This repository demonstrates both face liveness detection and face recognition technology for Flutter on Android and iOS platforms.

In this repository, we integrated KBY-AI's face liveness detection and face recognition technology into the Flutter project for both Android and iOS.

To get Face SDK(server), please visit products here.

You can visit our YouTube video here to see how well our demo app works.

The face recognition project relies on our SDK, which requires a license for each application ID.

• The code below shows how to use the license: https://github.com/kby-ai/FaceRecognition-Flutter/blob/0ed0fea9f86d73d08aff81e25da479c62f2ebc05/lib/main.dart#L68-L94

Make sure you have Flutter installed.
We have tested the project with Flutter version 3.10.2.
If you don't have Flutter installed, please follow the instructions provided in the official Flutter documentation here.

Run the following commands:

flutter pub upgrade
flutter run

If you plan to run the iOS app, please refer to the following link for detailed instructions.

Android

• Copy the SDK (folder libfacesdk) to the folder android in your project.
  
• Add SDK to the project in settings.gradle.

include ':libfacesdk'

• Copy the folder facesdk_plugin to the root folder of your project.
  
• Add the dependency in your pubspec.yaml file.

  facesdk_plugin:
    path: ./facesdk_plugin

• Import the facesdk_plugin package.

  import 'package:facesdk_plugin/facesdk_plugin.dart';
  import 'package:facesdk_plugin/facedetection_interface.dart';

• Activate the FacesdkPlugin by calling the setActivation method:

  final _facesdkPlugin = FacesdkPlugin();
  ...
  await _facesdkPlugin
          .setActivation(
              "Os8QQO1k4+7MpzJ00bVHLv3UENK8YEB04ohoJsU29wwW1u4fBzrpF6MYoqxpxXw9m5LGd0fKsuiK"
              "fETuwulmSR/gzdSndn8M/XrEMXnOtUs1W+XmB1SfKlNUkjUApax82KztTASiMsRyJ635xj8C6oE1"
              "gzCe9fN0CT1ysqCQuD3fA66HPZ/Dhpae2GdKIZtZVOK8mXzuWvhnNOPb1lRLg4K1IL95djy0PKTh"
              "BNPKNpI6nfDMnzcbpw0612xwHO3YKKvR7B9iqRbalL0jLblDsmnOqV7u1glLvAfSCL7F5G1grwxL"
              "Yo1VrNPVGDWA/Qj6Z2tPC0ENQaB4u/vXAS0ipg==")
          .then((value) => facepluginState = value ?? -1);  

• Initialize the FacesdkPlugin:

await _facesdkPlugin
          .init()
          .then((value) => facepluginState = value ?? -1)

• Set parameters using the setParam method:

await _facesdkPlugin
        .setParam({'check_liveness_level': livenessLevel ?? 0})

• Extract faces using the extractFaces method:

final faces = await _facesdkPlugin.extractFaces(image.path)

• Calculate the similarity between faces using the similarityCalculation method:

double similarity = await _facesdkPlugin.similarityCalculation(
              face['templates'], person.templates) ??
          -1;

To build the native camera screen and process face detection, please refer to the lib/facedetectionview.dart file in the repository.

This file contains the necessary code for implementing the camera screen and performing face detection.
