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.

I fucking hate these. I’ve seen old people that don’t know any better get stuck on these for at least 30 minutes.
Same. That’s why Buster is my most recent must-have browser extension, alongside such greats as ublock and sponsorblock.
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.
They offer a sound option right below.
a hard to see option, aptly enough
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…

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.
I just close the page usually if I see one of these ones, I don’t have the patience to click all the boxes and then it just sends you a different one.
Unfortunately they’re on pages that I absolutely need to get into because my money is stored behind them. I cannot stand them, and I generally agree with you, if some random site has me doing a captcha in leaving.
I fail more of those checks then these AI bots do. Surreal.

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.
Bots are answering them wrong. Google takes the most submitted answer as truth.
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.
Pro-tip for webscrapers: using AI to solve captchas is a massive waste of effort and resources. Aim to not be presented with a captcha in the first place.
I think thats much more difficult than it seems, because usually only residential IPs are the ones that don’t get those. And if you start to use a residential proxy too much then that IP can also get flagged.
That’s why companies like Oxylabs exist
Depends on the case, sometimes its unavoidable.
That’s suspicious - I can’t pass 100%. here’s a new captcha for you: make the user do 100 in a row
- 100% is ai
- <50% is dumb “ai”
- in between is a person
we have trained them very well
So where’s my portable app to do so?
There’s a browser extension, but it uses an older technique of requesting the audio captcha and then parsing the words, which is probably more energy efficient anyway.
not at home but I believe there’s a few that run in docker.
Cool, so can Google shut it down now?
Our long international nightmare is finally over!
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!!
And yet I can’t beat the CAPTCHAs because reCAPTCHA doesn’t like VPNs lol
The capchas getting really bad on Mullvad almost made me give up on using a VPN. But then I learned about Buster.
This is my third post in a row shilling for this browser extension lol, it’s so good.
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.
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.
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.
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 reread his comment three times because I was convinced I must have read it in error somehow.
When it’s asking for motorcycles but it’s clearly a scooter
Worse is when its asking for crosswalks and its clearly a rumblestrip.
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?
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?
You know, regular buses
School busses and regular busses look completely different. What do those look like in your country?
Same as any bus
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?”
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.
