The Impact of Database Quality on Keystroke Dynamics Authentication.

This paper concerns keystroke dynamics, also partially in the context of touchscreen devices. The authors concentrate on the impact of database quality and propose their algorithm to test database quality issues. The algorithm is used on their own <KDS database> as well as the well-known <Keystroke Dynamics - Benchmark Data Set database>. Following specific problems were researched: classification accuracy, development of user typing proficiency, time precision during sample acquisition, representativeness of training set, sample length.
