MedHypChain: A patient-centered interoperability hyperledger-based medical healthcare system: Regulation in COVID-19...

Area of Science:

• Computer Science
• Health Informatics
• Blockchain Technology

Background:

• The COVID-19 pandemic highlighted limitations in medical data sharing and overwhelmed healthcare systems.
• Existing systems often prioritize institution-centered interoperability over patient-centered approaches.
• The need for secure, private, and accessible health data management is critical.

Purpose of the Study:

• To propose a novel privacy-preserving medical data sharing system using blockchain technology.
• To enable patient-centered interoperability (PCI) for improved healthcare data management.
• To address the challenges posed by pandemics like COVID-19 through enhanced data sharing.

Main Methods:

• Developed MedHypChain, a system based on Hyperledger Fabric with an Identity-based broadcast group signcryption scheme.
• Implemented a patient-centered healthcare system where patients control their health information on the blockchain.
• Utilized Hyperledger Caliper for performance analysis, evaluating latency, execution time, and throughput with up to 20 nodes.

Main Results:

• MedHypChain demonstrated confidentiality, anonymity, traceability, and unforgeability of medical data.
• The system successfully regularized for implementing a PCI healthcare system.
• Performance analysis showed efficient metrics, with the proposed scheme requiring minimal computation and communication costs.

Conclusions:

• MedHypChain offers a secure and efficient solution for privacy-preserving medical data sharing.
• The system supports patient-centered interoperability, enhancing data control and accessibility for authorized entities.
• MedHypChain provides superior security features, scalability, and access control compared to existing blockchain-based healthcare systems.
