Study on Keystroke Dynamic with Feature of Pressure

Abstract

This paper introduces a new database structure which is different from the existed one that only consists of press and release time. To improve, we add eigenvalue of pressure to it and we compare the results of new database structure with the old one to clarify whether the adding eigenvalue of pressure can improve the efficiency of the system. In addition, we come up a different keystroke dynamics method, Hidden Markov Models, to examine the efficiency of the new database structure and compare it with the results from another similar one, One-Class Support Vector Machine, to figure out whether Hidden Markov Models will behave better.
