Enabling Cross-Institution Health Data Sharing in Norway: EUDI Wallets, On-Chain Consent, and openEHR↔FHIR Translation
We present a GDPR-compliant digital health wallet architecture for Norway that enables secure, consent-driven health data sharing aligned with the European Health Data Space (EHDS) and EUDI frameworks. The system uses verifiable credentials, blockchain-based consent management, and zero-knowledge proofs to ensure privacy-preserving access control, while bridging openEHR and FHIR for interoperability. Evaluation demonstrates near real-time authorization and high semantic mapping accuracy, supporting national-scale deployment.
Introducing Distributed Ledger Technology into Healthcare Insurance Automation: The Role of Tokenized Wallets
This paper introduces a scalable and GDPR-compliant blockchain architecture that automates healthcare insurance claims through the use of tokenized wallets and NFT-based smart contracts. By enabling real-time eligibility verification and secure integration with EHR systems, the proposed framework significantly reduces claim processing time while enhancing privacy and fraud prevention. The validated prototype demonstrates the practical feasibility of efficient, secure, and automated insurance claim management.
A Distributed Ledger Architecture for Cross-Jurisdictional Healthcare Professional Authentication and Tracking in Universal EHR Systems
This article proposes a blockchain-based architecture for a universal Electronic Health Record (EHR) system that enables secure, transparent, and consent-driven health data sharing across borders. By integrating decentralised digital identity and trusted healthcare professional authentication aligned with European frameworks like EBSI, eIDAS, and EUDI, the solution aims to overcome cross-jurisdictional access challenges. Together, these capabilities could form a key foundation for realising the European Health Data Space (EHDS) vision.
