Abstract:
The ability of having a secure mobile device is determined by different aspects (e.g., hardened system, authentication or anti-virus). Normal authentication methods are only requesting authentication characteristics at the beginning of the usage. The aim of this paper is to create a framework which can continuously analyze which user is using the device at each moment. While mobile devices are easy to lose or can be stolen, it is important to do an authentication process during usage. We propose a continuous trust model using keystroke dynamics and movements of the device as biometrical modalities to have a certainty of the usage at each time.
