<p>The conventional medicine supply chain (MSC) involves various intermediaries, such as manufacturers, distributors, retailers, consumers, and healthcare providers, to ensure the effective and safe delivery of medicines. All intermediaries store, manage, and share real-time updates over the Internet, leading to various security and privacy issues affecting patient safety and health. It poses data breaches, counterfeit medicines, fraudulent entry, and third-party risks that compromise the authenticity, confidentiality, privacy, and integrity of MSC data. To tackle this, the pharmaceutical industry adopted blockchain technology. The public blockchain provides tamper-proof storage, transparency, security, and traceability, but often fails to provide scalable and enterprise-level solutions for the MSC. Later, private blockchain provides a channel approach that ensures data privacy at the channel level, but is often limited to keeping private data in the same channel. To address the aforementioned issues, we proposed a private data collection (PDC)-enabled MSC framework, where we adopted PDC of Hyperledger Fabric to keep data confidential and private from organizations on the same channel. Moreover, the proposed framework provides read-and-write access control rights to specific organization members, MSC, improving the system’s data privacy. Additionally, the proposed framework uses a single channel to access the data based on the organization’s access rights, which reduces multiple-channel computation overhead and improves the system’s scalability. We measured the performance of the proposed framework using transaction latency (0.03 s) and transaction throughput (704.3 tps) for different asset sizes, numbers of transactions, and clients using Hyperledger Caliper.</p>
