Government affair data cross-regional sharing method based on block chain and related components

Abstract

The invention discloses a government affair data cross-regional sharing method based on a block chain. A digital certificate system is applied to the field of data exchange. Government affair data ownership belongs to individuals, shared usage of personal government affair data related to privacy is authorized in a personal autonomous authorization mode, a problem that personal data privacy is invaded easily when a data use client uses the government affair data can be prevented, and effective and safe circulation of the government affair data among departments is guaranteed; meanwhile, in themethod, the block chain is used for tracing the generation, authorization and other processes of the digital certificate in the whole process; government affair data verification and effective extraction can be performed through the block chain regardless of whether the data use client is each department; the problems of government affair data islands and data barriers among the departments are solved, and effective cross-regional sharing of the government affair data is realized. The invention further discloses a data providing client, a certificate holder end and a government affair data cross-regional sharing system based on the block chain.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a blockchain-based cross-regional sharing method for government affairs data, a data providing client, a certificate holder terminal, and a blockchain-based cross-regional government affairs data sharing system. Background technique [0002] At present, due to the interconnection and interworking between various government departments at all levels, there is a need for data sharing of government affairs data at all levels of government and departments. At present, the cross-regional sharing of government affairs data is mainly based on the big data centers established by governments at all levels, and the big data centers directly collect The data of various government departments are aggregated and analyzed. [0003] And because some government affairs data involves personal data privacy and business secrets, sharing personal data without personal permission violates...

Problems solved by technology

[0003] And because some government affairs data involves personal data privacy and business secrets, sharing personal data without personal permission violates personal data privacy, and there may be corresponding legal risks; at the same time, the data interfaces of various government departments may not be uniform. Under the current situation, it is difficult for data among different government departments to be interconnected and interoperable, which seriously hinders data openness and sharing, resulting in government data islands and data barriers

[0004] Therefore, how to avoid government data sharing from violating personal privacy and at the same time break the data barriers caused by the inconsistency of data interfaces between various departments to achieve effective government data sharing is a technical problem that technicians in the field need to solve
