Executes an isolated HMAC-SHA256 salting loop inside a hardware Secure Execution Environment (TEE) binding factory-fused silicon identifiers (device_uid) with raw biometric vectors without storing templates on-chain.
Derives uncorrelated, purpose-indexed SECP256k1 key pairs across heterogeneous blockchain ledgers (e.g., Bitcoin vs. Ethereum), eliminating cross-chain address linkability and wallet clustering.
Uses a neural network to calculate real-time transaction risk scores (T_risk > 0.30), dynamically triggering CLAHE lighting normalization and FaceNet neural embeddings for spatial Cosine Distance (D_cosine < 0.60) verification.
