Identity Solutions on the TACEO Network
TACEO's identity solutions power privacy-preserving identity systems at global scale. TACEO:OPRF is in production and trusted by partners including World and zkPassport, providing the backbone for anonymous, sybil-resistant identity verification.
These solutions let developers build identity systems that verify without surveilling: nullifiers that can't be correlated, passport attributes that can be matched without exposure, and biometric checks that leave no plaintext trail.
Solutions
Distributed Nullifiers
Privacy-preserving deterministic nullifiers computed by a threshold of independent MPC nodes. No single party can evaluate or link nullifiers on its own.
Best fit:
- ZK identity systems (like World ID) that need threshold-secured nullifiers
- Anonymous voting and private credential systems
- Wallet recovery without custodial key exposure
Private Passport Matching
Match passport attributes across parties without revealing the underlying document data. Built on the same MPC network TACEO co-architected for zkPassport.
Confidential Biometrics
Run biometric matching and verification in MPC - no plaintext biometric data leaves the user's device or passes through a single party.
