Mobile devices offer access to our digital lives and thus need to be protected against the risk of unauthorized physical access by applying strong authentication, which in turn adversely affects usability. The actual risk, however, depends on dynamic factors like day and time. In this paper we discuss the idea of using location-based risk assessment in combination with multi-modal biometrics to adjust the level of authentication necessary to the situational risk of unauthorized access.
