Abstract

A CAPTCHA is a program that can tell whether its user is a human or a computer. CAPTCHAs are used by many websites to differentiate between the bots (automated program) and the human. The main motive behind using the CAPTCHA is to prevent abuse from "bots," or automated programs usually written to generate spam. The CAPTCHA basically uses images in distorted form that is difficult to read by the bots but they can be read by the human being easily. The websites which provide free services to the users some anonymous user can make false enrollment on the websites with the help of automated computer program. CAPTCAHS are used to prevent the false enrollment. One of the CAPTCHA methods is Collage CAPTCHA. In this method some shapes are shown with distortion and the user is asked to choose a specific object.
