奥博8000笔迹量化检验仪鉴别写字机仿写签名字迹

Verification of the Writing-machine-forged Signatures based on AB8000 Handwriting Dynamic Analysis System

目的研究写字机仿写签名字迹的特征及变化规律,实现写字机仿写签名字迹的鉴别。方法通过收集、制作实验样本,使用奥博8000笔迹量化检验仪对写字机仿写签名字迹和被仿写真实签名笔迹开展比较检验,分析写字机仿写字迹的特征反映。结果写字机仿写签名字迹与被仿写真实签名的区别一方面体现在笔顺、运笔、笔痕等传统的静态特征上,另一方面则表现在笔力分布、执笔角度、墨迹宽度等可量化的动态特征中。结论奥博8000笔迹量化检验仪作为辅助性仪器能够有效鉴别写字机仿写签名字迹,为笔迹鉴定提供了一种新手段。

Objective the characteristics and changing rules of writing-machine-forged signatures were investigated,in order to realize the identification of the imitated signatures on the writing machines.Methods By collecting and making experimental samples,the authors used AB8000 Handwriting Dynamic Analysis System to compare the imitated signatures with the real ones,and analyzed the characteristics of the imitated signatures.Results On one hand,the differences between the imitated signatures and the real ones were reflected in the traditional static characteristics such as stroke order,stroke movement and stroke mark.On the other hand,the differences were reflected in the quantifiable dynamic characteristics such as stroke force distribution,stroke angle and ink width.Conclusion As an auxiliary instrument,AB8000 Handwriting Dynamic Analysis System could effectively realize the identification of writing-machine-forged signatures,which provides a new way for handwriting identification.
