Integration of Blockchain Solutions for SecureHealthcare Data Exchange

Abstract

Healthcare data management faces persistent challenges, including data breaches, unauthorized access, and fragmented storage across multiple institutions. Blockchain technology provides a decentralized, tamper-proof, and transparent framework for secure data exchange in healthcare systems. This paper explores the integration of blockchain solutions to facilitate secure, interoperable, and privacy-preserving healthcare data exchange. The study proposes a blockchain-based architecture that combines smart contracts, distributed ledgers, and cryptographic mechanisms to ensure data integrity, patient consent management, and controlled access. The methodology involves deploying permissioned blockchain networks, evaluating data throughput, latency, and scalability, and integrating interoperability protocols with existing healthcare information systems. Results demonstrate enhanced data security, reduced risk of breaches, and improved efficiency in cross-institutional data sharing. Additionally, the framework supports auditability, accountability, and compliance with regulatory requirements. This research highlights the transformative potential of blockchain in creating resilient, secure, and efficient healthcare data ecosystems.
