Anyone who has been surfing the web for a while is probably used to clicking through a CAPTCHA grid of street images, identifying everyday objects to prove that they’re a human and not an automated bot. Now, though, new research claims that locally run bots using specially trained image-recognition models can match human-level performance in this style of CAPTCHA, achieving a 100 percent success rate despite being decidedly not human.
ETH Zurich PhD student Andreas Plesner and his colleagues’ new research, available as a pre-print paper, focuses on Google’s ReCAPTCHA v2, which challenges users to identify which street images in a grid contain items like bicycles, crosswalks, mountains, stairs, or traffic lights. Google began phasing that system out years ago in favor of an “invisible” reCAPTCHA v3 that analyzes user interactions rather than offering an explicit challenge.
Despite this, the older reCAPTCHA v2 is still used by millions of websites. And even sites that use the updated reCAPTCHA v3 will sometimes use reCAPTCHA v2 as a fallback when the updated system gives a user a low “human” confidence rating.

This is actually a good sign for self driving. Google was using this data as a training set for Waymo. If AI is accurately identifying vehicles and traffic markings, it should be able to process interactions with them easier.
As I understand it, the point of those captchas was never really “bots can’t identify these things” (though you’re right on that it was used to train). They use cursor movement, clicks, and other behaviours while you’re solving it to detect if you are a bot or not.
The image choosing was always just to train their own bots
It’s a combination.
Most captchas goals generally aren’t 100% prevention, it’s to put a workload in front, this makes spamming the site cost money, a bankrolled attempt could just as easily outsource the captchas to real humans.

Exactly. I’ve been using 2captcha for that for over a decade now
Since I started getting good at yosu and that fishing mini game in farmrpg I’ve been failing more captchas. I wonder if they’re related knowing this
Is that why I’m asked to do this over and over for 14 million times when I’m on a VPN?
It is probably part of it, yeah. But to be clear I’m not a captcha expert or anything, just a layman.
The annoying thing is that they held us hostage for our free labor, but the results are proprietary for Google’s benefit only.
That training data ought to be forced to be made freely available to the public, since we’re the ones who actually created it.
Afaik this is precisely what the captcha data was intended for - training AI models. Originally leveraged machine learning. LLMs are a slightly different paradigm but same purpose and results here.
i hope you’re joking. please, tell me you’re joking?

Its never been confirmed by Google, so I may be wrong. It still tracks that the data harvesting company with a AI self driving car project would use free human labor to identify road hazards.
I was referring to the “This is actually a good sign for self driving” part of their comment.
The captcha circumvention arms race has been going on for over two decades, and every new type of captcha has and will continue to be broken as soon as it’s widely deployed enough that someone is motivated to spend the time to.
So, the notion that an academic paper about breaking the current generation of traffic-related captchas (something which the captcha solving industry has been doing for years with a pretty high success rate already) is “good news” for the autonomous vehicle industry (who has also been able to identify such objects well enough to continue existing and getting more regulatory approval for years now) is…
Not really. I’m not even sure what you’re disagreeing with based on the above comment.
My point is that if bog standard AI can accurately identify all of the road information from pictures, that is good news for self driving.
What was once a nearly impossible task for computers is now mundane, and can be used to improve safety/utility for self driving, especially for FOSS projects like comma.ai
And yet I can’t beat the CAPTCHAs because reCAPTCHA doesn’t like VPNs lol
Captcha these days isn’t even really a CAPTCHA in the traditional sense since most of the work it does is based on filtering of IP and browser fingerprinting, with a certain level of gamification because the goal is not just to keep out the people they fight against, but to waste their time, would work great if it didn’t waste normal people’s time, while real bad actors have easy ways to get around it.
I was going to say I’ve straight up just left whatever website I was trying to access because I was stuck in some endless loop of clicking on street crossings, buses, bikes, and street lights.

Fellow vpn user here, it’s been really bad lately. I’m definitely installing this.
So can we stop using those damn things? They’re super annoying!
I’m kind of hoping the AI permanently beats them. I hate them too.
Just means they’ll get harder, but maybe not for people, just needs to be harder for a computer
Aren’t these Captchas designed to get training data for AI models anyway?
“System does what it was designed to do” doesn’t feel that surprising…
Aren’t these Captchas designed to get training data for AI models anyway?
Yes and no, the captchas are just meant to be hard for computers to solve but easier for humans. People saw that, and thought that “if we’re making people do this might as well have them do something useful” not meant to be malevolent- and the purpose is still stopping bots, training them is a side-effect.
No, you’re wrong, the Traffic Light examples ARE specifically to gather data to train models. Being a good Captcha was just a byproduct of that. If people just wanted a good captcha they wouldn’t need hundreds of millions of photos of street lights and bicycles.

