Keystroke Dynamics. How typing characteristics differ from one application to another

Abstract

This Master thesis is about continuous authentication using keystroke dynamics. We will look to the typing characteristics in different applications and how those characteristics vary from one application to another. It is proved that there are differences in those typing characteristics when the user try to use different applications, However we need to investigate those differences to see if we can still authenticate a person regardless which application is used. In other words, by looking at a selected numbers of applications, we are trying to answer a question "‘Does a template based on a certain application allow a person to use another application and still be authenticated by the system "’?. Furthermore we will look if it is possible to authenticate a person based on one general template or we need a set of application dependent templates?
