Drug traceability management method and system based on block chain technology

Abstract

The invention discloses a drug traceability management method and system based on a block chain technology. The method comprises the following steps of obtaining identity information of a plurality ofblock chain nodes and drug information supplied by each block chain node, associating a unique drug identification code for the drug information, and uploading the associated drug information to theblock chain node, authenticating the identity information of the currently accessed block chain node, and determining drug traceability information when the authentication is passed, according to a preset intelligent contract, constructing a drug circulation transaction between the authenticated block chain nodes, and updating the drug traceability state recorded by the block chain nodes, and in response to a query request for the drug traceability information, pushing the obtained query result to the access terminal. According to the drug traceability management method based on the block chain technology, what is guaranteed is that drug data cannot be tampered and are not prone to leakage, the full life cycle of production, circulation and detection of drugs is supervised, the authenticity of the data is guaranteed, and the drug traceability efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drug traceability, in particular to a drug traceability management method and system based on block chain technology. Background technique [0002] In recent years, medical accidents caused by counterfeit and shoddy drugs have attracted great attention from the state. The State Drug Administration is strengthening the supervision of drug authenticity, quality and distribution channels. Among them, reasonable drug traceability management methods are crucial to promoting drug supervision. is crucial. At present, some drug traceability methods have been introduced, but the existing methods often have the following shortcomings. On the one hand, in the existing traceability methods, the drug information data is stored on a centralized data platform, and the centralized data storage method is easy. Being attacked or destroyed leads to data leakage, making its stability and reliability impossible to guarantee;...

Problems solved by technology

At present, some drug traceability methods have been introduced, but the existing methods often have the following shortcomings. On the one hand, in the existing traceability methods, the drug information data is stored on a centralized data platform, and the centralized data storage method is easy. Being attacked or destroyed leads to data leakage, making its stability and reliability impossible to guarantee; in addition, centralized data storage cannot prevent data from being tampered with or falsified, and the authenticity and authority of data cannot be guaranteed, which further affects the Drug traceability efficiency and accuracy of information
