| 摘 要： | 提出了在微机 Ｗｉｎｄｏｗ ｓ 环境下，联机签名鉴别的一种新方法。该方法的训练部分以普通动态匹配方法确定签名轨迹的点对对应关系，并以此为基础从真实签名样本训练得到标准模板、局部稳定性和判决门限。该方法的鉴别部分采用加权动态匹配，较好地弥补了普通动态匹配在签名鉴别这一特殊应用中的不足。该鉴别算法简单而高效，真实样本和非专业伪造样本的鉴别准确率达到９２％

| Abstract: | 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%. |
