A verification methodology for computer systems users
Mohammad S. Obaidat · 1995
This paper presents techniques to verify the identity of computer users using the keystroke dynamics of computer user's login string as characteristic patterns for pattern recognition and neural network techniques.This work is a continuation of previous work done by the author[l-3) where only interkey times were used as features for identifying computer users.In this work we used the key hold times for classification and then compared its performance with the former technique.Then we use the combined interkey and hold times for the identification.We applied several neural network and pattern recognition algorithms for verifying computer users as they type their password phrase.The performance of several variants of backpropagation paradigms as applied to this problem was studied and investigated.
