Abstract

Graphical passwords have been proposed as an alternative to alphanumeric passwords with their advantages in usability and security. However, most of these alternate schemes have their own problems about memorability. Biometrics schemes are not widely adopted though they need no remembrance and provide the highest level of security, owing to their great cost both in device and time. In this paper, we explore the feasibility of introducing hand-based biometrics into the realm of graphical passwords with a simplified scheme named PassHands. PassHands has similar authentication form with Passfaces and has the advantages of unnecessary to remember the password and unpredictable of user choice. Some primary experiments are conducted and the results illustrate the performance of PassHands.
