Abstract

Passwords are the most common form of authentication. The password memorability problem is magnified with increasing number of systems users have to access. Graphical authentication systems (GASs) have received significant attention as one potential alternative to alphanumeric passwords to provide more usable authentication. In this paper we review all the existing work which had explored the memorability of multiple graphical passwords. The review reveals that human memory capabilities should not be overestimated and the password memorability problem remains unsolved, even when graphical passwords are employed. Hence we propose a novel graphical authentication system with certain new security features which could solve the problem. This paper will be of interest to Human Computer Interaction-Security researchers investigating approaches to usable and secure authentication techniques.
