Handwriting identification refers to the recognition and identification of handwriting formed by people through writing activities. People's writing habits are concrete and stable, which are reflected in handwriting. Through the inspection of handwriting, we can determine whether the handwriting in the document was written by several people or by one person, and use handwriting to identify the same person and verify the authenticity of the document.
When appraising, it is necessary to understand the relevant situation of the case, clarify the appraisal requirements, and check the handwriting material evidence and handwriting samples; Analyze and judge whether the handwriting is normal, whether there are changes caused by camouflage or other reasons; Choose stable characteristics that can reflect the writer's writing habits; Compare the samples with the features found in the samples, and find out the coincidence points and differences; Comprehensive evaluation of the reasons for the formation of coincidence points and differences; Make an appraisal opinion and make an appraisal book.
According to the characteristics and case of handwriting, accurately judge the change or disguise of handwriting characteristics and the reason and degree of change or disguise. If the handwriting proficiency of the sample is consistent, the writing level is adapted to the Chinese level, the strokes are natural, the stroke proportion is coordinated, and the writing action is regular, it can be considered as normal handwriting.
For example, the handwriting size and inclination are uneven, the writing speed is inconsistent, the stroke movement is unnatural, and the stroke turning is stiff, but the writing action is systematic to some extent, and the characteristics of the same character and stroke are basically the same, which indicates that it is due to objective reasons or other subjective factors except camouflage.
If the handwriting proficiency of the sample is inconsistent, the writing action is not systematic, the strokes bend intermittently, there are traces of pause and touch-up, the structure and shape of the characters are abnormal, and the skill of the movements is not commensurate with the Chinese level, it can generally be judged as disguised handwriting.
