User Specific Parameters in One-class Problems: The Case of Keystroke Dynamics

Abstract: In this paper, we propose a method to find and use user-dependant parameters to increase the performance of a keystroke dynamic system. These parameters include the security threshold and fusion weights of different classifiers. We have determined a set of global parameters, which increase the performance of some keystroke dynamics methods. Our experiments show that parameter personalization greatly increases the performances of keystroke dynamics systems. The main problem is how to estimate the parameters from only a small user training set containing ten login sequences. This problem is a promising way to increase performance in biometric but is still open today.
