title = "Towards Multiple User Active Authentication in Mobile Devices",
abstract = "Traditionally, practical authentication systems have considered only a single enrolled subject for verification. However, with the advent of mobile devices this paradigm has changed since a mobile device may be accessed by more than a single enrolled user. In this context, verification of multiple enrolled users has a practical importance. We address the issue of perfonnance degradation associated with multiple user authentication as compared to single user authentication. We interpret this problem in an open-set framework and introduce the notion of probability of negativity to alleviate the effect of multiple users in authentication. We further introduce a simple fusion scheme with the existing authentication methods to increase the intruder detection accuracy. Effectiveness of the proposed method is demonstrated using three publicly available face and touch gesture-based mobile active authentication datasets.",
