摘　　要：在线手写签名认证是以人的行为特征为基础的身份认证技术。对在线手写签名字型曲线进行分段,分析了一系列特征,并将隐马尔可夫模型(HMM)引入到在线手写签名认证中。找到了真签名中某种比较稳定的特征,提出了一种基于隐马尔可夫模型的在线手写签名认证方法。从实验数据来看,取得了比较满意的认证效果。On-line handwritten signature verification is an identity authentication technique which takes person＇s behaviour characteristics as the basis. A series of characteristics were analysed by segmenting Chinese characters style curves in on-line written signature, and Hidden Markov Model （HMM） was introduced to on-line handwritten signature verification. After a relatively stable dynamic characteristic being found in genuine signatures, an on-line handwritten signature verification method based on HMM is presented. Satisfied verification effects are achieved from the experimental data.
