Blockchain based Privacy Preservation Supply Chain Framework for Healthcare 5 0

Abstract

In the digital era, technological advancements empower the healthcare industry to deliver quality care to their patients. It promotes preventive measures and improves patient safety, health, and well-being. Healthcare 5.0 incorporated emerging technologies to enable efficient drug development, precision medicine, clinical trials, and supply chain management, enhancing healthcare outcomes and benefiting patients in their health. Healthcare 5.0 coheres with the medicine supply chain (MSC) to strengthen the process of medicine delivery. This alignment streamlines the logistics journey of medicines from manufacturer to retailer, ensuring the availability of essential medicines for a patient. MSC is a complex process expanding across various organizations, offering a seamless flow of medicine delivery. The complexity of the MSC system introduces inefficiency, such as fake information about medicines, limited data provenance, delay in medicine delivery and lack of transparency between different intermediaries. Moreover, these inefficiencies are resulting in the delivery of counterfeit medicines. The research community has used different security solutions to address this issue, including multi-factor authentication, mutual authentication, key exchange, and encryption algorithms to protect MSC data from malicious users. The aforementioned security solutions used centralized servers to manage credentials and key information. This centralized server stored data in a centralized database, which increases the possibility of data loss, single node failure, and data tempering, leading to security and privacy issues. With this concern, the researcher identified blockchain as a prominent solution to this issue. newlineHealthcare industry adopted blockchain for MSC. A blockchain-based MSC schemes ensure security and privacy but fails to prove the validity of MSC data before storing it in the blockchain. Most of the existing blockchain-based MSC schemes ensure only data security. However, due to open and transparent nature of public blo
