A Metaverse User Biometric Authentication Scheme Using Function Encryption

Puntos clave

• The aim is to enhance user authentication and privacy in metaverse environments without storing original biometric data.
• Propose a biometric authentication technique based on function encryption.
• Design a method that decrypts only the results of similarity functions for encrypted biometric feature vectors.
• Incorporate session-based random numbers and pseudonymous identifiers to ensure anonymity.
• Reduce the risk of biometric data leakage during server breaches.
• Present strategies against ciphertext reuse and retransmission attacks.
• Consider computation and communication efficiency while protecting privacy.
