Perl implementation of the reCAPTCHA Mailhide API

Captcha::reCAPTCHA::Mailhide - A Perl implementation of the reCAPTCHA Mailhide API reCAPTCHA is a hybrid mechanical turk and captcha that allows visitors who complete the captcha to assist in the digitization of 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. More specifically, each word that cannot be read correctly by OCR is placed on an image and used as a CAPTCHA. This is possible because most OCR programs alert you when a word cannot be read correctly. http://recaptcha.net/learnmore.html
