Legal analysis: there must be a difference between imitation handwriting and authenticity. When imitating other people's notes, imitators often pay attention to the basic writing form of the imitated handwriting, Lian Bi's action structure and other microscopic characteristics, especially the dynamic pen pressure characteristics. It is difficult to fully grasp the use of this feature to judge whether the signature of a sample is written normally or imitated.
Legal basis: Article 224 of the Criminal Law of People's Republic of China (PRC) refers to the act of fabricating facts or concealing the truth to defraud the other party's property in the process of signing and performing a contract for the purpose of illegal possession.
