A Blockchain-Based Approach for Drug Traceability in Healthcare Supply Chain

Computer Engineering

Drug traceability system is essentially important for public drug security and business of pharmaceutical companies, which aims to track or trace where the drug has been and where it has gone along the drug supply chain.Traditional centralised server-client technical solutions have proved unsatisfactory due to poor data integrity, privacy, system resilience, and adapt-ability.Counterfeit medications are becoming a more serious problem in the healthcare industry, posing serious hazards to society. The challenge of tracing medications throughout the pharmaceutical supply chain is tough. The management and sharing of health records is another important challenge in the fight against counterfeit medications in healthcare systems. E-health records’ security is a major concern since they are vulnerable to threats to confidentiality and integrity.In this paper, we offer an Ethereumblock chain-based approach for efficient product tracing in the healthcare supply chain that uses smart contracts and decentralized off-chain storage. The smart contract ensures data provenance, eliminates the need for middlemen, and provides all parties with a safe, immutable transaction history. We offer the system architecture as well as the detailed algorithms that regulate our proposed solution’s functioning principles.
