Towards a Blockchain Assisted Patient Owned System for Electronic Health Records

Security and privacy of patients’ data is a major concern in the healthcare industry. In this paper, we propose system that activates robust security medical records as well enables interoperability exchange between different providers. The work proposes shift from patient’s electronic health being managed controlled by industry to patient-centric application where patients are control their data. aim research build an Electronic Healthcare Record (EHR) layered on Ethereum blockchain platform smart contract order eliminate need for third-party systems. With system, provider can search request consent access it. Patients manage which expedited across EHR Each stored peer-to-peer node ledger. proposed cross-platform compliant, it be accessed via personal computers mobile devices facilitates providers gathered unified format. framework tested private network using Ganache. results show effectiveness with respect security, privacy, performance interoperability.
