Industrial product supply chain traceability method and system based on Internet of Things and block chain

Abstract

The invention discloses an industrial product supply chain traceability method and system based on Internet of Things and a block chain. The method comprises steps: S1, a raw material source, and processing, packaging, logistics, selling and consumption behaviors of an industrial product are regarded as participating nodes of the block chain, and an acquisition device of the Internet of Things isused to carry out data acquisition on the participating nodes; S2, the acquired industrial product information is sent to a block chain data storage processor through the Internet of Things; and S3, the block chain data storage processor distributes security keys to the participating nodes of the block chain, the industrial product data with the security keys acquired are broadcasted to a sub block chain of each participating node, and a third party acquires related data information of the industrial product through accessing the block chain module. The invention aims at providing a method anda system for realizing industrial product supply chain traceability based on the Internet of Things and the block chain technology, information of each step of the industrial product can be ensured to be true, and traceability is facilitated.

Description

technical field [0001] The present invention relates to a traceability method of industrial product supply chain based on Internet of Things and block chain. The present invention also relates to a system of traceability method of industrial product supply chain based on Internet of Things and block chain, which belongs to the field of communication technology and network application technology field. Background technique [0002] With the improvement of people's income level and the change of consumption concept, the quality and safety of industrial products have attracted more and more attention from consumers. However, the quality situation of China's industrial products is becoming increasingly severe, and the quality problems of industrial products involve all links in the supply chain, including raw material suppliers, producers, and sellers. [0003] In order to solve the quality and safety problems of industrial products, the supply chain of industrial products has ...

Problems solved by technology

However, the traceability system based on the Internet of Things relies on the agent communication mode or the server / client mode. All devices need to be verified through the connection of the centralized cloud server. Factors such as disasters and hackers cause data damage, loss, and tampering, so it is difficult to achieve effective traceability and lack of credibility
