摘要
选取21名志愿者,利用电子签名设备提取本人签名、代签签名、摹仿签名笔迹样本,经过数据采集和统计软件记录并分析出书写时长、书写压力、书写速度三种动态特征的量化数据,对这些数据进行分析、比对,结果发现同一人签名的动态特征数据表现出相似性;代签签名与本人签名的动态特征数据差异明显;摹仿签名与本人签名笔迹尽管在形态特征上相似,但二者的动态特征数据差异明显。因此,同一人电子签名笔迹动态特征具有稳定性,利用动态特征的量化数据可以区分不同人的电子签名笔迹。
21 volunteers were selected to extract normal signatures and copy handwriting samples with electronic signature equipment. After data collection and statistical software recording, quantitative data of handwriting dynamic characteristics such as writing time, writing strength and writing speed were analyzed. The results show that the electronic signature of the same writer’s normal handwriting shows similarity in the quantitative data of dynamic characteristics. Although the morphological characteristics of the electronic signature handwriting of the imitator and the writer are similar, the quantitative data of the dynamic characteristics of the two are obviously different. Therefore, the dynamic characteristics of electronic signature handwriting of the same person are stable, and the quantitative data of dynamic characteristics can be used to distinguish electronic signature handwriting of different people.
