Enhanced User Authentication Through Keystroke Biometrics

In this paper, we look at several metrics for keystroke-enhanced user authentication. We begin by introducing keystroke biometrics and looking at its advantages and disadvantages. We examine a statistical analysis method described in the current literature and show through experimental data how the metric of consecutive keystroke latencies is inadequate for user authentication. The insufficiency gives the motivation for exploring other keystroke metrics. We design, test, and evaluate four different metrics relating to keystroke analysis.
