RECOGNITO Product Documentation

  

Features

• Face Recognition: Identify and verify individuals by comparing their facial features.
• Liveness Detection: Determine whether a face is live or spoofed to prevent fraud in authentication processes.
• Pose Estimation: Estimate the pose of a detected face, including Yaw, Roll, Pitch

- Additional Features

• NIST FRVT Top 1 Algorithm: Utilize the top-ranked face recognition algorithm from the NIST FRVT for accurate and reliable results.
• On-premise: Operate entirely within your infrastructure, ensuring data privacy and security.
• Real-time: Perform face recognition, liveness detection, and pose estimation with minimal latency.
• Fully-offline: Function without the need for an internet connection, ensuring reliability and data privacy.

SDK Integration

To use the Recognito SDK in your iOS project, follow these steps:

1. Add facesdk.framework into the project

• Copy and add the SDK framework to your iOS project.
  
  

2. Application License (One-Time License)

• For trial license, share your Bundle ID.

  
                

• Add your license to license.txt file:

  iOS-FaceRecognition-FaceLivenessDetection/license.txt

• Initialize SDK with license.

  iOS-FaceRecognition-FaceLivenessDetection/FaceDemo/ViewController.swift

  Lines 37 to 50 in 6e30f27

  	if let filePath = Bundle.main.path(forResource: "license", ofType: "txt") {
  	do {
  	let license = try String(contentsOfFile: filePath, encoding: .utf8)
  	ret = FaceSDK.setActivation(license)
  	} catch {
  	print("Error reading file: \(error)")
  	}
  	} else {
  	print("File not found")
  	}
  	if(ret == SDK_SUCCESS.rawValue) {
  	ret = FaceSDK.initSDK()
  	}

  Initialization status codes:

  Code	Status
  0	Activate SDK successfully
  -1	License Key Error
  -2	License AppID Error
  -3	License Expired
  -4	Activate Error
  -5	Init SDK Error

3. APIs of SDK

- Activate SDK

+(int)setActivation:(NSString*)license;

Parameters

• Return Value: An integer representing the SDK activation status code.

- Initiate SDK

+(int)initSDK;

Parameters

• Return Value: An integer representing the initialization status code.

- Detect Face

+(NSMutableArray*)faceDetection:(UIImage*)image;

Parameters
