Experimental Research On The Characteristics Of Imitated Handwriting Signature By Practice

With the improvement of technical level,handwriting appraisal has been professionalized and technically constructed and progressed.At the same time,the advancement of the technological level has led to the improvement of "counterfeiting" methods,and various "counterfeiting" methods have emerged one after another,resulting in the objective reality that the difficulty of pending cases is increasing.In criminal offenses,civil disputes,administrative litigation and other cases,there are a large number of actors who imitate handwriting in order to achieve the purpose of seeking economic benefits.Among all kinds of imitation handwriting,signature handwriting usually appears on IOUs,receipts,bills and contracts,and the number of characters is relatively small,and it is not difficult to obtain.It is undoubtedly the "severe disaster area" for imitating handwriting.Therefore,handwriting identification The work puts forward higher requirements.There are several types of imitation,such as copying,copying,recalling,and practicing imitation.The practice of imitation of signatures belongs to the category of practicing imitation,which means that the imitation of a person uses the imitation person’s signature as the “base pattern” through observation and perception.,Memorize the characteristics of the handwriting,and after a certain degree of consolidation exercises,after establishing a neural connection in the high-level nerve center of the cerebral cortex,repeat the forged signature handwriting.The practice of imitating handwriting has its own particularity,and the practice of imitating signature handwriting is a large number of criminal crimes and civil disputes.It has gradually become a key difficulty in handwriting identification in recent years.This article conducts a comprehensive and systematic research on Chinese practice imitating signature handwriting.Including the introduction,this article is divided into four chapters.The specific content is as follows:In the introduction part,firstly,the research background and research significance of practicing imitating signature handwriting are explained.Finally,summarize and sort out the current monographs and literature on the practice of imitating handwriting,clarify the current situation and researchable space of the practice of imitating signature handwriting in our country,and point out the direction for the research of this article.The first chapter is to practice the theoretical research of imitating signature handwriting identification,which is divided into two sections.The first section is an overview of the practice imitating signature handwriting;the second section is the scientific basis for practicing imitating signature handwriting identification,expounding the formation mechanism of practice imitating signature handwriting and the scientific basis for identification.The second chapter is the experimental research and analysis of practicing imitating signature handwriting,which is the key part of this article,which is divided into three sections.The first section is to practice imitating the signature handwriting experiment,explaining the purpose,significance,and experimental conditions and methods of the experiment;the second section is practicing the comparison and analysis of the similarity of imitating signature handwriting features,firstly,the collected experimental samples and data statistics are performed.The third chapter is to practice the research on the identification of imitated signature handwriting,which is divided into two sections.The first section is to practice imitating signature handwriting recognition,which mainly includes practicing the methods of accurate recognition of imitated signature handwriting and the requirements of identification conditions;the second section is practicing imitating signature handwriting inspection and comprehensive evaluation,focusing on the practice of imitating signature handwriting inspection materials and samples The inspection methods and main points of the handwriting,and the comprehensive judgment of handwriting characteristics are discussed.
