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.

Ok, so can we get rid of them then? They’re fucking annoying and waste time
Need these bots as a browser addon now. When your using a VPN these things are the bane of your Internet browsing experience.
And I’ll be fucked if I can get them right first time round half the time!
Hmmm… do you float if we throw you in the water?
I don’t use a VPN and they are still highly problematic. I get stuck in a cycle, like with cloudflare.

it switches to the accessibility version of CAPTCHA and uses speech recognition to solve it.
I’ve never been able to get this one to work, it will say it can’t detect speech even though I can hear it being played.
for me it works most of the time, and I don’t hear the speech being played at all while it’s being solved. and it the rare cases when it doesn’t detect speech, requesting another puzzle usually fixes it.
What’s ironic is that the main purpose of reCAPTCHA v2 is to train ML models. That’s why they show you blurry images of things you might see in traffic.
AFAIK the way it works is that of the 9 images, something like 6 are images the system knows are True or False, and another 3 are ones it is being trained on. So, it shows you 9 images and says “tell me which images contain a motorcycle”. It uses the 6 it knows to determine whether or not to let you pass, and then uses your choices on the other 3 to train an ML model.
Because of this, it takes me forever to get past reCAPTCHA v2, because I think it’s my duty to mistrain it as much as possible.
You’re wasting your time. Your fingerprint is graded and discarded if you’re not reliable
At least it adds noise to the system. It’s better than the people who are happily training the AI.
I need a bot then. I click through 7-8 of those and still don’t pass.
Mfw AI is better at proving they’re a human than I am
So the robots are now more successful at proving they’re human than I am.
From a UX perspective, those things are cancer.
I need a bot because I get stuck in a loop of captchas
It’s the age old question, does the pole count as part of a traffic light?
