Electronic Health Records & Data Management using Hyperledger fabric in Blockchain

Abstract

Permissioned blockchain networks ensure safety and reliability by employing blockchain’s fundamental tenets, including the distributed ledger, smart contracts, and consensus. There is a potential for data privacy violations in the existing condition of patient data interchange across healthcare organizations if there is a lack of mutual trust. The introduction of blockchain technology has made it possible for healthcare providers to confidently share patient medical records. To ensure the safe and reliable transfer of patient information, a permission blockchain network built on the Hyperledger Fabric framework is proposed and implemented between patents and medical institutions. Blockchain’s effective management of EHRs is made possible by a Hyper Ledger Fabric network. Results from live deployments demonstrate that inaccuracies in data sharing between healthcare providers (such as hospitals, clinics, and public health agencies) are eliminated by using a blockchain based on the Hyperledger fabric. The accessibility of the network allows for the prompt, secure, and legally compliant transfer of patient information across organizations. By using smart contracts as chain code, the blockchain has enabled transparent and secure data exchanges while controlling access to private patient health information. Results indicate Hyper Ledger Fabric provides excellent functionality, security, and transaction privacy.
