Is handwriting identification a matter of on-site writing?

Handwriting identification usually analyzes and compares existing writing samples, rather than observing the writing behavior of the person being identified on site.

Handwriting identification is a technique that compares and analyzes writing samples to determine the authenticity, authorship, date, and other issues of a text, signature, or handwritten document. Note identification is mainly used in fields such as law, historical research, and personal identity confirmation.

When conducting note appraisal, the appraiser needs to first collect and organize relevant writing samples. These samples can be texts involved in the case, signatures, letters, diaries, paintings, and other written materials related to the text to be identified. The appraisers will then conduct detailed observation and analysis of these samples, including fonts, strokes, writing speed, pressure, character spacing, glyphs and other aspects.

The appraiser then compares the authenticated text with the writing sample. By comparing the similarities and differences between the two, appraisers can determine the authenticity or authorship of the text being authenticated. In addition, when conducting handwriting appraisal, appraisers also need to take into account factors such as the historical background, cultural background of the writing material, and the characteristics of the paper.

Handwriting identification can be accurate, but it can also contain errors. The experience and expertise of the appraiser, the quality and quantity of the texts being appraised, and the objectivity of the appraisal process all affect the accuracy of the results. Therefore, handwriting identification needs to be conducted by experts with extensive experience and expertise, and sufficient comparable samples need to be collected before identification.
