摘　　要：针对传统动态时间规正算法速度较慢的缺点,提出基于特殊点的动态时间规正在线手写签名认证算法。特殊点包含了丰富的签名信息,表现了签名者的基本生物特征。该算法缩短了身份认证的时间,提高了身份认证的效率。实验结果表明,该方法速度快、识别率高,进而证明在线手写签名在身份认证中具有很好的应用前景。Against the disadvantages of classic DTW low speed on verification, proposes an online handwritten signature verification algorithm based on DTW using special data points. The special data points can contain a number of information about signature characteristics, and these information may reveal basic characteristics of the signatory. This algorithm rapidly shortens verification time while the target of verification is similar to that of classic DTW using the whole data points. The result of experiment proves that this algorithm obtains a good verification effect. It is suitable to use online handwritten signature as a method of identity verification.
