Active User Authentication for Mobile Devices

Abstract

Enterprises today are dealing with the challenges involved in enabling secure and remote access for mobile device users. People often bring their personal mobile devices into works and use them to access corporate resources, and also store their private information on personal mobile devices. This has prompted investigation of new security policies and techniques. Authentication is the first gate for protecting access to personal mobile devices or access remote resources through personal mobile devices. Conventional authentication does not require user re-authentication for continuous usage of the devices. And attackers can target at a post-authentication session. In this paper, we study the active authentication for personal mobile devices and propose a biometrics based active authentication system. The proposed system is secure, effective and user-friendly. Our experimental results also show the feasibility of the proposed system.
