BLOCKCHAIN FOR SECURE AND INTEROPERABLE HEALTH DATA EXCHANGE

This paper explores the novel application of blockchain technology for enhancing security and interoperability in healthcare data exchange, aligning closely with current advancements and demands in healthcare technology and secure digital systems. Blockchain’s decentralized and immutable ledger offers a transformative solution to pressing issues in healthcare data management by ensuring robust data privacy, real-time interoperability, and patient autonomy across diverse health information systems. Unlike traditional centralized approaches, blockchain enables secure, auditable, and patient-centered data exchanges, which reduce administrative barriers, enhance trust among stakeholders, and allow seamless cross-organizational data flow. Our research compares blockchain-enabled healthcare systems with existing data exchange frameworks, revealing blockchain’s unique strengths in minimizing data inconsistencies, ensuring tamper-proof record keeping, and offering cryptographic security for sensitive health information. The study includes a simulation of health data exchange using a blockchain model, highlighting its advantages in tracking real-time updates, preventing data breaches, and improving interoperability. This paper contributes significantly to health data security and interoperability by providing a framework for scalable, secure health data exchange and demonstrating blockchain’s potential to address key barriers to data integration in healthcare. Through a detailed examination of current applications, this research underscores blockchain’s role as a revolutionary tool in secure, interoperable healthcare data systems, paving the way for future innovations and regulatory frameworks.
