PROVE THE TRUTH
WITHOUT REVEALING
THE DATA.
Verify critical attributes—such as age ranges, nationalities, or financial solvency—without exposing physical documents or database elements. Secure local selective disclosure mathematically.
OVERDISCLOSURE IS
A MAJOR THREAT.
To prove simple facts like "over 18" or "holds a valid passport", legacy systems force you to scan your entire document. This exposes your full name, date of birth, home address, and unique document serial number to unvetted third-party services.
Once captured, these unencrypted copies are distributed across servers, creating a golden database target for identity theft. This overdisclosure pattern compromises privacy and violates basic GDPR compliance models.
Severe Data Leak Liability
Storing full passport records for simple age gate checks introduces massive data protection fines.
Corporate Overreach
Consumers are forced to choose between sharing their intimate private data or being locked out of modern services.
SELECTIVE DISCLOSURE
WITHOUT EXPOSURE.
UIID leverages state-of-the-art cryptographic proofs (ZKP). You present a mathematical guarantee that a specific statement is true, while the underlying raw data remains securely locked in your device's hardware enclave.
Attribute-Level Credentials
Isolate parameters and prove individual facts (like 'Citizenship = EU') without disclosing anything else.
Local Proof Construction
All heavy mathematical proof computations occur on-device in under one second, ensuring total client-side isolation.
MATHEMATICAL CERTAINTY
- ✓ Mathematical signature binding (BBS+ & Groth16)
- ✓ Unlinkable proofs prevent tracking
- ✓ Dynamic challenge-response patterns
- ✓ Complete verification in under 5ms
CRYPTOGRAPHIC INTEGRITY CHANNELS
Groth16 Snarks
Generate lightweight, ultra-secure zk-SNARK mathematical proofs locally on your mobile device.
Unlinkable Proofs
Prevent correlation. Presenting the same proof twice generates two unique cryptographic envelopes.
Secure Elements
Asymmetric keys reside strictly inside Apple Secure Enclave or Android Keystore ecosystems.
Anti-Quantum
Engineered using post-quantum secure cryptographic algorithms to protect future assets.
ZKP VERIFICATION LOOP
Query Initiation
The verifying terminal requests a specific logic fact, e.g., "Prove Age is greater than or equal to 18".
Local Generation
The UIID wallet constructs a cryptographic proof mathematically, verifying the claim without reading the birthdate.
Instant Validation
The receiving system checks the mathematical envelope, accepting the truth in milliseconds with zero raw data exposure.
