Zero Knowledge Face Proofs

Zero Knowledge Face Proofs represent a revolutionary approach to biometric verification that combines facial recognition technology with zero-knowledge cryptography. This technology allows you to create encrypted proofs of facial identity that can be verified without revealing the underlying biometric data.

What are Zero Knowledge Face Proofs?​

Zero Knowledge Face Proofs are cryptographic tokens that prove facial identity without exposing the actual facial data. They enable:

  • Privacy-Preserving Verification: Verify identity without storing or transmitting raw biometric data
  • Decentralized Storage: Proofs are stored on IPFS (InterPlanetary File System) for decentralized access
  • Tamper-Proof: Cryptographic integrity ensures proofs cannot be forged or modified
  • Selective Disclosure: Choose what information to reveal during verification

Key Features​

🔒 Privacy First

Your facial data never leaves your control. Only encrypted proofs are created and stored.

🌐 Decentralized

Proofs are stored on IPFS, ensuring no single point of failure or control.

🔐 Cryptographically Secure

Advanced zero-knowledge proofs ensure mathematical certainty of identity verification.

📱 Multi-Platform

Works across desktop, mobile (iOS/Android) platforms with consistent security.

⚡ Real-Time Verification

Instant verification with configurable liveness detection and difficulty levels.

How It Works​

1. Encryption Phase​

  • Capture facial image(s) with optional liveness detection
  • Generate cryptographic proof of facial identity
  • Store encrypted proof on IPFS
  • Return proof token for future verification

2. Verification Phase​

  • Present proof token with new facial image
  • System verifies identity without accessing original biometric data
  • Returns verification result with optional metadata

3. Preview Phase​

  • Examine proof contents without full verification
  • View public data and configuration settings
  • No biometric verification required

Use Cases​

Digital Identity​

  • Secure login systems
  • Identity verification for services
  • KYC (Know Your Customer) compliance

Access Control​

  • Physical and digital access management
  • Event attendance verification
  • Secure document access

Financial Services​

  • Banking authentication
  • Payment verification
  • Fraud prevention

Healthcare​

  • Patient identity verification
  • Medical record access
  • Prescription verification

Security Benefits​

  • No Biometric Storage: Original facial data is never stored
  • Zero-Knowledge Verification: Proves identity without revealing data
  • Tamper Detection: Any modification to proofs is immediately detectable
  • Forward Secrecy: Compromised proofs don't affect future verifications
  • Audit Trail: Complete verification history without privacy compromise

Getting Started​

To begin using Zero Knowledge Face Proofs:

  1. Create a Proof: Use the /encrypt endpoint to generate your first proof
  2. Verify Identity: Use the /decrypt endpoint to verify against stored proofs
  3. Preview Contents: Use the /preview endpoint to examine proof metadata
  4. QR Code Integration: Use /encrypt-qr-code for QR-based proof generation

Technical Requirements​

  • Authentication: Valid API token required
  • Image Format: Base64 encoded images
  • Platform Support: Desktop, iOS, Android
  • Liveness Detection: Optional but recommended for security
  • Password Protection: Optional additional security layer
