Healthcare Framework for Privacy-Preserving Based on Hyperledger Fabric

Abstract

The healthcare business deals with overly sensitive information that should be handled with care. Names, social security numbers, insurance numbers, addresses, and medical history are all stored in Electronic Health Records (EHRs). Patients, healthcare professionals, medical insurance companies, and research institutes all value such personal information. Patients and healthcare providers, on the other hand, face substantial privacy and security risks as a result of the public dissemination of this extremely sensitive personal data. When health information is transferred, EHR management systems necessitate the use of effective technology. Medical record storage systems are frequently exposed to typical security attack vectors due to current management techniques. As a result, we anticipate the need for new solutions to solve the security and privacy issues that private data poses in healthcare applications. Decentralized, anonymous, and secure EHR handling is possible with healthcare-focused blockchain systems. The needs for privacy and interoperability in healthcare data exchange are examined in this research, and a blockchain-based solution is offered. We used private blockchain technology to examine their suitability for healthcare applications in this paper. The permissioned blockchain structure of Hyperledger Fabric is used in the article. The proposed approach may effectively preserve patient details while maintaining anonymity. The findings of this study show that blockchain technology may be used to promote privacy while also improving interoperability in healthcare information management.
