Abstract

The vulnerabilities inherent in centralised storage systems highlight the significant issues concerning the security and privacy of Patient Health Records (PHRs) within the healthcare sector. Such system breaches put patients and healthcare practitioners in difficult ethical and legal situations in addition to compromising the privacy of sensitive health data. Furthermore, there is a lack of mutual trust between parties in the existing practices of exchanging patient data across different healthcare organisations, which leads to insufficient security measures and privacy breaches. The goal of this research is to solve these challenges by presenting a novel solution called PHR-NFT, which uses blockchain technology—specifically, Hyperledger Fabric and Non-Fungible Tokens (NFTs)—to establish a safe and transparent framework for the management of PHRs. Building a transparent and safe system that protects patient privacy and enables effective communication between healthcare practitioners and patients is made possible by the solid framework offered by the Hyperledger Fabric architecture. The PHR-NFT's capacity to link different healthcare ecosystem players through a permission-based process is one of its primary features. Medical professionals can temporarily access patient records through NFTs, allowing for smooth communication and giving patients ownership over their health information. The feasibility and efficiency of the PHR-NFT scheme are demonstrated by the results of a performance evaluation that focuses on transaction latency, throughput, and security. The significance of transaction rate control in maximising network performance is demonstrated by evaluating network performance over a range of chain code activities. DoS Attack simulation also evaluates the system's ability to withstand high transaction loads, providing information about order service availability and system resilience. The study contributes to the expanding body of knowledge regarding blockchain-based healthcare systems by providing useful information to academics, medical professionals, and legislators.
