Comparison of point selection for characterizing on-line signature

Authentication systems based on biometrics are becoming popular. One of them, authentication by handwritten signature, is the most accepted due to the fact that it is easy to use. In this paper we present a comparison of methods for efficient point selection for on-line signature authentication purpose. 5 methods are presented based on different selection criteria. The efficiency of these methods is measured by the recognition rate. The comparison method used is Dynamic Time Warping.
