摘　　要：目的探索电子签名笔迹的量化分析方法,以期实现对电子签名笔迹的检验。方法以电子签名笔迹为研究对象,通过分析电子签名笔迹的获取方式、表现形式,深挖签名过程中系统采集的大量数据,探求电子签名笔迹的信息内容,对电子签名笔迹开展量化检验。结果通过复原电子签名图像可对电子签名笔迹进行传统的形态学比较检验,通过分析书写时长、书写力度变化和书写速度变化等指标等可实现电子签名笔迹的量化检验。结论电子签名笔迹的量化检验方法具有可行性,能够为检案实践提供指导和帮助。Objective Along with the ever-increasing presence of handwritten electronic signatures(HES),more controversies are caused by the authenticity of such handwriting,therefore,it is necessary to implement quantitative examination on these handwritings.Methods HES,selected as the research object,were analyzed of their obtaining ways and expression forms so as to dig out the enormous data embedded during the signing process for exploration of the contained valuable information and approach of quantitative examination.Results Through restoration of the HES image,the involved handwriting can be verified of its authenticity by traditional morphology comparison.Through analysis of writing time,writing pressure and writing speed,the quantitative examination can be realized into HES.Conclusion Quantitative analysis method is feasible for the examination of handwritten electronic signatures.
