Integrated Blockchain for Policy-Aware Health Data Exchange

A permissioned national health infrastructure for trustworthy records, accountable service delivery, and privacy-aware research collaboration

Client: Industry–Academia Collaboration (National Scope)

IEEE Access–published and Research Council of Norway–funded research on an integrated, policy-aware blockchain for secure health data exchange ( DOI: 10.1109/ACCESS.2023.3279724 ). This industry–academia collaboration combined Brain Station 23 PLC’s engineering expertise, AIUB’s academic and Bangladesh healthcare research, and the University of Stavanger’s international research contribution under the 5G-MODaNeI project. As first author, I helped design and evaluate a Hyperledger Fabric prototype featuring verified identities, policy-controlled access, auditable consent, and tamper-evident health records. 🇺🇳 🇪🇺 Global Research Scope: The architecture supports UN SDGs 3, 9, 16, and 17 through connected healthcare, resilient digital infrastructure, accountable data governance, and international research partnership. Its permissioned identity, access-control, integrity, and audit mechanisms provide a foundation for GDPR-aligned EU and HIPAA-aligned US pilot projects, subject to jurisdiction-specific privacy assessment, interoperability, and clinical validation.
