Security Enhancement of Recall Based Graphical Authentication System by Using Biometric Features
Notation of graphical passwords was first introduced by the researchers. They presented two classes of graphical password schemes that were, recall-based graphical passwords and recognition-based graphical passwords. Studies have showed significant convenience in remembering pictorial representation of passwords over the textual passwords. The motivation behind exploring a graphical password scheme is based on the remarkable ability of humans to recall pictures easily. In this paper, the authors are presenting the novel approaches for security of pure recall based techniques with the help of biometric authentication i.e. stroke analysis and mouse movement.
