Behavioral biometrics have recently begun to gain attention for mobile user authentication. The feasibility of touch gestures as a novel modality for behavioral biometrics has been investigated. In this paper, we propose applying a statistical touch dynamics image (aka statistical feature model) trained from graphic touch gesture features to retain discriminative power for user authentication while...
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...
AbstractWhile enriching the user experiences, the developmentof mobile devices and applications introduces new securityand privacy vulnerabilities for the remote services accessed bymobile device users. A trusted and usable authentication architecturefor mobile devices is thus in high demand. In this paper,we leverage a unified structure, consisting of transparent TFTbasedfingerprint sensors, touchscreen,...
Securing the sensitive data stored and accessed from mobile devices makes user authentication a problem of paramount importance. The tension between security and usability renders however the task of user authentication on mobile devices a challenging task. This paper introduces FAST (Fingergestures Authentication System using Touchscreen), a novel touchscreen based authentication approach on mobile...
