Most common computer authentication method is traditional ‘User Name’ and ‘password’. There are numerous Biometric authentication methods also proposed. In this paper, we propose a novel and new alternative; Figure as a Password. In this scheme users will get complete freedom to select their Passwords.

In this paper, we conduct an extensive survey of the existing graphical password schemes and propose an alternate scheme. Entire work can be divided into three phases- a. sampling of users passwords, processing and storage; b. security on transmission; and c. Recognition and authentication. Our scheme supports the application environment and we strongly believe that “User Authentication by Secured Graphical Password Implementation” could be a solid platform for future research and study.
