Cold chain data tracking method and system based on Internet of Things and block chain

Abstract

The invention discloses a cold chain data tracking method and system based on the Internet of Things and a block chain, and is applied to the technical field of traceability. Firstly, an alliance chain is utilized to exclude nodes without permission, so that the data security is ensured; then verifying whether the nodes are legal nodes, if the nodes are legal nodes, further verifying the authenticity of the data, and if the nodes are illegal nodes, removing the alliance chain; and finally, real data being capable of forming a complete traceability track through information represented by the commodity traceability code and the digital certificate, sharing the traceability track on the alliance chain. Each node can look up the traceability track, and unreal data can be marked.

Description

Technical field [0001] The present invention relates to the technical field tracing, more particularly, to a composition based on cold chain block chain networking and data tracking method and system. Background technique [0002] Data traceability is defined as the original data recorded in the entire life cycle (the generation, propagation to die) information and evolution Evolution processing contents. In our view, DataProvenance should be translated into a "data traceability," it emphasized a chase tracing the source of the technology, to reproduce the history of the state and evolution of data according to tracking the path to achieve traceability data historical archives. [0003] With the development of traceability technology, more and more loopholes beginning to show, we all know data for the purpose of traceability is to ensure data integrity, thereby ensuring the legitimate rights and interests of consumers, but the current data record or traceable mainly paper radio f...

Problems solved by technology

[0003] With the development of traceability technology, more and more loopholes are beginning to be revealed. We all know that the purpose of data traceability is to ensure the authenticity of the data and thus protect the legitimate rights and interests of consumers. However, at present, data traceability mainly uses paper records or Recording with radio frequency technology, both of which have the risk of tampering, cannot guarantee the authenticity of the data in the circulation process, and naturally cannot achieve the fundamental purpose of data traceability
