基于概率统计的签名认证系统的研究与应用

Research and Application of Probabilistic Feature-based Signature Authentication

针对签名在办公自动化系统中的广泛应用,该文首先对各种签名识别技术进行介绍、分析和比较,然后介绍了一个基于生物特征手写签名认证的系统原型,并着重提出了基于概率统计的手写签名识别方法。

Based on the extensive application of hand-writing signature in the o ff ice automation systems ,we describe a new method to identify the writer and en hance the security of OA systems.Firstly we introduce and analyze the signatur e verification technology,and then,a prototype of the OA system based on signa ture authentication is proposed.Then,we propose the detail of the new method using probabilistic feature modeling.
