AJAX CAPTCHA

AJAX based CAPTCHA to determine if the user is a human.

If you are one those wondering what a CAPTCHA means. Here’s an explanation from WIKIPEDIA.
“A CAPTCHA is a type of challenge-response test used in computing to determine whether the user is human. The process involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.”
