DRUG GUARD: A BLOCKCHAIN BASED SUPPLY CHAIN MANAGEMENT (SCM) TO PREVENT COUNTERFEIT DRUGS

Abstract

The production and distribution of fake or counterfeit drugs is a critical and progressively basic issue in Bangladesh. Also, it causes a serious threat of pharmaceutical drugs. There are many reasons for drug counterfeiting, but one major reason is the imperfect supply chain. It is difficult to track over the drugs from manufacturing to distribution and the major requirement of the drug supply chain is the assurance of drug quality, together with efficacy and safety. Here we roposed a blockchain based network of drug supply chain management (SCM) from manufacturer to pharmacist where we provide tracking over drugs as well as visibility and the safety of sensitive drug information. The existing drug supply chain of Bangladesh manufacturers don’t know what happened with their drugs or which pharmacy is taking their drugs. But our proposed model ensures traceability so that manufacturers will be able to know which pharmacy is taking their drugs through the distributed network provided by blockchain. Our platform will provide a secure network where all participants can see all the transactions between other participants. All transactions between participants or users are recorded in the blockchain and other participants or users will be able to view the transactions history of participants. All blockchain transactions are also recorded in the database where we stored encrypted information of transactions and provide more security of our databases. Also encrypted QR (DAR number) will ensure that illegitimate participants will not able to make a copy of the information given by the manufacturer and will not be able to produce fake drugs by providing the same information. So, it will provide security of information about drugs as well as it will provide an encrypted QR code system so that illegitimate participants cannot know about the information of drugs.
