A blockchain-based trusted electronic certificate platform system and its authentication method

Abstract

The invention relates to a blockchain-based trusted electronic certificate platform system and an authentication method thereof. The blockchain-based trusted electronic certificate platform system of the present invention includes a government service client, an access service module and a blockchain. The government service client is used to store the certificate package, perform real-name authentication, and perform real-name authentication according to asymmetric encryption technology. Generate a user authentication public and private key pair; the access service module interacts with the blockchain and government service clients; the blockchain includes a certificate ledger and an event ledger. Its beneficial effects are: based on blockchain technology and asymmetric encryption technology, relying on real-name authentication and key authentication, the construction of an electronic certificate platform is completed. The blockchain-based trusted electronic license platform system is decentralized, the license file cannot be tampered with, and the data source can be traced; complete the binding of the license and the real-name subject, complete the communication and mutual trust between commissions, offices and bureaus, and realize less running away for users , the purpose of data errands.

Description

Technical field [0001] The invention involves the field of digital licenses, which specially involves a blockchain -based credit electronic certificate platform system and its certification methods, and is applied to "Internet+government services". Background technique [0002] At present, the electronic certificate sharing platform has been established in some areas, electronic paper certificates, and stored on the platform database. This method uses a third -party electronic certification service agency (generally CA) to provide authentication, electronic signatures and timestamp services. The data centered data is stored, and the certification is used to verify the certification. [0003] However, the current traditional electronic certificate system has the following problems: [1] Third -party institutions have strong dependence, institutional certification, electronic signature, timestamp, and electronic signatures depend on third -party certification agencies. [2] Data cent...

AI Technical Summary

Problems solved by technology

Although it uses blockchain technology to avoid the potential systemic risk of a single centralized organization, there are deficiencies in its system architecture, certificates, data storage methods, and use of certificates, and the complete original information of its certificates is uploaded to the chain. , the security is not good enough, and the amount of data on the chain is large, which requires a large storage space
