Dynamic Game Based CAPTCHA-A New Approach to Tackle Web Robots

Abstract

Abstract: "CAPTCHA" stands for Complete Automated Public Turning Test [1], is a security mechanism designed to differentiate between online bots and human. It is a challenged- response test for computing to determine whether the user is human or not. It is used to defend against the malicious bots programs. As use of Internet has been become vital issue and many web application facing a threat of web bots (Robots). Web Bots or, Robots is an automated script which executes over an Internet and occupy web space and increases the network traffic [6] [7]. The complication with currently used CAPTCHA i.e., text-based CAPTCHA or, graphic-based CAPTCHA is that, it is it is troublesome to read even for the human and Image based or, voice-based CAPTCHA has been broken many times. In this CAPTCHA, We can store 3-4 GUI game on our server. If the user successfully completes the game then only he/she will login. This CAPTCHA game will change as many times user login. As the game will change randomly, so for the web bots it would be difficult to solve this CAPTCHA but for the human it would be easy. This paper discusses the existing CAPTCHA and dynamic game-based CAPTCHA.
