Abstract: 

The ubiquitous access to mobile devices exposes users to increasing threats of shoulder-surfing attacks. An attacker can spy on a user when he is entering a password, opening the door to various security threats. With the guide of shoulder-surfing resistance strategies and unique strengths of password and behavioral biometrics in mobile user authentication, we designed a touch gesture-based password authentication method. We empirically evaluated the performance of the proposed method against the traditional keystroke-based method in protecting users from shoulder-surfing attacks under various settings. The results demonstrate the effectiveness of the proposed method, and have implications for the design of password authentication method for mobile devices.
