DrugBlock: An Advanced System to Secure Drug Supply Chain Using Internet of Things and Blockchain-Enabled Consumer Electronics

The growing consumer interest in product quality and originality has made the drug supply chain management system complex and critical. Moreover, fraudulent activities, such as drug contamination, have become global issues in the drug supply chain. Traditional centralized systems struggle to maintain transparency and traceability throughout the supply chain, often resulting in inefficiencies and vulnerabilities. Here, consumer electronics devices can be integrated with the ecosystem to extend the reach of the drug supply chain. In this paper, a solution for traditional drug supply chain systems is presented by using blockchain technology, Internet of Things (IoT), and consumer electronics. Here, blockchain supports to store drug records immutably, while keeping information transparent to all entities involved in the network. This proposed scheme is deployed over the Ethereum blockchain network and uses IoT technology to provide the key features of blockchain, such as drug traceability, security, and transparency. Here, smart contracts automate the entire process in the proposed supply chain network, and all the drug batch’s transfer details are stored on the blockchain network. The security analysis and performance analysis of the proposed scheme are performed to evaluate the efficiency of the proposed scheme over some existing schemes.
