Enhanced User Authentication Through Keystroke Biometrics
Edmond Y. Lau, Xia Liu, Xiao Chen, Xiao Fang Yu · 2004
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. 1
