Method for collaboratively maintaining reliable data storage based on alliance block chain manufacturing industry department

Abstract

The invention relates to a method and system for a manufacturing department to cooperatively maintain reliable data storage based on an alliance block chain. The method comprises the following steps: S1, taking a plurality of protocol nodes as a center, and employing a distributed database and a Raft consensus technology to form an alliance block chain network; wherein each protocol node corresponds to at least one department and one distributed account book, and digital identity certificate management and data link management are carried out on the department by utilizing the protocol nodes; wherein the departments comprise a service department and a management department; s2, the management department manages application, verification, updating and revocation of the digital identity credentials of all the service departments; and S3, each service department logs in the corresponding protocol node by using the digital identity certificate, and performs data uplink and data query operation. According to the method provided by the invention, an alliance block chain technology is taken as a technical framework, and a new mode of data chaining, interaction and identity recognition management among departments is designed.

Description

technical field [0001] The present invention relates to the field of data interaction in the manufacturing industry, and in particular to a method and system for collaboratively maintaining reliable data storage for manufacturing departments based on alliance block chains. Background technique [0002] With the vigorous development of 5G and Internet of Things technologies, the wave of global manufacturing IT is coming. The combination of IT technology and the manufacturing field will turn every link and equipment in the production process into a data terminal, collect underlying basic data in an all-round way, and conduct deeper data analysis and mining, thereby improving efficiency and optimizing operations. Although IT-based technology has greatly enhanced the efficiency of industrial manufacturing, the introduction of IT technology into traditional industries will also create new data intelligence management issues. This is mainly manifested in 1) The data generated by ...

Problems solved by technology

[0006] In short, the existing technology has the following shortcomings and deficiencies: (1) The data generated by the manufacturing sectors serving "design, manufacturing, logistics, and after-sales" belong to independent organizations, and it is difficult for organizations to establish effective mutual trust methods so that mutual Data communication is an obstacle, and at the same time, how to design a specific inter-departmental data interaction mode to form a closed loop of data interaction is also a problem that needs to be solved at present; (2) The way that a single certification authority provides credit guarantee for data generated by various departments of the manufacturing industry, among which Inefficiency, and there is a risk of potential attacks and loss of trust authority
