Zero-Knowledge Cryptographic Proofs (ZKP)

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.

ZERO-KNOWLEDGE MATRICES

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

1

Query Initiation

The verifying terminal requests a specific logic fact, e.g., "Prove Age is greater than or equal to 18".

2

Local Generation

The UIID wallet constructs a cryptographic proof mathematically, verifying the claim without reading the birthdate.

3

Instant Validation

The receiving system checks the mathematical envelope, accepting the truth in milliseconds with zero raw data exposure.

REGULATORY MATHEMATICS

GDPR Article 5(1)(c)

Satisfies the European Union's "Data Minimization" principle completely by design.

eIDAS 2.0 Selective

Strictly complies with the upcoming EU requirements for decentralized selective attribute sharing.

FIDO2 Secured

Leverages hardware biometric keys to guarantee that only the authentic owner can issue proofs.

FREQUENTLY ASKED QUESTIONS

Zero-knowledge proofs rely on advanced algebraic systems (bilinear pairings). The government signs the master attribute. The user's device constructs a mathematical proof confirming the attribute satisfies a check (e.g., "age > 18"), which the verifier validates without seeing the age itself.
No. The mathematical circuits are highly optimized inside the UIID native application, generating standard proofs in under 600 milliseconds using minimal mobile hardware resources.
No. Every generated proof envelope uses fresh, random parameters (cryptographic blinding). The verifier receives unique data elements every single time, making tracking mathematically impossible.
