N66001-13-C-3002 -This proposal introduces a seamless user authentication solution whose overarching goal is to balance the accuracy of the authentication with the usability of the system. Thus, our proposal is relevant to TTA #3. The solution we propose uses the sensors embedded on most of today’s smartphones to determine, securely store and update unique user behavior patterns. We then use these patterns to provide seamless user authentication: only when the user’s behavior is outside normal parameters, its access to the mobile platform becomes conditional on the user’s ability to explicitly authenticate… One of the goals of our work is to determine which sensor readings can be used to uniquely identify users while at the same time provide sufficient entropy to ensure the security of the authentication process. In particular, we need to completely eliminate false positives – user is allowed continued access even though it is not the owner. We also need to reduce the number of false negatives, in order to improve the solution’s usability. Finally, we also aim to reduce the cost, size and to improve power efficiency of the hardware and software components required by the solution.
