Embodiment Construction
[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0031] Before introducing the embodiments of the present application in detail, relevant terms will be explained first.
[0032] Electronic signature: Electronic signature is a form of electronic signature. Image processing technology is used to convert electronic signature operation into the same visual effect as paper document sealing operation, and electronic signature technology is used to ensure the authenticity of electronic information. and integrity and non-repudiation of the signer.
[0033] Digital certificate: A digital certificate is a stamp or seal (or a signature added to a digital ID card) stamped on a digital ID card by a digital identity certification authority.
[0034] Die: Define the contour appearance information of the stamp, ...

The invention discloses a generation method, generation device, authentication method and authentication device of an electronic document with a stamp. The generation method of an electronic document with a stamp includes the following steps that: a digital certificate with a stamp image is obtained from a digital certificate issuing institution; the stamp image and corresponding seal information are written into a preset electronic document; and signature operation is performed on the electronic document through the digital certificate, so that a signature value can be obtained, and the signature value is written into the electronic document, so that an electronic document with a stamp can be generated. According to the generation method of the electronic document with the stamp of the invention, the stamp image is directly added into the digital certificate, so that the stamp image and the certificate become an indivisible integrated body; when a user verifies the seal, validity verification on the digital certificate and verification on the consistency of the appearance of the seal and the stamp information of the public key certificate can be completed with one step.
Description
technical field [0001] The present invention relates to the field of computer applications, and more specifically, to a method and device for generating electronic documents with stamps, and an authentication method and device. Background technique [0002] With the popularization of the Internet, the rapid development of various e-commerce activities and e-government activities, electronic signatures have been widely used in various fields, mainly including: sending secure emails, visiting secure sites, online bidding, online signing , Online ordering, secure online official document transmission, online payment, online tax payment, online stock trading, online shopping and online customs declaration, etc. [0003] The electronic signature itself is not actually a "signature", but is completed by using an asymmetric public key encryption system, and its operation method is a kind of mathematical operation in essence. Here, encryption refers to a technical process for hidin...
