Authorization Using Captcha As Graphical Password

Many security problems are based mainly on hard mathematical problems. Using hard AI problems for security is appearing as new sample but has been in under-development. In this paper we present a new security scheme known as Captcha as gRaphical Password (CaRP). This scheme is concept of Graphical Password built on top of Captcha. CaRP addresses number of security problems such as guessing attacks, relay attacks, and many more such security problems. CaRP also addresses a well-known problem of graphical password such as image hotspot. CaRP fits well with some practical applications to improve online security.
