A Three Level Graphical Password Scheme for Providing High Degree of Security

Pranita H. Mokal | R. N. Denikar

Abstract: Many security primitives are based on difficult mathematical problems. Using hard AI problems for security is emerging as an new standard, but has been underexplored. As AI-complete problems cannot be solved by computer alone, but also require human computation, so that Captcha is used. In this paper, a new security primitive is proposed which is based on hard AI problems. In this paper, recognition based CaRP schemes are combined to develop a security primitive. The recognition based CaRP schemes are combined as input schemes. This primitive also combines Captcha. The input recognition schemes used are viz. ClickText scheme, ClickAnimal Scheme and AnimalGrid scheme. The proposed system is build on android platform. The proposed scheme is resistant to number of password attacks, such as online guessing attacks, relay attacks, and, if combined with dual-view technologies, shoulder-surfing attacks is resistant. In this paper, a new password scheme is developed to provide more security. This scheme combines recognition based schemes. In this scheme three levels of security is provided.
