Blockchain and Hyperledger Framework Based on Secure Application and Accurate Medical Reconciliation in Healthcare System

Abstract

A new way of handling secure medical data is introduced through the integration of blockchain and Hyperledger Fabric in the healthcare sector. To ensure data privacy, interoperability, and ac- curacy in medical reconciliation, this research proposes an Electronic Health Record system based on blockchain. The solution is secure and accessible while allowing for safe patient-centered data sharing by utilizing smart contracts and cryptographic methods. The system employs Ethereum for execution of smart contracts, IPFS for decentralized storage, and Hyperledger Fabric for permis- sioned access. The proposed paradigm enhances security and offers robust protection against online attacks using post-quantum encryption and zero-knowledge proofs. The experimental study proves enhanced transaction efficiency, reduced latency, and higher trust among healthcare stakeholders. The research focuses on how blockchain can revolutionize healthcare by facilitating security, trans- parency, and seamless interoperability among organizations
