One thing we did for the Wells Fargo captcha for example is to pick up the audio version that's there for accessibility and parse that instead. Which makes me wonder now. These more hardcore captchas like Google's where you have to mark buses and traffic lights. How do they get around accessibility legislation? Whichever large service is relying on them can presumably get sued for a lot of money because some of them are very difficult even for a non-impaired person.
- YPPH 4y agoYou can use an audio alternative with ReCAPTCHA. I'm as critical of ReCAPTCHA as the next HN user, but their audio version is actually reasonable compared to the alternatives out there. It plays sensible and seemingly real audio (I'm assuming random extracts from YouTube videos), generally meaningful and audible, instead of random words with silly distortions.

- TechBro8615 4y agoThe audio version is frequently unavailable, especially if your IP address is assigned to a datacenter or Tor exit node.
- orbisvicis 4y agoI've heard one audio recaptcha that was explicitly sexual. Which I think is ironic considering captcha is used to censor the internet.
- thinkingemote 4y agoDoubly ironic as captcha was originally about opening up information by helping digitise scanned literature.
- SXX 4y agoI guess you wanted to say reCAPTCHA specifically. Captchas existed for decade before it.

- tobias2014 4y agoreCAPTCHA allows for audio challenges as accessibility fallback. And this has been a loophole for a long time to automatically solve them via google's own speech-to-text API https://github.com/dessant/buster https://github.com/dessant/buster

That was used to bypass reCaptchav2 [1]. This led to v3. [1] https://github.com/ecthros/uncaptcha https://github.com/ecthros/uncaptcha
- daveoc64 4y agoI think this just hasn't been tested in a legal capacity. The accessibility options of various captcha platforms leave a lot to be desired at best. At worst, they simply block users that can't see the visual challenge.
