Digital Health with Digital Trust
A permissioned-blockchain architecture for health-data exchange, consent, privacy, and interoperability.
MY ROLE
Research lead and enterprise architect for permissioned blockchain, consent flows, and governance design.
THE DECISION
How can healthcare organizations share trusted records while preserving access control, patient consent, and regulatory boundaries?
APPROACH
- Designed a Hyperledger Fabric permission model
- Separated on-chain proof from off-chain clinical data
- Mapped tokenization, identity, consent, and access controls
- Considered interoperability, PDPA, and HIPAA requirements
EVIDENCE & DELIVERABLES
- 10-page architecture summary (sanitized excerpt)
- Supporting technical research collection in private archive
- End-to-end proposed data and governance flows
