摘　　要：电子签名在提高办公效率的同时,也给犯罪活动提供了可乘之机。当电子签名的数据信息出现争议时,能否引入电子数据检验方法对其进行量化分析,是当前研究的一大方向。本实验选取蒙括旗下的两种不同规格的电子签名板做为实验签名板,选取5人作为签名书写者,记录下书写者的书写数据。通过分析数据,引入单一电子签名板的各项指标参数,在签名面板的可视化程度、电子签名板的笔迹的压力、瞬时速度、书写时间、时间间隔五个方面对两块电子签名板进行对比研究。实验发现,在压力大小特征的记录上两块签名板存在一定的差异,在压力走势特征的记录上两块签名板都具有稳定性;书写者的书写时长特征相对稳定,两块签名板的可视化程度没有对书写时长产生影响;时间间隔在传统形态上反应为笔画数,两块签名板没有因笔画数不同而出现较大差异,以上结论都对笔迹鉴定具有较大价值,可以为电子签名板的笔迹鉴定提供一定参考。While improving office efficiency,electronic signatures also provide opportunities for criminal activities.When there is a dispute over the date information of electronic signatures,it is a major direction of current research to introduce electronic data verification methods for quantitative analysis In this experiment,two electronic signature boards of different specifications under Mengtian were selected as the experimental signature boards,and five people were selected as the signature writers to record the writing data of the writers By analyzing the data and introducing various index parameters of a single electronic signature pad,the two electronic signature pads are compared in five aspects:the degree of visualization of the signature panel,the pressure of the handwriting of the electronic signature pad,the instantaneous speed,the writing time,and the time interval.Through experiments,it is found that there is a certain difference between the two signature pads in the record of the pressure size feature,and the two signature pads have the stability in the record of the pressure trend feature;the writer's writing time feature is relatively stable,the visualization of the signature board of the two signature pads has no effecton the writing time;the time interval is traditionally reflected as the number of strokestand the two signature boards have no major difference because of the difference The above conclusions are of great value for handwriting identification and can be used as electronic signatures The signature and handwriting identification of the board provides acertain reference.
