This layer manages the digital identity objects of practitioners, facilities, institutions, students, patients, insurers, and embassies. Every entity receives a structured identity, verification state, and audit-ready trust footprint.

• SHA-256 cryptographic identity hashing
• Structured professional identity objects per entity
• Verification state tracking across all lifecycle events
• Audit-ready trust footprint with full history

This is where the public and institutions interact with the system. Live search, QR scans, verification pages, status cards, badge rendering, and public trust interfaces all sit here.

• Live public search by name, license, specialty, state
• QR code verification — any camera, any phone
• USSD *556# for zero-internet verification
• Verified status badge rendering and embedding

Every major trust event can be anchored to Nigeria's blockchain channel within the One Health Global network. This creates immutable proof of issuance, update, approval, status change, and verification history.

• Hyperledger Fabric 2.5 private ledger for council operations
• Ethereum mainnet public anchors for external proof
• Immutable audit trail — no deletion possible
• Cross-border blockchain recognition infrastructure

AI supports anomaly detection, fraud scoring, suspicious application review, workforce intelligence, claims pattern recognition, and dashboard insights. It does not replace regulators — it strengthens decision support.

• 94.7% fraud detection accuracy as of Q1 2026
• Diploma mill database: 2,847 institutions flagged globally
• Document forensics: metadata + OCR + visual AI analysis
• 47 active fraud signal types in real-time monitoring

This layer supports renewal logic, CME monitoring, facility compliance, payroll truth, staffing integrity, and other real operational workflows tied to healthcare governance.

• Automated renewal deadline notifications and enforcement
• CME credit tracking and council reporting
• IPPIS payroll cross-reference — monthly automated cycle
• Salary block trigger on expired or suspended license

This is the international mobility layer. It routes requests, assembles credential packages, connects registries, supports embassies, and enables cross-border trust corridors.

• NHS UK Band 5–8 automatic qualification mapping
• DHA UAE direct eSCRP application integration
• SCFHS Saudi Arabia credential translation
• AU Continental 54-state recognition framework

Digital trust also extends to physical reality through QR badges, downloadable certificates, institutional plaques, digital badges, and NFC-linked identity tools.

• NFC RFID terminals across 840+ government facilities
• Dynamic QR codes refreshed every 24 hours
• Downloadable and printable verification certificates
• NFC smart card integration for physical ID
