Active authentication on mobile devices

Abstract

In recent years, we have witnessed a significant growth in the use of mobile devices such as smartphones and tablets. In this context, security and privacy in mobile devices becomes vital as the loss of a mobile device could compromise personal information of the user. To deal with this problem, Active Authentication (AA) systems have been proposed in the literature where users are continuously monitored after the initial access to the mobile device. In this chapter, we provide a survey of recent face-based AA methods.
