A Keystroke Dynamics Based Approach for Continuous Authentication

Abstract

In this paper, we present the application of keystroke dynamics for continuous user authentication in desktop platform. We show the differences between static and continuous systems based on keystroke dynamics in terms of creating the template and authentication phase. The key factor in the continuous authentication system is monitoring the genuineness of the user during the whole session, and not only at log-in. Moreover, we propose a general approach for continuous authentication based on keystroke dynamics. In our experiments, we use the email application as a case study to present the effectiveness and efficiency of our proposed approach. Our main conclusion is that using keystroke dynamics can serve as a feasible and acceptable measure for continuous user authentication. The investigations have shown that it is feasible to authenticate users based on keystroke dynamics for continuous authentication systems. © Springer International Publishing Switzerland 2014.
