手写签名的快速认证

Rapid Verification for Handwriting Signature

提出了一种新的手写签名的快速认证方法，采用包括笔迹起点、终点信息、笔迹方向信息及笔画数等信息在内的匹配函数，将测试签名的特征和参考样板签名的特征进行匹配，判断真伪。在签名对准过程中，根据曲折点的曲率、方向确定旋转、平移变换，大大减少了对准时间。采用大量签名进行实验，该方法识别效果良好。

This paper presents a new rapid verification method for hand-writing signature. This method employes the matching function including the information of starting points, terminal points, chirography direction, the number of strokes to match the feature of test signature and template signature and judge ture or false. In the process of signature alignment, it reduces largely alignment time by assuring rotating and shifting transformation according to curvature and direction of zigzags. Experiments are made using a great deal of signatures and very promising results are achieved.
