Government affair data sharing system based on block chain

Abstract

The invention discloses a government affair data sharing system based on a block chain. The government affair data sharing system is provided with a use main body. The system comprises a system supervisor and a data provider, and the use main body, the system supervisor and the data provider are used as nodes to jointly construct a government affair data sharing chain. The method has the beneficial effect that the data catalogue is credible and evidenced, the authenticity and the security of the data are guaranteed by utilizing the characteristics of distributed storage, timestamps and non-tampering of the block chain; and data resource sharing is safe. The access permission of the data is controlled through the block chain gateway access control contract, and the data is processed throughthe sandbox security bin to prevent data leakage; privacy storage. In the data uploading process, data address directory uploading and data hash uploading are adopted, an uploading data plaintext isnot needed, the safety of data is guaranteed, and leakage is prevented.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a blockchain-based government affairs data sharing system. Background technique [0002] Blockchain technology is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is a distributed database system in which multiple nodes participate together. Blockchain is not a single technology, but a multi-technology integration As a result, using the blockchain to maintain a reliable and difficult-to-tamper ledger record can reduce trust risks and effectively reduce maintenance costs for all participants. If the data is to be stored in the blockchain, it must obtain the consensus of the participating parties. After the data is uploaded to the chain, it cannot be tampered with or forged. [0003] Most of the current government data storage is independently stored by each unit, and various data are stored separately in various...

Problems solved by technology

If the data wants to be stored through the blockchain, it must obtain the consensus of the participating parties. After the data is uploaded to the chain, it cannot be tampered with or forged

[0003] Most of the current government data storage is independently stored by each unit, and various data are stored separately in various commissions, bureaus, big data bureaus, and different agencies. The data volume is large, the data format is complex, and the data storage rules are not clear, so it needs to be queried , It is very inconvenient to use, and at the same time, each data storage point can edit and modify its own data at will, and the authenticity of the output data cannot be guaranteed
