摘要
目的 在签名鉴定中能够快速准确地发现并分析笔压特征,实现对纸笔签名和电子签名的关联检验.方法 开发了静态签名笔压特征分析系统,对纸笔签名的笔压进行可视化分析;开发了动态签名笔压特征分析系统,对电子签名的笔压进行量化分析.结果 利用两种系统,鉴定人能够准确对黑色中性笔签名进行笔压可视化检验、对电子签名进行笔压量化检验以及对两类签名进行笔压特征关联检验,提升签名鉴定的正确率.结论 静态签名和动态签名笔压分析系统能够辅助实现签名笔压特征的分析与量化检验.
Abstract
Objective To analyze pen pressure characteristics fast and accurately in signature examination,and realize correlation examination between signatures on paper and digital signatures.Methods A static signature pen pressure characteristic analysis system was developed,which enables the visualization analysis of pen pressure in signatures on paper.Moreover,a dynamic signature pen pressure characteristic analysis system was developed for the quantitative analysis of pen pressure in digital signatures.Results The two systems allowed the examiners to perform visualization analysis of pen pressure in black gel pen signatures and quantitative examination of pen pressure in digital signatures.A related examination of pen pressure in both types of signatures was achieved,improving the accuracy of signature identification.Conclusion The static and dynamic signature pen pressure characteristic analysis system can assist in the quantitative analysis of pen pressure in signatures.
