A REWARD MECHANISM FOR MEDICINE SUPPLY CHAIN THROUGH BLOCK CHAIN TECHNOLOGY

Abstract

The main issues with drug safety in the counterfeit medicine supply chain, are to do with how the drugs are initially manufactured. The traceability of right and active pharmaceutical ingredients during actual manufacture is a difficult process, so detecting drugs that do not contain the intended active ingredients can ultimately lead to end consumer patient harm or even death. Block chain’s advanced features make it capable of providing a basis for complete traceability of drugs, from manufacturer to end consumer, and the ability to identify counterfeit-drug. This paper aims to address the issue of drug safety using Block chain and encrypted QR(quick response) code security. Manufacturer generates an encrypted QR (quick response) code for the details and attaches the transaction to the block chain system. If any participants want details of drugs, then public key must be shared by that participant to the manufacturer. Manufacturer will encrypt the QR code and will send back to the participant. The QR code will be decrypted by the valid participant by their private key.
