Electronic signature storage and verification method and device

Abstract

The embodiment of the invention relates to the field of electronic signatures, in particular to an electronic signature storage and verification method and device, and is used for solving the problemsthat in the prior art, storage of associated information of electronic signature data and electronic signature data is prone to errors, and the electronic signature data verification efficiency is low. The method comprises the steps of obtaining electronic signature data and associated information of the electronic signature data, wherein the associated information is used for providing an extended function when the electronic signature is used; assembling the electronic signature data and the associated information into an electronic signature according to a preset data format of the electronic signature, wherein the preset data format of the electronic signature comprises an expansion field and an electronic signature data field, the electronic signature data is arranged in the electronic signature data field, and the associated information is arranged in the expansion field; and storing the electronic signature in the target file. According to the embodiment of the invention, the problems of easy storage error and low electronic signature data verification efficiency caused by decentralized storage in the prior art are solved.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic signatures, in particular to a method and device for storing and verifying electronic signatures. Background technique [0002] The electronic signature uses image processing to transform the electronic signature operation into the same visual effect as the paper document sealing operation; at the same time, the electronic signature technology is used to ensure the authenticity and integrity of the electronic information and the non-repudiation of the signer. Electronic signatures make the security of signatures better guaranteed, and it is convenient for stamping in different places and joint stamping, which saves office costs and improves office efficiency. It has been widely used in recent years. [0003] At present, in the actual electronic signature process, due to the different degrees of understanding of electronic documents by R&D personnel, the electronic signature data...
