Mobile Security

We are working towards improving security of mobile devices. In [1], we analyze the permission requests of more than 180,000 Android applications. We find statistically relevant permission request patterns that correlate with the user ratings of an application. In [2,3], we propose a continuous authentication method based on the way how users touch the touch-screen of their device. In [4], we investigate how the periodic syncronization and update behavior of installed smart phone applications reveal the identity of the phone. Finally, in [5], we argue that security mechanisms of smart phones should adapt to the usage context and to the environment of the phone.
