And simulating the traditional paper stamping operation, storing the seal picture into a WORD file or an HTML webpage by user operation, and then printing and storing. This stage belongs to the germination period of the development of electronic signature technology.
The seal and signature separation stage is to sign the file to be protected by using a digital certificate, so that the file content is ensured not to be modified, the file can be transmitted and stored with confidence, and the seal picture is only used for showing and has no correlation with the signature. Electronic signature manufacturers such as point gathering, gold grid and the like begin to use digital signature technology to carry out signature protection on files.
