The Unified Identification Protocol (UIP) is an innovation which empowers patients and legal guardians to generate their unique digital identity for cross-border healthcare. This digital identity seamlessly links to local identifiers across different territories and organizations, bridging the gap between disparate systems. Combined with the International Patient Summary (IPS) – endorsed by the G7 and the EU – UIP is pioneering a new paradigm in telehealth services. Championing a user-centric approach in line with Web 3.0 principles, UIP places data control directly in the hands of patients and their legal guardians. This ensures accurate identification, streamlined access to health data, and robust privacy protection. When harmonized with tools like the SMART-On-FHIR API, FHIR Contract, DID Documents, and blockchain certification, UIP lays down transparent, user-approved guidelines for sharing healthcare data across borders. This framework guarantees that data is securely exchanged, encrypted specifically for the intended recipients upon user consent, adhering to international standards, and in full compliance with prevailing regulations. Furthermore, UIP facilitates certification of health courses and competences for patients, caregivers, and practitioners, enhancing healthcare understanding and management.
