images, to produce a picture that, if run the correct way through the program should give a result of 51% Horse and 49% Cloud.
@@omargoodman2999 You can't run a neural network backwards. Your idea would probably end up producing random noise.
@@numbdigger9552 You apparently have never heard of the DeepDream project or AI Inception. Look up either of those terms for more info.
"The software is designed to detect faces and other patterns in images, with the aim of automatically classifying images.[10] _However, once trained, the network can also be run in reverse, being asked to adjust the original image slightly so that a given output neuron (e.g. the one for faces or certain animals) yields a higher confidence score._ This can be used for visualizations to understand the emergent structure of the neural network better, and is the basis for the DeepDream concept. This reversal procedure is never perfectly clear and unambiguous because it utilizes a one-to-many mapping process.[11] "

Words will never describe how much I hate captcha pictures.
Its not because I find them JUST stupid, unnecessary or a waste of like 2 minutes.
Its because I have undeniably horrible eyesight, I can barely see the chalkboard about 10-20 meters away from it, the issue with (mostly) picture captchas is absolute hell for me, their blurry, usually have noise over them, and are the opposite of clear. I can rarely see anything on the picture captchas, which make them extremely time consuming, way more then they should, up to 5-10 minutes.

Simi: “if so, you got it correct… which actually means you failed the captcha, as only a robot could possess that level of perception”
Me who guessed it right: start searching for Sarah Connor
lol
i assume it's a joke...
then again, maybe my professional Wii Party ball and cup gameplay has finally payed off
No "guess" is needed. It is clear to see.
I had a captcha yesterday, where I had to pick every horse that had white legs. They definitely did something.
I also believe the recapture "I'm not a robot" one also tracks mouse movement through the page, a bot would tab or not even tab through the input fields as it fills out, where as a human would have their mouse move randomly about the page. There are multiple layers at work with all of them, somewhat fascinating.
I thought normal people tab though forms... 🤔
That actually makes me a bit mad. I keep getting flagged because captchas think I'm a bot. I get banned from all sites that have this verification.. latest one was steam and I bought games and i just wanted to play one..
I love the fact that they literally used captchas to train an ai for image recognition and didn't expect it to immediately solve their own captchas
It was expected, imo.
Fun fact. Captchas aren't for security. They're to help teach the AI how to see more accurately.
Most are genuinely used for security..it just has the ulterior motive of also teaching an AI; it's a "kill 2 birds with 1 stone" situation. It easily blocks out bots (as bots haven't learnt the material yet) whilst teaching bots how to do it..then it'll upgrade to something else and continue with the cycle
@testerwulf3357 the problem with claiming it's to stop bots is that often you can brute force them as they don't ever look you out just give you unlimited attempts.
@@stigmaoftherose Not really. I once got locked out of steam because my phone broke and it kept giving me capchas which wouldn't complete when i finished and i ended up doing like 12 before i got locked out.
The worst Turing test I've personally experienced was the one EA made me take when I was trying to create an Origin account to play It Takes Two. They made me count the values of a bunch of dice shown on various pictures, I have to do maths with them in order to choose the correct one. For every single question there were like 6 thumbnail sized squares of pictures and each picture contains like 6 dice, they weren't even positioned that straightforwardly and were stacked sometimes. You have to get 10 of those questions correct, in a row, AND IT HAD A TIME LIMIT.
ohoho man i feel bad for ya
@@Da_Rivulet french "person"

ea literally just took your money gave you the game and locked it behind an impossible captcha

