A Novel Blockchain Based Smart Contract System for eReferral in Healthcare: HealthChain

摘要

The privacy of Electronic Health Records is facing a major issue while outsourcing data in the cloud or sharing the records among stakeholders which includes the leakage of private and sensitive information to unauthorized entities. This research mainly focuses on introducing an efficient referral mechanism employing advanced smart contracts for the effective sharing of healthcare records between stakeholders in healthcare industry. This referral system is designed on a patient-centric model and are limited to authorized providers in the healthdata network. This system is built by employing Hyperledger Fabric as the permissioned blockchain utilising Hyperledger composer which visualizes the couchDB and Interplanetary File System as decentralised data storage are combined for efficient and secure big data sharing in healthcare sector.
