Yes.

Handwriting identification is a specialized technique for identifying writers based on their writing skills and habits, as well as their reflections in handwriting and paintings. The main task is to pass the handwriting identification test to prove whether the handwriting on the document and evidence is the handwriting of the same person, and to prove whether the handwriting on the document and evidence is the handwriting of a certain suspect. Handwriting identification can not only test normal handwriting, but also test handwriting that changes in writing conditions (including writing posture, writing tools, backing materials, etc.), deliberately disguised handwriting (including left-hand handwriting, ruler-stroke handwriting), imitation handwriting, and painting handwriting. When the same person writes with the same pen, the pen mark characteristics can also be used to enrich the basis for identifying the writer.
