Study On Handwriting Identification Of Normal Electronically Captured Signatures

With the development of science and technology,digital writing signature has been gradually improved and applied to more and more fields.The writing carrier ranges from POS machine to touch pad to digital board and digital screen.Therefore,with the development of the application of this technology,corresponding judicial expertise requirements have been put forward.When the judicial appraisal institution receives the appraisal commission for digital signature handwriting,it cannot always ignore the appraisal in this aspect or leave it in the situation of "not having the appraisal conditions".The related researches at home and abroad have been carried out step by step,but they still need to be improved.The first part of this paper is mainly about the definition of the concept of digital writing signature handwriting and the summary of the current research situation,which lays a foundation for the subsequent development.The second part is to design experiments,observe the experimental results,and summarize the characteristics of digital handwriting signature from the experimental results.Through comparing the digital signature handwriting written again with the traditional paper pen form handwriting compare the feature point,observe the different characteristics of digital signature handwriting writing point of the original traditional paper and pencil handwriting reflect the degree of feature points,and within the normal range of writing speed change and the feature point paper tries to research the laws between the reflection degree,analysis characteristics reflect the degree of difference and the reasons for the formation of;The third part is the second part according to the experiment and the analysis of the causes of the formation of the phenomenon,combined with the practical application of handwriting identification and operation mode,explore how to apply traditional handwriting identification of mature specification to digital signature handwriting identification,writing is put forward in the actual digital signature handwriting identification of writing should pay attention to some problems,such asdigital signature handwriting writing feature point selection problem,distinct and separate from print camouflage signature handwriting problems and in the actual process of identification of test material and sample selection problem;The fourth part is combined with the former three parts,mining of digital signature handwriting identification of writing still exist deficiencies,including its scientific nature,the actual operation on the possibility and the method of inspection is a better choice,etc.,on how to perfect the digital signature handwriting identification of several aspects of the proposal,consider using electronic data or introduce a new appraisal model of evaluation criteria,considering the feasibility of different methods,in the hope of the improvement of the follow-up system,method of innovation and the development of science and technology to a new impact on digital handwriting signature handwriting identification,promote the development of this kind of appraisal,To make up for the defects in the field of identification;In addition,this article only the study of digital signature handwriting written under normal circumstances,after the camouflage,imitating the writing in this way will appear in the actual life,so also hope to through the normal digital signature handwriting writing research,to expand the digital signature handwriting written under other circumstances research foundation.
