ABSTRACT

The variables that help make a handwritten signature a unique human identifier also provide a unique digital signature in the form of a stream of latency periods between keystrokes. This article describes a method of verifying the identity of a user based on such a digital signature, and reports results from trial usage of the system.

REVIEW

"Stanley A. Kurzban : Reviewer"

The authors present a thorough and useful description of their work on the use of keystroke latencies (the intervals between successive keystrokes) to authenticate the identity of a computer user. Their approach requires each user   more...
