Investigating the Challenges Facing Behavioral Biometrics in Everyday Life

Abstract

The rapid progress of ubiquitous devices’ usage is faced with equally rapid progress of user-centered attacks. Researchers considered adopting different user identification methods, with more attention towards the implicit and continuous ones, to maintain the balance between usability and privacy. In this statement, we first discuss biometric-based solutions used to assure devices’ robustness against user-centered attacks, taking the inertial sensor-based gait identification for example. We finally discuss the challenges facing these solutions when integrated with everyday interactions.
