Blockchain Based Patient Centric Medical Records Sharing With Privacy Preservation

Abstract

Individual health records (IHRs) hold paramount significance for individuals, serving as vital tools for the management and oversight of their medical data. Through electronic platforms, IHRs empower patients by granting them authority over their health information, thereby revolutionizing the conventional dynamics of the healthcare provider-patient relationship. Nonetheless, existing systems for managing IHRs face obstacles in providing patients with dependable, trackable, and secure control over their medical records, potentially compromising their authenticity and precision. Furthermore, the prevalent centralized methods of IHR management hinder the seamless exchange of medical data and introduce the risk of a singular point of failure.To address these challenges, a proposal is presented to utilize Ethereum blockchain-based smart contracts, providing patients with decentralized, immutable, and transparent management of their medical data. This solution also incorporate the decentralized storage feature of interplanetary file systems (IPFS). These integrated components collaborate effectively to securely access, store, and exchange patients’ medical information, with the overarching goal of enhancing the integrity and security of patient-controlled health records.