No you’re wrong, because the sites that embed those captchas on their page are not doing that to help good.

Yes, they are getting something productive out of the human labor that would be done anyways. Trust me as a web developer, and web scraper, some kind of captcha is necessary for many free services to be useful/economically viable. The core of a good captcha is just making it marginally more expensive for the scraper/bot than it is for you.
The sites don’t create the captcha, you yourself just said it was embedded there.
They embed for a reason… And the captchas wouldn’t exist if they weren’t embedded anywhere
Finitebanjo is right. Yes they are used to fight spam and bots but they way they do it us is picked intentionally to train ai.
https://medium.com/@yennhi95zz/how-google-trains-ai-with-your-help-through-captcha-876cb4eb4d01
Also from the Wikipedia article “Google profits from reCAPTCHA users as free workers to improve its AI research.” https://en.m.wikipedia.org/wiki/ReCAPTCHA
they do it us is picked intentionally to train ai.
Yes like I said, the challenges were picked to be useful. But some form of challenge would’ve been chosen regardless.
Well yeah, I’d hope so, that’s the entire point.
Catcha’s data collection always was with the intent for training ai on these skills. That’s “the point” of them.
It’s reasonable to expect that the older version of captchas can now be beaten by modern ai, because they’re often literally trained on that exact data to beat it.
Captcha effectively is free to use on websites as a tool because the data collection is the “payment”, they then license that data out to people like OpenAI to train with for stuff like image recognition.
It’s why ai is progressing so fast, captchas are one of humanity’s long term collected data silos that are very full now.
We are going to have to keep progressing the complexity of catches as it will be the only way to catch modern AIs, and in turn it will collect more data to improve it.
Yeah, my understanding is that these capchas were made to harvest data to use for AI/Autopilot driven cars. That’s why they are always having you identify motorcycles, bycicles, crosswalks, stoplights, busses, etc. It’s all stuff that automatic driving cars have had a hard time identifying.

I wanted to use 4chan alot before I came here, but FUCK that slider capcha. I bailed after the first time I didn’t pass.
I wanted to use 4chan
I am relatively confident that you are one of the first people to ever type that sentence out.
I reread his comment three times because I was convinced I must have read it in error somehow.
4chan is more than /b/ and /pol/, you know. The porn boards are pretty good at least
I think I’m good on that, but you do you m8.
I fucking hate these. I’ve seen old people that don’t know any better get stuck on these for at least 30 minutes.
it’s super ableist. if someone has poor vision or colorblindness chances are they’re going to miss things.
I have regular everything and I still fuck them up. “click the ones with a fire hydrant”. But a tiny piece of fire hydrant is spilling into another box. Does it count? Does it not count? Good luck!!
I had one the other day that was deep fried jpegs to the max. Like, what the fuck am I supposed to do.
Sprinkle powdered sugar on them. Delicious deep fried jpegs.
Spillovers into other boxes definitely count…
I don’t want to do this next part but I can’t resist…
Just ask my girlfriend…
Ba dum tiss
FYI as someone that’s colorblind these captcha’s don’t seem to have anything specially relevant to being colorblind in them.
Now if they start showing me a dozen traffic cones and asking me to pick the green one, we might have a problem.
They offer a sound option right below.
a hard to see option, aptly enough

