facetec-react-native-adaptor

React Native bridge for FaceTec SDK - Biometric facial verification for iOS and Android.

Features

• Liveness Detection: Anti-spoofing verification to ensure a real person is present
• Photo ID Match: Enrollment with ID document scanning and face matching
• Authentication: 3D-3D face match against previously enrolled users
• Full Platform Support: Works on both iOS and Android
• Configurable: Pass your own FaceTec credentials at runtime

Requirements

General

• React Native >= 0.68.0
• FaceTec SDK license and credentials (obtain from FaceTec Developer Portal)

iOS

• iOS 12.0+
• Xcode 14+
• FaceTec.xcframework (must be added manually)

Android

• minSdkVersion 21
• compileSdkVersion 33+
• FaceTec SDK AAR file (included in the package)

Installation

npm install facetec-react-native-adaptor
# or
yarn add facetec-react-native-adaptor

iOS Setup

1. Add FaceTec.xcframework to your iOS project:

   • Download FaceTec SDK from your FaceTec developer account
   • Drag FaceTec.xcframework into your Xcode project
   • Ensure it's added to "Frameworks, Libraries, and Embedded Content" with "Embed & Sign"

2. Add required permissions to Info.plist:

<key>NSCameraUsageDescription</key>
<string>Camera access is required for facial verification</string>

3. Run pod install:

cd ios && pod install

Android Setup

The FaceTec SDK AAR is already included in the package. Just add required permissions to AndroidManifest.xml:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />

Usage

Basic Example

import { init, liveness, photoMatch, authenticate, parseResponse, FaceTecConfig } from 'facetec-react-native-adaptor';

// Configure with your FaceTec credentials
const config: FaceTecConfig = {
  deviceKeyIdentifier: 'YOUR_DEVICE_KEY_IDENTIFIER',
  appKey: 'YOUR_APP_KEY',
  baseURL: 'https://your-facetec-server.com',
  publicFaceScanEncryptionKey: '-----BEGIN PUBLIC KEY-----\n...\n-----END PUBLIC KEY-----',
  productionMode: false, // Set to true for production
  language: 'es', // 'es' for Spanish, 'en' for English
  primaryColor: '#417FB2', // Color for text and UI elements
  logoURL: 'https://example.com/your-logo.png', // Optional logo URL
};

// Initialize the SDK (call once at app startup)
async function initializeFaceTec() {
  try {
    const success = await init(config);
    console.log('FaceTec initialized:', success);
  } catch (error) {
    console.error('Failed to initialize FaceTec:', error);
  }
}

// Perform liveness check
async function checkLiveness() {
  try {
    const result = await liveness();
    const response = parseResponse(result);

    if (response.wasProcessed) {
      console.log('Liveness verified!');
    }
  } catch (error) {
    console.error('Liveness check failed:', error);
  }
}

// Enroll user with Photo ID
async function enrollUser() {
  try {
    const result = await photoMatch();
    const response = parseResponse(result);

    if (response.wasProcessed) {
      // Save externalDatabaseRefID for future authentication
      const userId = response.externalDatabaseRefID;
      console.log('User enrolled with ID:', userId);
    }
  } catch (error) {
    console.error('Enrollment failed:', error);
  }
}

// Authenticate existing user
async function authenticateUser(userId: string) {
  try {
    const result = await authenticate(userId);
    const response = parseResponse(result);

    if (response.wasProcessed) {
      console.log('User authenticated successfully!');
    }
  } catch (error) {
    console.error('Authentication failed:', error);
  }
}

Using Default Export

import FaceTec, { FaceTecConfig } from 'facetec-react-native-adaptor';

const config: FaceTecConfig = {
  deviceKeyIdentifier: 'YOUR_DEVICE_KEY',
  appKey: 'YOUR_APP_KEY',
  baseURL: 'https://your-server.com',
  publicFaceScanEncryptionKey: '...',
  productionMode: false,
};

// Initialize
await FaceTec.init(config);

// Check liveness
const livenessResult = await FaceTec.liveness();

// Enroll with Photo ID
const enrollResult = await FaceTec.photoMatch();

// Authenticate
const authResult = await FaceTec.authenticate('user-reference-id');

API Reference

init(config: FaceTecConfig): Promise<boolean>

Initialize the FaceTec SDK with your configuration. Must be called before any other methods.

Parameters:

• config.deviceKeyIdentifier: Your FaceTec Device Key Identifier
• config.appKey: Your FaceTec App Key (Production Key)
• config.baseURL: URL of your FaceTec Server SDK backend
• config.publicFaceScanEncryptionKey: Your FaceTec Public Encryption Key
• config.productionMode: (optional) Set to true for production mode, defaults to false
• config.language: (optional) UI language - 'es' for Spanish, 'en' for English, defaults to 'en'
• config.primaryColor: (optional) Hex color for text and UI elements, defaults to '#417FB2'
• config.logoURL: (optional) URL to your logo image to display in the FaceTec UI

Returns: true if initialization was successful.

liveness(): Promise<string>

Perform a liveness check to verify a real person is present.

Returns: JSON string with the verification result.

photoMatch(): Promise<string>

Perform enrollment with Photo ID document scanning and face matching.

Returns: JSON string with enrollment result including externalDatabaseRefID.

authenticate(externalReferenceId: string): Promise<string>

Authenticate a user against a previous enrollment.

Parameters:

• externalReferenceId: The ID returned from a previous photoMatch() call.

Returns: JSON string with authentication result.

parseResponse(responseString: string): FaceTecResponse

Helper function to parse FaceTec response strings.

Returns: Parsed FaceTecResponse object.

Configuration Interface

interface FaceTecConfig {
  deviceKeyIdentifier: string;
  appKey: string;
  baseURL: string;
  publicFaceScanEncryptionKey: string;
  productionMode?: boolean;
  language?: 'es' | 'en';
  primaryColor?: string;
  logoURL?: string;
}

Response Interface

interface FaceTecResponse {
  wasProcessed: boolean;
  success?: boolean;
  scanResultBlob?: string;
  externalDatabaseRefID?: string;
  [key: string]: any;
}

Server Requirements

This SDK requires a FaceTec Server SDK backend to process the biometric data. Your server must implement the following endpoints:

• GET /session-token - Returns a session token
• POST /liveness-3d - Process liveness check
• POST /enrollment-3d - Process enrollment
• POST /match-3d-2d-idscan - Process Photo ID match
• POST /match-3d-3d - Process authentication

Refer to the FaceTec Server SDK documentation for implementation details.

Obtaining FaceTec Credentials

1. Sign up at FaceTec Developer Portal
2. Create a new application
3. Obtain your:
   • Device Key Identifier
   • App Key (Production Key)
   • Public Face Scan Encryption Key
4. Set up your FaceTec Server SDK backend

Troubleshooting

iOS Build Issues

1. FaceTec module not found: Ensure FaceTec.xcframework is properly added to your Xcode project.

2. Bridging header issues: Verify the bridging header path in your project's Build Settings.

Android Build Issues

1. SDK not found: The AAR is included in the package. Make sure your build.gradle is configured correctly.

2. Multidex issues: Enable multidex in your android/app/build.gradle:

android {
    defaultConfig {
        multiDexEnabled true
    }
}

Runtime Issues

1. Initialization fails: Verify your credentials are correct and match your FaceTec account.

2. Network errors: Ensure your baseURL is correct and the server is accessible.

3. "SDK not initialized" errors: Make sure to call init() before using other methods.
