Identity networks address rare book authentication by issuing digital certificates linked to physical copies via NFC/RFID tags. Blockchain records provenance, ownership history, and condition reports. Verifiable credentials (VCs) for libraries/collectors prove legitimacy without exposing sensitive data. AI compares digital scans with certified templates, while decentralized identifiers (DIDs) ensure tamper-proof records. Interoperable standards enable global verification across institutions.
