License issuing security management system based on block chain

Abstract

The invention discloses a license issuing safety management system based on a block chain. The system is used for solving the problems that an existing license issuing department cannot perform auditing according to addresses submitted by users, cannot reasonably screen address pictures of corresponding registered users for collection and cannot reasonably allocate license data to corresponding nodes for storage. The system comprises a license data input module, a server, an issuing auditing module and a verification issuing module. According to the invention, the picture information is collected and audited for the address in the license data submitted by the registered user, and meanwhile, the blockchain license storage data is subjected to uplink processing through the data management module and is reasonably allocated to the corresponding node for storage; address processing value analysis is carried out on the registered users, so that the corresponding registered users can be reasonably selected to acquire picture information; the interchange range of the serial numbers is selected through the user values, so that interchange adjustment is carried out, and registered users can carry out reasonable interchange according to own conditions.

Description

technical field [0001] The invention relates to the technical field of certificate issuance management, in particular to a blockchain-based certificate issuance security management system. Background technique [0002] Government departments at all levels and internal agencies of each department are faced with the problem of effective certificate issuance management and unified authoritative certification in the process of realizing the docking process and data sharing. How to make the functions of the authority public and avoid the drawbacks caused by simplification and centralization of credit certification is a difficult point in the work of cross-regional coordination and data exchange and sharing. Blockchain creates value by creating trust. The blockchain creates trust, because the information and data stored in it cannot be tampered with and can be witnessed by the whole network, so that trust does not require the endorsement of a third-party organization, and can be ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing license-issuing department cannot review the address submitted by the user and can not reasonably screen the corresponding registered user's address picture collection and can not rationally distribute the license data to the corresponding node for storage problem, and propose a blockchain-based security management system for issuing licenses; the present invention collects and reviews the addresses in the license data submitted by registered users to facilitate the comparison of information for the staff of the license issuing department. At the same time, through the data management module, the blockchain certificate storage data is processed on the chain and reasonably distributed to the corresponding nodes for storage; through the analysis of the address processing value of the registered users, it is convenient to reasonably select the corresponding registered users for image information acquisition; through The user value selects the exchange range of the number, so as to adjust the exchange, so that registered users can perform reasonable exchange according to their own conditions;
