Abstract: |
CAPTCHA is an acronym for "Completely Automated Public Turing test to tell Computers and humans Apart." The process usually involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade .CAPTCHA is an image of distorted letters is dynamically generated. Since the letters are a part of an image and not text, it is difficult for a spam bot or other computer program to read. Captcha is a so called win-win solution, in that if a bot cannot break it, it provides security, but if it is automatically broken, that means that a difficult task in computer vision or related areas has been solved. . A common type of CAPTCHA requires that the user type letters or digits from a distorted image. The most common form of CAPTCHA requires visitors to type in a word or series of letters and numbers that the application has distorted in some way. CAPTCHAs are classified based on what is distorted and presented as a challenge to the user. |
