Embodiment Construction

[0018] In order to make the purpose, advantages and technical solutions of the present invention more clear, the present invention will be further described in detail through the following specific measures in conjunction with the accompanying drawings.

[0019] Such as figure 1 , 2 As shown, the present invention mainly includes the following specific contents.

[0020] 1. Construction of adaptive data flow rules based on blockchain contracts

[0021] Data agents are preset in the system of each stage of the multi-data processing stage of the intelligent manufacturing supply chain to realize data sharing and interaction in the multi-data processing stage of the supply chain. The multi-data processing stage includes product development and design, production and manufacturing, Operation management, sales service, customer service, etc. An adaptive data flow rule builder based on blockchain smart contracts is built into each data agent. Based on the construction mechanism o...

Abstract

The present invention provides a blockchain-based cross-domain data security sharing management and control method in the manufacturing industry, which realizes fine-grained access and sharing of enterprise data under multi-service access. First, through the adaptive data flow rule builder based on blockchain smart contracts, the cross-domain data of the manufacturing industry based on reasonable path pre-analysis (such as product design data, production planning data, manufacturing process data, business management data, sales market data, equipment operation and maintenance data, customer data, etc.), and supports the dynamic path adjustment of the flow rule graph. Secondly, with the help of the data flow autonomous decision-making execution center of the blockchain smart contract, the data flow rule diagram is obtained according to the pre-analysis, and the compliance of the flow direction is judged before data sharing, effectively blocking unauthorized data access and sharing.

Description

technical field [0001] The invention belongs to the field of secure access to multi-entity data in a manufacturing supply chain system of information security, and specifically relates to a method for securely sharing and controlling cross-domain data in the manufacturing industry based on blockchain. Background technique [0002] With the rapid development of 5G, artificial intelligence, big data, blockchain and other technologies, the supply chain process control for intelligent manufacturing is closely integrated with various business fields throughout the product life cycle, and needs to be closely integrated with product R&D, design, manufacturing, and operation. Management, sales service, customer service and other multi-stage and multi-business domains are combined to integrate cross-stage, cross-domain and multi-source data of manufacturing enterprises to form a cross-enterprise data management and control system, and to solve the problem of information islands betwee...
