Implicit Pass Point Scheme for Password Authentication

Authentication is the first line of defense against compromising confidentiality and integrity. Though traditional login/password based schemes are easy to implement, they have been subjected to several attacks. As an alternative, token and biometric based authentication systems were introduced. However, they have not improved substantially to justify the investment. Thus, a variation to the login/password scheme, viz. graphical scheme was introduced. But it also suffered due to shoulder-surfing and screen dump attacks. In this paper, we introduce a framework of our proposed (IPSPA) Implicit Passpoint Scheme for Password Authentication, which is immune to the Common attacks suffered by other authentication schemes and using mathematics techniques to reduce time complexity.
