Identity Solutions on the TACEO Network
TACEO's identity solutions power privacy-preserving identity systems at global scale. The solutions are in production and trusted by partners including World and zkPassport, providing the backbone for anonymous, sybil-resistant identity verification.
Our customers 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 that need threshold-secured nullifiers
- Anonymous voting and private credential systems
- Wallet recovery without custodial key exposure
Threshold Passport Identification
Match passport attributes across parties without revealing the underlying document data.
Best fit:
- Identity solutions based on physical id documents (passports, ID cards)
- Issue an unique and unlinkable identifier
- Resistant against document issuing authority
Confidential Biometrics
Run biometric matching and verification in MPC - no plaintext biometric data leaves the user's device or passes through a single party.
Best fit:
- Identity systems based on biometric data (palm, iris, finger, etc.)
- Enforce uniqueness among user base
- Reduce liabilities by handling encrypted data only
