There is no unified expression for the concept of electronic signature. A typical example is the UNCITRAL Model Law on Electronic Signatures and its guide: "Electronic signature refers to the data contained in, attached to or logically associated with a data message in electronic form, which can be used to identify the signer related to the data message and show that this person approves the information contained in the data message."

At present, some scholars divide electronic signatures into three categories: broad sense, narrow sense and compromise (reinforcement): "The so-called broad sense electronic signature refers to electronic signatures including various electronic means. This concept focuses on the purpose and function of electronic signature, but there is almost no regulation on the technical methods used in electronic signature. Any electronic form of data attached to or logically associated with data telecommunications can be used as an electronic signature.

It refers to an electronic signature that can achieve the same function as the traditional signature after a certain security application. "(Note) This concept is a compromise between the broad and narrow concepts of electronic signature, which emphasizes the effectiveness of electronic signature, but it is as general as possible in its specific implementation form to cover various technical means and reserve space for the legal development and application of electronic signature technology.
