Stop Spam read books

Filed under: Info — gurulib @ 2:25 pm

After reading about the recaptcha project at CMU from BBC website, I implemented the much needed reCAPTCHA on the sign in page of GuruLib. A CAPTCHA (Completely Automated Turing Test To Tell Computers and Humans Apart) consists of an image containing letters or numbers which have been heavily distorted, making it hard or impossible for a bot to “read.”[1]

reCaptcha is an attempt to use human intelligence to decode text from old manuscripts and books that are sometimes impossible for a machine to decode. So reCaptcha not only keeps spam robots away but also helps CMU with their text digitizing project. This is a wonderful example of using the power of internet to solve a problem.