When it’s asking for motorcycles but it’s clearly a scooter
Or, like, “there’s the bottom 10% of a traffic light in this one. Do I click that box? Ia that supposed to count?”
What they are doing is comparing your answer and seeing if it is consistent with how it has been answered previously. They realize that not everyone is going to give the exact same answer, so as long as you answer it in a way that enough other people have answered it, it should let you in.
I’ll usually go with the minimum number of clicks that I think will get me through, since I’m lazy and it’ll also at times slow down how fast you can click which is annoying.
I’ll also answer them wrong if I think it’s a mistake that enough other people will make. “Yes… that RV over there is a bus…”
They are also overly US centric.
One of the questions asks you to click on only the school buses. I had to Google how you tell the difference between a school bus and not a school bus.
Also is it a crosswalk if it’s at an intersection or is it only a crosswalk if it’s in the middle of a road somewhere?
The questions either need to be not cultural or they need to be adapted for where they detect the user is coming from, the first option seems easier.
Interesting. Do you not have school buses, or are school buses not distinctly marked? How do kids get to school when it’s beyond walking distance?
They are just buses.
I guess the British government just assume that school children are smart enough to get on the right bus without them being individually distinct.
I knew school buses are yellow but I did not realize that they are always yellow. I did not realize that the yellow color meant school. I just assumed that the yellow color was a color busses could be.
Maybe it’s lack of transit in the us, I don’t know. Almost every public school district I’m familiar with, uses standard yellow school buses to bring kids to and from school. However Boston city schools give the kids an MBTA pass - I don’t know if that differed by age - and I imagine that’s true of other downtown schools where there’s transit
The size of the UK verses the exponentially larger size of the US probably has a lot to do with it.
And if you knew school busses where yellow… Where’s the problem?
You know, regular buses
And, you know, school busses.
Now imagine if they looked this same loo
School busses and regular busses look completely different. What do those look like in your country?
Well here in, not the United States of America land, we just have busses. I was not aware that busses required a special magic paint job.
I suppose the paint job prevents school shooters wasting their time.
So if your regular bus is shown next to a bus that’s not “just a bus”, and you’re asked which one is a school bus… What would you answer?
Same as any bus
So if you see a picture that obviously a regular bus, alongside a different bus, what would you infer from that when asked which bus is not the same as “any bus”?
How would you know what is a regular bus and what is not a regular bus for a given country?
Does the backside of a traffic light even count? What about these strange traffic lights that have more boarder than light?
How about “do they want just the bulbs or the pole holding it up?”
That tip of a handle bar that makes you wonder if that square counts or not.
Or the square with the driver in it: does it classify the driver as part of the motorcycle?
Does it count when the AI driving the car clips it?
I had one with one of those Motorcycles with the long handles, apparently they aren’t part of the bike, but the dudes foot holding it up is.
I think the reason AI are better than humans is that the AI is just as stupid as the image classifier.
Worse is when its asking for crosswalks and its clearly a rumblestrip.
Buster is awesome to get past recaptcha. I use it with my own Speech to Text API key since its free from Google. Using Google to beat Google.
It’s so funny that this exists. I’m going to check it out!!
If you’re using a personal api from google, is that a way that google can track you? Part of using a VPN, noscript and adblock for me is to prevent that kind of tracking.
Nothing is truly free with Google. So ya, most likely they are tracking. If you dont want to use Google, there are other options on their wiki
https://github.com/dessant/buster/wiki
If not, you can use a dummy account just for this.
Wait, so if a visitor fails the v3 Captcha, v2 is used as a fallback?
That makes absolutely no sense.V3 isn’t necessarily more effective than V2, it’s just less obtrusive.
Not quite: it’ll drop a v2 captcha for you to solve when a v3 one can’t clearly classify you one way or another.
So if v3 isn’t entirely sure you’re human, it’ll make you do a v2.
And if you fail the V2, it’ll just take your word on it and let you pass anyway.
god I fucking wish

But, I cannot pass those 50% of the time… what does that mean?
Ever watched Bladerunner?
My mother? I’ll tell you about my mother…
It means Rick Deckard won’t be coming for you any time soon.
You’re walking in the desert and you see a tortoise
Is it an Agassiz or a Morafka?
You should schedule an eye appointment.
Everywhere I look, all I see is fire hydrant, buses, and bicycles
My score is lower.
I can see a future where the Internet is completely run by bots and AI to the point where no human actually uses the Internet anymore.
It’s like an island that gets overrun with rats - there are just too many to deal with so you leave.
Some believe this happened years ago. Check out Dead Internet Theory.
I’m already doing that now. If Lemmy starts showing signs of fuckery I’m out. I’ll switch back to magazines.
I already did… There’s some subscription stuff where you can read pretty much all available magazines and papers, it’s been a long time since I’ve been reading that much “news” and reports
I work in a place with no phones. I bring books and magazines into the shitter.
Basically Cyberpunk, people only interact with the night city intranet because the global internet has been taken over by AIs.
Yeah, I predict that in the future, you can’t expect that content on the internet is written by humans. If you go to the internet, then it will probably not be to connect to other humans. Maybe you want to know something that a bot can tell you or you have some administrative task to fulfill, like filing a form.
Cool, so can Google shut it down now?
I fail more of those checks then these AI bots do. Surreal.
It seems like every other captcha I get has a picture of a moped and asks to click for a motorcycle. When I don’t click on the moped it says I’m wrong. Pisses me off.
Just be very general, don’t get stuck in the details.
It goes against my human nature to not overanalyze.
leaves plastic banana under your bed
You’ll find that, months from now, and you won’t know where it came from, or why it’s there.
than* these AI bots
Bots are answering them wrong. Google takes the most submitted answer as truth.

I mean, we literally train them by completing the CAPTCHAs. Why do you think you were picking things like bikes, traffic lights, cars, and busses? The only question now is what’s next…
they embed dark souls into the browser
