The identification of data message is mainly the identification of the generation, transmission and storage system of electronic signature data and data message. Examining the authenticity of data messages mainly includes:

(a) Reliability of the method of generating, storing or transmitting data messages;

(2) the reliability of the method to maintain the integrity of the content;

(3) the reliability of the method used to identify the sender;

(4) Other relevant factors.

If it is an electronic contract without a reliable electronic signature, it is very troublesome to authenticate it. It is necessary to carry out a series of authentication on the generation, transmission and storage system of electronic contracts to ensure the effectiveness of electronic contracts.
