Embodiment Construction

[0054] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings.

[0055] The framework content of the present invention is as figure 1 As shown, the overall architecture of the present invention includes a data provider, a data owner, a data user, a server, and a blockchain. The following are the specific functions of each part:

[0056] (1) Data provider: The data provider acts as an authority and provides data for the data owner. The data owner first confirms whether the data from the data provider is correct. After confirming that it is correct, the data verified by the data provider can be downloaded to the local through the seal issuance system for sharing.

[0057] (2) Data owner: The data owner can upload files and choose the data to share with the data user.

[0058] (3) Data user: The data user c...

Abstract

The invention discloses a seal generation and verification method supporting subject and content authentication. The method comprises a seal generation stage and a seal verification stage. In the seal generation stage, a data owner uploads a file to a seal signing and issuing system, a shared file is generated through the seal signing and issuing system, a seal is generated and embedded into the shared file, and the shared file is encrypted and stored in a system server. In the seal verification stage, after logging in, the data user authorizes to use the private key of the data user, the seal issuing system uses the private key to decrypt the shared file for the data user to check, and the data user can request to obtain a file verification result and a traceability result. According to the method disclosed by the invention, high-strength security indexes such as non-tampering of the signature file content and non-imitation of the seal impression are realized by applying a digital signature technology and a block chain technology, so that the signature file has uniqueness, and illegal behaviors such as file counterfeiting and the like are avoided to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of electronic seals, and in particular relates to a method for generating and verifying seals supporting subject and content authentication. Background technique [0002] At this stage, the electronic seal is the product of the combination of the imprint of the traditional seal and the digital certificate. It is also an official seal in the form of electronic data and a personal seal with legal effect. Stamp (seal) on the document, based on domestic encryption technology to ensure the correctness, integrity and non-repudiation of the signed electronic document. [0003] However, among the patents that have been published so far, most of the electronic seal patents are generated with the seal itself as the main body or only with the content of the document. For example, the patent application "two-dimensional encrypted seal" with application number 200610038420 and the patent application "two-dimensional enc...
