Keystroke analysis as a method of advanced user authentication and response

Abstract

There has been significant interest in the area of keystroke analysis to support the authentication of users, and previous research has identified three discrete methods of application; static, periodic dynamic and continuous dynamic analysis. This paper summarises the approaches and metrics arising from previous work, and then proceeds to introduce a new variation, based upon application-specific keystroke analysis. The discussion also considers the use of keystroke analysis as a progressive, escalating response measure in the context of a comprehensive user authentication and supervision system, presenting an example of how this could be realised in practice.
