Problems solved by technology

However, the traditional silo-structured smart city cannot well realize the mutual access and efficient utilization of data and resources between different departments; if data sharing is realized through centralized and unified management and control, the data security will be greatly reduced, and the data will be vulnerable to Tampering, cannot guarantee trusted access and privacy protection of data between different departments, and even the problem of data tampering may occur

Embodiment 1

[0044] A cross-departmental data sharing system based on blockchain technology, such as figure 1 As shown, it includes query server 1, sorting node 2 and multiple departmental storage centers, each departmental storage center includes a data collection module, at least one data processing server 4, and one distributed storage system 5.

[0045]Sorting node 2 is used to sort all transactions of stored data. The sorting node 2 is a cluster composed of a group of Order nodes. There is a synchronous consensus mechanism between the sorting nodes 2. In this embodiment, the sorting node 2 is composed of three nodes, Order1, Order2, and Order3. It is a computer cluster. Each Nodes are deployed on different servers, which can increase the reliability of the system. If an Order node stops working, other Order nodes can still sort.

[0046] The data acquisition module is connected to the data processing server 4, the data processing server 4 is respectively connected to the distributed ...

Abstract

The present invention relates to a cross-departmental data sharing system and method based on block chain technology. The system includes a query server, a sorting node, and multiple departmental storage centers. In each departmental storage center, a data acquisition module is connected to a data processing server, and the data The processing server is connected to the distributed storage system and the query server respectively, and the distributed storage system is connected to the query server; the data processing server acts as the peer node of the blockchain, and the sorting node transmits information to the storage centers of each department through the message channel. Compared with the existing technology, the present invention uses blockchain technology to directly store structured data on the chain, which can ensure that the data will not be tampered with. The hash value verification can also be traced, which further limits the behavior of tampering with the data and improves the security and credibility of the data sharing system.

Description

technical field [0001] The present invention relates to the field of data sharing, in particular to a cross-departmental data sharing system and method based on block chain technology. Background technique [0002] With the continuous advancement of science and technology, more and more attention has been paid to the construction of smart cities. To put it simply, the construction of smart cities is to combine traditional industries with electronic information technology, and then connect and integrate the city's systems and services to improve The efficiency of resource operation, optimize urban management and services, and improve the quality of life of citizens. At the same time, with the rapid development of the next-generation technologies of the Internet of Things, cloud computing, blockchain, and mobile Internet, smart cities are gradually evolving into a new generation of smart cities with trusted sharing, privacy protection, and interconnection capabilities. [000...
