Hyperledger Fabric-Based Blockchain Framework for Secure and Interoperable Healthcare Record Management

Abstract: Patient mobility and specialized healthcare services have increased the issues associated with managing a distributed electronic health record. Traditional electronic health records systems lack the robustness for confidentiality, integrity, or data interoperability even with the support of standards like Fast Healthcare Interoperability Resources and Health Level 7. Most data- sharing methods nowadays are push, pull, and view, which normally give poor security and standard audit trails that may offer potential dangers of data shattering or unauthorized access. This paper introduces a decentralized healthcare record solution utilizing Hyperledger Fabric, a permissioned blockchain framework, to address those issues. The proposed system would leverage the secure and non-modifiable storage of the blockchain while enhancing interoperability among healthcare providers as well as protecting patient anonymity through the use of smart contracts and controlled access. Hyperledger Fabric's architecture, built on the idea of trust among network members, does not require centralized surveillance but instead is supported through Certificate Authorities and Membership Service Providers. This decentralization decreases the cost of the resources and ensures integrity, giving patients more control of their medical information.
