Abstract

The invention discloses an electronically signing method and an electronic signature verification method based on dynamic passwords. According to the electronically signing method, electronic documents to be signed electronically are signed electronically on the basis of dynamic password private keys generated by personal information of a user, and according to the electronic signature verification method, electronic signature verification is performed on received signature data on the basis of the reserved personal information of the user. The electronically signing method and the electronic signature verification method based on the dynamic passwords are easy to manage, convenient to operate, low in manufacturing cost and convenient for the user to use.

Description

technical field [0001] The invention relates to the field of electronic signatures, in particular to an electronic signature method based on a dynamic password and an electronic signature verification method. Background technique [0002] Electronic seal technology uses advanced digital technology to simulate traditional physical seals. Its management and use methods conform to the habits and experience of physical seals. The electronic documents stamped by it have the same appearance, the same effectiveness and similar usage. An electronic seal is not simply a seal image plus an electronic signature, but its use and management conform to the habits and experience of physical seals. The electronic documents stamped by it have the same appearance as paper documents, and the way of use is quite different from that of paper documents. degree of similarity. It can be seen that electronic seal verification is actually a form of electronic signature. Image processing technology ...
