A New Security Primitive Based on Hard AI Problems and Efficient User Authentication using Captcha and Graphical Passwords
Bhagyashri A. Banarase , Prof. Meghali A. kalyankar
In this paper,I present a new security primitive based on hard AI (Artificial Intelligence) problems, namely, a novel family of graphical password systems built on top of Captcha technology, which we call Captcha as graphical passwords (CaRP) .CaRP is a combination of both a captcha and a graphical password scheme .With the hybrid use of captcha and graphical password one can addresses a number of security problems such as relay attacks, online guessing attacks and also shoulder surfing attacks.a new security primitive based on hard AI problems, namely, a novel family of graphical password systems integrating captcha technology, which is called CaRp (Captcha as gRaphical Passwords).CaRp is click-based graphical passwords, where a sequence of clicks on an image is used to derive a password. Unlike other click-based graphical passwords, images used in CaRpare captcha challenges .The CaRP scheme is enhanced with more attack handling mechanisms that improves the level of security in online application system and also provides better authentication .
