Design and Implementation of the Drug Traceability System Based on Block Chain Technology

Abstract

AbstractDrug traceability is a system that supervises the production and circulation of drugs through the electronic supervision system of drugs. If problems occur, they can be traced back to the system. Since the development of the society, drug use safety is walking into people’s concern and becomes a hot spot in people’s life. This article is based on the alliance block chain Hyper ledger Fabric technology, combined with existing drug production, warehousing, logistics, and sales models for research, and proposes the drug anti-counterfeiting traceability system implementation plans, with the help of distributed ledgers, smart contracts, and consensus Mechanisms and other technologies write drug data into the block chain to ensure the safety of drug information. It is also for consumers, quality inspection agencies and the State Food and Drug Administration to trace the source of drugs. Using block chain technology, during the entire process of drug supply, various related information of drugs is automatically recorded and stored, and a traceability and anti-counterfeiting system is established for the whole process from production and processing to sales, so as to solve problems such as the source and safety of drugs, and guarantee The quality and safety of medicines, while realizing decentralized, secure, and non-tamperable medical data sharing, contribute to the shared medical resources in the context of my country’s medical big data.KeywordsDrug traceabilitySecurityBlock chain
