John Resig - OCR and Neural Nets in JavaScript Just google for "CAPTCHA Breaker" or pwntcha and you'd have much more advanced captcha breakers capable of much more. But javascript won't be able to handle ...

The code is designed specifically for this CAPTCHA style, but there's no reason why the getImageData trick combined with a alternate OCR implementation couldn't be used to solve for other systems. This is pretty fascinating stuff. Is there a better (more convenient, harder to cheat) way to prove humanness? What else could you make in Javascript using OCR, neural nets, or per-pixel image processing?
