The paper presented a new method of online signature verification in PC windows environment. In this method, training part determines the alignment of two signature traces by normal dynamic programming matching. And based on this, the normal pattern, local stability and decision threshold were obtained from reference patterns. Verification part adopts weighted dynamic programming matching to overcome the faults of normal dynamic programming matching using in online signature verification. This new method has low computation and high performance, and correction of the test of reference patterns and nonprofessional forgeries reaches 92%.
