Hardware-Based Biometric Security

Leveraging secure hardware elements for maximum protection

Fingerprint Authentication

Secure fingerprint authentication using device hardware security features like TEE/Secure Enclave.

Face Recognition

Advanced facial recognition secured by hardware-level protection and matching.

Device Binding

Cryptographically binding authentication keys to specific hardware devices.

Zero-Credential Architecture

QuantumPass implements a true zero-credential architecture where service providers never see user credentials. Biometric data never leaves the secure hardware environment of the user's device.

Implementation Details

How QuantumPass integrates with device biometrics

1

Device Registration & Hardware Binding

QuantumPass uses secure hardware elements like Trusted Execution Environment (TEE) or Secure Enclave to generate device-bound cryptographic keys that can only be accessed following successful biometric authentication.

// Using react-native-biometrics for hardware integration
import ReactNativeBiometrics from 'react-native-biometrics'

const rnBiometrics = new ReactNativeBiometrics()

// Generate key pair in secure hardware
rnBiometrics.createKeys('Confirm fingerprint')
  .then((resultObject) => {
    const { publicKey } = resultObject
    // Send public key to server for registration
    sendPublicKeyToServer(publicKey)
  })
2

Hardware Attestation & Verification

During registration, QuantumPass validates the security capabilities of the device and verifies its integrity through hardware attestation.

Biometric Authentication

When a user needs to authenticate, QuantumPass prompts for biometric verification without requiring username entry. The system uses QR codes for service provider identification.

// Authenticate using biometrics
rnBiometrics.createSignature({
  promptMessage: 'Sign in to Service',
  payload: challengeFromServer
})
.then((resultObject) => {
  const { success, signature } = resultObject
  if (success) {
    // Send signature to server for verification
    sendSignatureToServer(signature)
  }
})

Service Provider Integration

Service providers receive cryptographically signed tokens that verify the user's identity without revealing credentials or requiring password database storage.

Key Security Features

Enhanced security through hardware integration

Simulation & Real Hardware Modes

QuantumPass supports both simulation mode (for demos) and real hardware mode by toggling the simulationMode flag in Config.js. This flexibility allows for demonstrations without compromising security in production environments.

Enhanced Implemented with react-native-biometrics

QR Code Integration

Seamless integration with QR code scanning using react-native-camera enables a username-less authentication flow, enhancing both security and user experience.

Enhanced Implemented with react-native-camera

Permission Handling

Proper permission handling for camera access and biometric sensors ensures a smooth user experience while maintaining compliance with platform security requirements.

Cross-Device Synchronization

Securely register multiple devices with cryptographically signed authorizations from existing registered devices.
