Abstract: Currently Cyber security is an important issue to tackle. A wide security primitive depend on hard challenges that can be computationally solved only by mathematical algorithms operations. Different user authentication methods are used for this purpose. There are many drawbacks in alphanumeric passwords that they can be guessed very easily or can be hacked. Currently researchers have proposed different graphical techniques such as CAPTCHA, PCCP, CaRP, PassMatrix, VRK, OTP & LTP etc. In this paper, we present a new security primitive based on hard AI 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 both a graphical password and a Captcha scheme. CaRP addresses a number of security problems altogether, such as online guessing attacks, relay attacks, and, if combined with dual-view technologies, shoulder-surfing attacks. This section makes a deep survey over the many existing systems and thereby makes a comprehensive evaluation of the existing techniques making us ready to propose a new technique system which eliminate the drawbacks of the previous systems. The paper describes and studies different application oriented graphical systems proposed earlier and tries to find the loopholes to avoid the attacks.
