User Recognition by Keystroke Latency Pattern Analysis

Dawn Song - Peter Venable - Adrian Perrig

April, 8th 1997

Abstract:

We analyze keystroke latency patterns to identify the person typing on the keyboard. Unlike previous work in this domain, which focused on taking one reference sample and doing user authentication based on the reference sample only, we continuously sample user input and use the data for identification and further learning and refinement of the user model.