@@GooberInternet well i mean... they have a legitimate excuse, they're ea so they're allowed to do that
Why are people making math captchas? Computers ARE math, that’s like asking someone to prove they aren’t Lebron James by dunking
Oh, that "select squares containing..." was such a failure. It took me fairly short time to determine what the robot expects me to pick, instead of what the correct answer is, and I would start selecting ads as road signs, not selecting partially obscured buses, marking private residences as storefronts, skipping cars in the distance, and ignoring bridges that occupied more than 80% of the photo. Because I knew the AI didn't know any better and would likely fail me if I submitted the correct answer, as opposed to the expected one.
Congrats, Google, you have played yourself.
So you picking a private jet as "open road" must be why that Tesla crashed! Lol
Actually captchas like that is being used to train AI on image recognition and we are simply being used as free labour to do that... By doing what you did you have effectively been sabotaging their AI training lol.
@@a64738 Yes. The old conundrum of AI scientists, give the solution to the problem they have vs the problem they pose to the AI - except this time applied to humans. Their goal: teach AI. My goal: get through the captcha. Where the two don't overlap, I take the route that solves the problem they posed to me, I'm not going to compromise my captcha solving time to correct the AI's misconceptions about the images.
@@a64738 Not really, because 100 other people answered correctly, blurring out that little error.
The Captcha's are being used to train AI.
At first we were entering words and wonky words.
Then Google released "Screen Read" and "Translate".
Then we were locating Traffic Lights in pictures.
And the data was then used in self-driving vehicles.
Now we are completing images of fruit etc.
Because AR tech is gonna be the next big thing.
(3:35) It's not a great system though since I've seen Google books where they've used these reCaptcha answers as the scan-to-text, but the text is wrong. Usually when it's non-English text missing accented symbols which are important for non-English text. Plus sometimes most people might make the same error and only a few actually gets the correct answer. Since these words are shown out of context, and it's hard to tell what it is, but easy to tell when part of a full sentence. Basic example: З, this might look like the digit 3, but it is actually the Cyrillic Z. You can't tell out of context, but in the context of "Zlatoust (Златоуст) is a Russian city", you can at least tell it isn't a digit.
Google hasn't focused on non-English data mining as much, but it's ramping up. Pretty soon you will have trained an AI to defeat your language skills too, and do it at no cost to Google.
Cool
Captcha questions are slowly becoming Impossible Quiz questions. I wouldn't be surprised is Splapp was the one making them
As I've worked in 2captcha for more than 3 years, I've actually faced every single type of captcha and recaptcha you mentioned in the video. Trust me besides all the types you mentioned, there's actually a lot more types of captcha out there that'll either amaze you or drive you nuts 😁😁

i personally really like Genshin Impact/Hoyoverse's take on the puzzle captcha. the image used for it is usually official artwork or a screenshot from the game. Pretty good way to incorporate your brand into it.
Yea that's so easy to verify too
AI can learn that easily
This reminds me of my favorite security question ever: If you were a piece of furniture, what would you be?
It's simultaneously brilliant, ridiculous, extremely secure, and sounds like the author was extremely high when they wrote it 😂

10:58 that ain’t no equation though. It’s the slope of the tangent curve on a point in that function. The answer should be 12cos(3x-pi/2) - 24sin(6x) for any given point. We are looking for the value when x=0, so the final answer is 12cos(-pi/2) - sin(0) which is 0
Yesssssss I was scrolling through the comments to find anyone else that did it, I also got 0 in my head

Bro just called us bots for being able to solve a simple, slow-moving cup-and-ball puzzle, I've been able to do that since I was 8 😭
Ironically, complex math is the *worst* thing you could use for a captcha; that is what computers have *always* been better than us at.
Humans excel at pattern recognition
Computers excel at arithmetic
i think it's more like a joke to filter the smartest humans and bots before they enter your secret society lol
computers excel at excel
"Humans excel at pattern recognition.
Computers excel at arithmetic.
AI Deep Learning turns pattern recognition _into_ arithmetic."
For that particular use case it makes sense.
They're qualifying the human, robots aren't requesting true random numbers in huge quantities. If you need true random numbers rather than psuedo random you'll either be able to figure out the answer by googling steps/using wolfram alpha or find it fairly simple.
In the example question it's clearly after recoganising sin(x-π/2) = -cos(x), that the derivative of cos(x) is sin(x), and that sin(0)=0.
You don't even have to do any more work deriving it because you just know the answer is 0.
@@scragar It works because only that one site uses it, and nobody is going to train a computer to figure out integrals just to sign up to that one site. It's there to stop random bots that just fill in forms they find with the hope of posting spam to anything that looks like a comment field. Also their target audience shouldn't have any problems with the questions, so it's kind of a shibboleth as well.
