Block chain-based drug traceability method and device and medium

Abstract

The invention discloses a block chain-based drug traceability method and device and a medium. The block chain-based drug traceability method comprises the steps: auditing a to-be-uploaded intelligentcontract, and sending the to-be-uploaded intelligent contract passing the auditing to each node to form a drug traceability intelligent contract; obtaining drug information, associating the drug information with the drug traceability code, and uploading the drug information to the drug traceability block chain; receiving an access instruction and obtaining the drug information on the drug traceability block chain according to the drug traceability intelligent contract, wherein the access instruction comprises identifying the drug traceability code; and pushing the acquired drug information toan access terminal. The drug traceability block chain related to the drug traceability method is is tamper-proof and can retain the uniqueness of the drug information and the detection certificates and can accurately and quickly provide data such as materials in different states in the drug production, circulation and detection process to consumers in real time so as to realize the tracing of thewhole drug production process.

Description

technical field [0001] This application relates to the field of medical product information technology, in particular to a blockchain-based drug traceability method, equipment, and media. Background technique [0002] In recent years, the problem of counterfeit and shoddy medicines has been troubling the vast number of consumers, and many people have suffered greatly from it, and they hate counterfeit and shoddy medicines. However, there is still no effective way to prevent and control counterfeit and shoddy drugs, which can save consumers from losses, effectively supervise and trace the information in all aspects of drug production, circulation, and testing, and once fake and shoddy drugs are found, they can quickly retrospective accountability. [0003] When consumers buy commodities, especially medicines, they often worry about the authenticity, quality and standardization of distribution channels of medicines. Drug manufacturers also need to grasp the distribution of d...
