Applying keystroke dynamics on one-time pin codes
Patrick Bours, Elnaz Masoudian · 2014
In this paper the problem of applying keystroke dynamics on one-time PIN codes, consisting of 6 digits each, is addressed to investigate if it can be used for user authentication and identification purposes. In other research in static keystroke dynamics, the password/PIN code of a user is fixed, hence the template will contain exact information on how a genuine user types this information. The novelty in this paper lies in the fact that a user will be challenged every time with a new 6-digit number which he/she might never have typed before. We will show that in this situation we can still derive Keystroke Dynamics related features that allow a user to be authenticated. In a small scale experiment we obtained an EER of 26%.
