reCAPTCHA is a new idea to me, although I am more aware of CAPTCHA. Upon surfing for ways to put a CAPTCHA on some of my webpages, via wikipedia I learned of reCAPTCHA at
http://en.wikipedia.org/wiki/Captcha Two of the links at wikipedia were especially interesting to me. http://captcha.net/ http://www.wired.com/techbiz/it/magazine/15-07/ff_humancomp My question about reCAPTCHA is whether it makes sense or not: it sounds like potential legitimate web users are expected to require their human cognition skills to read text that has been derived from real documents in a way that the legitimate web user's efforts are supporting some legitimate OCR activity. While I do see that legitimate human intelligence can be used to read unclear text, I don't see how this can be used to frustrate hackers from altering web pages because if the text has not been deciphered yet, then how can it be validated and thus used to keep out hackers? Likely I am missing something here, but I wonder if someone can explain this. This is important to me because I would like to add one of the "free" reCAPTCHA implementations to some of my pages.
