Gesture and Sociability-based Continuous Authentication on Smart Mobile Devices
Zachary I. Rauen, Fazel Anjomshoa, Burak Kantarcı · 2018
In this paper, we propose a new continuous verification platform on smart mobile devices. To this end, we integrate gesture-based features with interaction with social networking apps to verify user identities without minimum requirement for a password, pin code or biometric means. The continuous verification subsystem of this work proposes a novel two-step system for verification of users. The subsystem works by having two accurate models working as a primary and backup; when the primary fails the backup takes over to confirm or deny the conclusion of the primary model. The false acceptance rate (FAR) and false rejection rate (FRR) achieved under the proposed two-step system are shown to be 2.54% and 1.98% respectively, compared to the FAR and FRR of single-step verification, which achieved 3.15% and 9.13% respectively. Furthermore, the proposed system also improves the stability of continuous verification. In this work we show that the single step systems are inconsistent when analyzing small feature sets or slightly varied datasets. During both of these instances, the proposed system stays consistent, maintaining a high verification rate.
