Abstract

Password authentication has become a widely recognized element of computer security practices, where human users are proven or confirmed as legitimate users for access to secure systems. Every user needs to recall its password correctly before access can be granted to an intended system. Remembering the secure password chosen from mixture of random alphanumeric and non-alphanumeric characters is an everyday problem for all users because of individual memory limitation. In an effort to solve this problem, users tend to choose insecure passwords that are making most systems vulnerable to many attacks. Instead of using secure-but-difficult to remember or unsecure-but-easy to remember alphanumeric password, now graphical password which works just by clicking with a mouse or stylus could be used for user authentication. Graphical password is able to solve the problem of alphanumeric password being hard to remember. The main objective of this paper is to provide a comprehensive survey of array of draw-based graphical password schemes and capture the memorability of each scheme in a table. We highlight what makes images memorable and recommend that choice of background image in a scheme could affect how memorable it is because not all images are equal in memory
