Continuous mobile authentication using a novel graphic touch gesture feature
2013 IEEE sixth international conference on biometrics: theory …, 2013•ieeexplore.ieee.org
Behavioral biometric on mobile devices has begun to gain attention in recent years and the
feasibility of touch gestures as a novel biometric modality has been investigated lately. In
this paper, we propose a novel Graphic Touch Gesture Feature (GTGF) to extract the identity
traits from the touch traces. The traces' movement and pressure dynamics are represented
by intensity values and shapes of the GTGF. To evaluate its usability on the authentication
problem, touch gesture datasets have been collected which includes six commonly used …

Behavioral biometric on mobile devices has begun to gain attention in recent years and the feasibility of touch gestures as a novel biometric modality has been investigated lately. In this paper, we propose a novel Graphic Touch Gesture Feature (GTGF) to extract the identity traits from the touch traces. The traces' movement and pressure dynamics are represented by intensity values and shapes of the GTGF. To evaluate its usability on the authentication problem, touch gesture datasets have been collected which includes six commonly used touch gestures. A Equal Error Rate of 2.62% has been achieved combining six gestures together, which demonstrated the effectiveness of the proposed methods.
