Simţiţivă util atunci cînd reCAPTCHA va cere sa întroduceţi 2 cuvinte ;)

urmeaza descrierea la cum lucreaza reCAPTCHA:

reCAPTCHA seems like a perfect match for Google: it's a project that generates CAPTCHAs and uses the results to digitize books. "reCAPTCHA improves the process of digitizing books by sending words that cannot be read by computers to the Web in the form of CAPTCHAs for humans to decipher. (...) Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one."
