Abstract: In this paper, we present a new approach for user biometric verification based on keystroke dynamics. In our approach, the performance of simple classifiers (namely KNN and Bayes classifiers) is tested in a user tuned feature selection method, based on a open password approach. The impact of the training set size is studied, obtaining good results in a preliminary study on a population of 20 users.
