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 de- scribed in the current literature and show through experimental data how the metric of consecutive keystroke latencies is inade- quate for user authentication. The insuffi- ciency gives the motivation for exploring other keystroke metrics. We design, test, and evalu- ate four different metrics relating to keystroke analysis.
