Users are increasingly dependent on mobile devices. However, current authentication methods like password entry are significantly more frustrating and difficult to perform on these devices, leading users to create and reuse shorter passwords and pins, or no authentication at all. We present implicit authentication - authenticating users based on behavior patterns. We describe our model for performing implicit authentication and assess our techniques using more than two weeks of collected data from over 50 subjects.
