Blockchain Based Decentralized Authentication and Licensing Process of Medicine

Abstract

Counterfeit medicines are increasing day by day and these medicines are damaging the health of people. Drug Regulatory Authorities (DRAs) are trying to overcome this issue. Synchronized electronic medicine record can mitigate this risk. We proposed a decentralized Blockchain (BC) based medicine licensing and authentication system to stop production of counterfeit medicines. Our proposed system provides a convenient way to register medicines by manufacturers with DRA. Vendors will also be registered with DRA, they are intermediate who buy from manufacturer and sale to customers. Furthermore, every transaction between manufacturer and vendor will be saved to BC. We used Proof of Collaboration (PoC) as a consensus mechanism, the manufacturer deals with more vendors will have more mining p ower. DRA has a different department, i.e., Licensing Department (LD), regulatory Department (RD), and Quality Control Department (QAD). These departments perform many actions, which will be saved in the BC database. LD registers manufacturers and vendors, RD imposes rules and QAD makes random checks to test the quality of medicines. We also propose manufacturer profile scheme, QAD rates manufacturer according to its quality of medicines from the feedback of users. Moreover, we provide an interface to the users, through which they can check the authenticity of medicine. We compare results of traditional licensing system with BC based licensing system.
