In the Network Security, many security primitives are there based on hard mathematical problems. A new paradigm is emerged as an exciting one for the security using hard AI problems. In this paper we present a new security primitive based on hard AI Problems namely CaRP(Captcha as Graphical Passwords). It is a novel family of graphical password systems built on top of captcha technology. It is a graphical password scheme as well as it addresses a number of security problems such as online guessing attacks, relay attacks, shoulder surfing attacks. A CaRP also offers a novel approach to address the image hotspot problem in popular graphical password systems such as passpoints, that lead to week password choices. CaRP is not a proper solution but it offers security and usability for some practical applications for improving online security.
