Research On The Elderly Signature Handwriting Examination

According to the sixth census report of the China Population Census Network,there are 3,197,470 people aged over 60 at the moment,accounting for 12.01% of the country's population.China is gradually entering the stage of aging population.Population aging has an impact on all aspects of social life.In the areas of contract disputes,medical infringement disputes,inheritance disputes,etc.,cases involving the identification of seniors' signatures gradually increased.With the increase in the number of old handwriting examinations,the parties often controversial about the changing signatures of older persons,especially the elderly.People's memory declines significantly,and it is easy to negate the signature handwriting that was previously unclear or forgotten in the signature handwriting of the past.This is prone to disputes over handwriting identification and even questioned the handwriting identification opinions.This requires that handwriting identification pays attention to the study of handwriting identification in the elderly in theoretical research and practice,explores the identification of handwriting signatures that have undergone changes in physiology,psychology,and pathology,and accurately grasps the regularity of the stability and change of handwriting identification characteristics in the elderly.,improve the scientific reliability of such handwriting identification.This article mainly discusses the signature identification of seniors through four parts.Starting from the introduction of the basic situation of signature verification for the elderly,the elderly handwritten signatures were collected to perform statistical analysis on the handwriting signatures of the elderly,and the handwriting signatures of the elderly were compared with other signature handwriting to propose the elderly.The main points of signature handwriting identification hope to provide the basis for the actual identification work.The first part of the article is the foundation of the entire article,mainly introduces the characteristics of the signature handwriting,the current status of research on the handwriting of the elderly in China,the significance of research,and the scientific basis for the elderly handwriting signature identification.As an important part of handwriting identification,signature handwriting has the characteristics of distinction and other handwriting.These characteristics not only provide the basis for identification of signature handwriting,but also increase thedifficulty of signature handwriting identification to some extent.At present,there are relatively few monographs in the field of elderly person signature handwriting research.At present,China is in an ageing state.The identification of elderly handwriting signatures has a large demand in the actual appraisal work,so it is necessary to make signature signs for the elderly.Specialized research.The reason why the handwriting signatures of the elderly can be identified is also based on certain scientific basis.This article mainly focuses on the specificity of writing habits,the relative stability of the particularity of writing habits,and the reflection of writing habits.The second part of the article mainly introduces the influencing factors of changes in handwriting signatures of the elderly,including physiological factors,pathological factors,and other factors.After entering the old age,with the debilitating body function and the influence of the disease,the signature handwriting of the elderly will also change with certainty.At the same time,the interests,hobbies,occupations,etc.of the elderly people's lives will also produce a certain degree of signature handwriting impact.The third part of the article mainly focuses on the characteristics of the general characteristics(size of font,strength of writing,degree of coordination of writing speed)and details of features(from the perspective of age and educational level).The statistical analysis of stylus characteristics and bending characteristics,and the analysis of statistical data to analyze the value of characteristics in the signature signatures of the elderly,and the characteristics of high stability and high specificity and specificity in elderly handwriting signatures The analysis and introduction,finally through the above-mentioned statistical analysis,put forward in the actual forensic appraisal,the appraisal key points of middle-aged and old-aged signature handwriting identification,hoping to provide theoretical guidance for the actual appraisal work.The fourth part of the article mainly introduces the difference between the elderly handwriting signature and the imitation signature handwriting and the left hand disguised signature handwriting.There are many similarities between old-age signature handwriting and imitation signature handwriting and left-hand disguised signature handwriting.In practice,there is often a situation where confusion or even confusion arises between the two,but it is essentially different.The article makes a detailed distinction.
