React Native offline face enrollment, verification, and liveness detection SDK. Supports iOS and Android. All functions run offline without the need for backend API services.

⚠️ Important: This SDK involves low-level hardware and native algorithms. It must be tested on a physical device; it will not function on an emulator.

Installation

npm install @faceaisdk/react-native-face-sdk

iOS Configuration

Update your ios/Podfile to include the SDK post-install hook:

require_relative '../node_modules/@faceaisdk/react-native-face-sdk/scripts/faceaisdk_post_install.rb'

post_install do |installer|
  react_native_post_install(installer, config[:reactNativePath], :mac_catalyst_enabled => false)
  faceaisdk_post_install(installer)
end

cd ios and run pod install (TensorFlowLiteSwift may take a while depending on the network)
```
cd ios && pod install
```

Add the camera permission to your Info.plist:

<key>NSCameraUsageDescription</key>
<string>We need access to your camera for face recognition and liveness detection.</string>

Android Configuration

Ensure your project's minSdkVersion is at least 24.

Add the camera permission to your AndroidManifest.xml:

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

API Usage

import {
  addFaceBySDKCamera,
  faceVerify,
  livenessVerify,
  getFaceFeature,
  insertFaceFeature,
  addFaceByImage,
  deleteFaceFeature,
} from '@faceaisdk/react-native-face-sdk';

1. Enroll Face by SDK Camera

addFaceBySDKCamera(faceID: string, options?: { mode?: number; showConfirm?: boolean }) => Promise<FaceResult>

2. Face Verification (1:1 + Liveness)

faceVerify(faceID: string, options?: FaceVerifyOptions) => Promise<FaceResult>

3. Liveness Detection

livenessVerify(options?: LivenessVerifyOptions) => Promise<FaceResult>

Data Structures (`FaceResult`)

Property	Type	Description
`code`	`number`	Status code
`message`	`string`	Message
`faceID`	`string`	User identifier
`similarity`	`number`	Similarity score
`liveness`	`number`	Liveness score
`faceFeature`	`string`	1024-bit face feature string
`faceBase64`	`string`	Base64 face image

中文

FaceAISDK 人脸识别、活体检测 React Native 原生插件，支持 iOS 和 Android 双端；所有功能无需后台 API 服务即可离线运行。

⚠️ 重要提示：本 SDK 涉及底层硬件与原生算法，必须使用真机测试，模拟器无法运行。

安装

npm install @faceaisdk/react-native-face-sdk

iOS 配置

在您的 ios/Podfile 中接入必要的脚本：

require_relative '../node_modules/@faceaisdk/react-native-face-sdk/scripts/faceaisdk_post_install.rb'

post_install do |installer|
  react_native_post_install(installer, config[:reactNativePath], :mac_catalyst_enabled => false)
  faceaisdk_post_install(installer)
end

进入 ios 目录并安装 Pod 依赖(TensorFlowLiteSwift 根据网络状态会需要比较长时间)
```
cd ios && pod install
```

在 Info.plist 中添加相机权限描述：

<key>NSCameraUsageDescription</key>
<string>我们需要访问您的相机进行人脸识别与活体检测</string>

Android 配置

确保项目的 minSdkVersion 至少为 24。

在 AndroidManifest.xml 中声明相机权限：

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

核心方法

1. SDK 相机录入人脸

addFaceBySDKCamera(faceID: string, options?: { mode?: number; showConfirm?: boolean }) => Promise<FaceResult>

2. 人脸比对 + 活体检测

faceVerify(faceID: string, options?: FaceVerifyOptions) => Promise<FaceResult>

3. 纯活体检测

livenessVerify(options?: LivenessVerifyOptions) => Promise<FaceResult>

统一返回结构 (`FaceResult`)

属性	类型	说明
`code`	`number`	状态码
`mseeage`	`string`	提示文本
`faceID`	`string`	用户标识
`similarity`	`number`	比对相似度
`liveness`	`number`	活体检测分值
`faceFeature`	`string`	人脸特征值 (1024 位)
`faceBase64`	`string`	人脸图片 Base64 字符串
