Government affair chain data sharing method

Abstract

The invention discloses a government affair chain data sharing method. the method comprises: a second data sharing system firstly receiving the data sharing request; acquiring target shared data according to the data sharing acquisition request; judging the target shared data according to the authority of the first shared data system; the second data sharing system judges whether to agree to sharethe data or not, if yes, the second data sharing system judges whether to upload the hash value to the government affair chain or upload the original data and the hash value to the government affairchain according to the requirements of the user (the first data sharing system), and the first data system acquires the target sharing data by means of the authority. According to the method, the dataspace on the government affair chain is saved, and after the hash value is uploaded to the government affair chain, due to the uniqueness of the hash value, the locally stored data can be prevented from being tampered, so that the data security is improved. Through the government affair chain, the problem that standards cannot be unified during data sharing among the multiple data sharing systemsis solved, and data sharing among the data sharing systems is better achieved.

Description

technical field [0001] The invention relates to the technical field of data sharing, in particular to a data sharing method of a government affairs chain. Background technique [0002] At present, the common solution of big data architecture is: using open source big data components to realize functions such as data collection, data access, data processing, and structured storage of result data to meet business needs. Blockchain has a very broad application prospect in data storage and other fields because of its reliability, tamper-proof and digital advantages. However, the traditional blockchain also has shortcomings, such as: complete decentralization, full synchronous sharing of data, smart contracts, low-frequency processing, and the system needs to consume tokens. [0003] Now there is a government chain big data solution: the government chain and big data components are seamlessly combined, using the characteristics of the government chain, such as controllable shari...

Problems solved by technology

[0007] (3) The data cannot be tampered with: the hash algorithm encrypts the business data, and the generated string cannot reverse the original content, and the hash value is unique and cannot be tampered with

[0010] All data in the existing technology is shared on the blockchain, resulting in a large amount of data storage in the blockchain, which is prone to problems such as slow storage speed, incomplete stored data, and increasing system consumption; and The longer the system runs, the more data needs to be stored, which will eventually lead to the situation where the ordinary network bandwidth and storage space cannot be afforded by ordinary computers
