Abstract

The embodiment of the invention provides a method and device for binding an impression and a signature original text and a storage medium. In some embodiments of the invention, firstly, electronic equipment receives a signature original text sent by application equipment; abstract operation is performed on the signature original text to generate a plurality of byte abstract values corresponding tothe signature original text; then, the electronic signature associates the byte abstract values with pixel blocks contained in an impression corresponding to the signature original text, an association relationship between the signature original text and the impression is established, and an association result is obtained; according to the method for binding the impression and the signature original text, the impression is prevented from being stolen, the safety performance of the electronic signature is high, and the user experience is good.

Description

technical field [0001] This application relates to the field of electronic signatures, in particular to a method, device and storage medium for binding stamps and original texts of signatures. Background technique [0002] Electronic signature is a form of expression of electronic signature. It uses image processing technology to convert electronic signature operation into the same visual effect as paper document sealing operation. At the same time, electronic signature technology is used to ensure the authenticity and integrity of electronic information and Non-repudiation of the signer. [0003] According to the above definition, the current electronic signature technology focuses on using electronic signatures to protect the validity of electronic documents, but ignores the protection of electronic signature document impressions. As a result, the impression in the electronic document can be easily "taken away" and used by others, resulting in potential safety hazards. ...
