Despite significant improvements in healthcare innovations and administration, little has been done to address security threats such as data breaches or cybersecurity. To ensure the best services, healthcare authorities must manage healthcare data effectively—not just during or post-pandemic situations such as COVID-19, but also in their regular operations. Blockchain (BC) technology can be utilized to increase the security of healthcare data management. Healthcare providers may create a transparent, tamper-proof system for handling patient records, authentication, and access control by utilizing blockchain. We offer a general blockchain-enabled healthcare architecture for managing healthcare data reflecting various participant interactions. Our system connects all parties, including physicians, patients, governments, supply chains, and other healthcare practitioners, via the Ethereum network. The smart contract code development and testing were done on the Remix IDE platform. We have combined Hyperledger Fabric (HLF) and the InterPlanetary File System (IPFS) to provide decentralized storage. In addition to examining numerous safety concerns, we also compared our solution to other blockchain-based systems and offered a cost analysis of the various transactions it proposes. We have also demonstrated the benefits of using Blockchain for a secure and reliable healthcare system. We also highlight the existing challenges in adopting BC in healthcare data management, as well as potential future research directions, both in terms of deployment and real-world application.
