FAQ

1. What is the CAF Face Liveness SDK and what is its main functionality?

Answer:

The CAF Face Liveness SDK provides a solution for verifying whether the face captured by a mobile device's camera is from a live person and not a photo, video, or other forms of spoofing. It’s widely used in scenarios where identity verification is crucial, such as KYC (Know Your Customer), fraud prevention, and secure access.

2. What are the system requirements for the CAF Face Liveness SDK on iOS?

Answer:

The SDK supports iOS 13.0 and above, ensuring compatibility with modern iOS devices. Your iOS project should meet the minimum target of iOS 13.0.

For more requirement details, such as Xcode and Swift versions, please refer to the Requirements section.

3. What permissions are required to use the SDK?

Answer:

The SDK requires the following permissions:

  • Camera access (NSCameraUsageDescription in Info.plist)

  • Internet access (NSAppTransportSecurity for network requests, if necessary)

Ensure these permissions are properly declared in your app's Info.plist file and handle permission requests appropriately.

4. How do I integrate the CAF Face Liveness SDK into my iOS project?

Answer:

To integrate the SDK:

  1. Add the SDK framework to your Xcode project.

  2. Configure necessary permissions for the camera and internet access in your app’s Info.plist.

  3. Initialize the SDK in your application's lifecycle, typically within viewDidLoad() of your main view controller.

For detailed instructions, please refer to the Builder setup section

5. What is the current version of the SDK, and where can I find version-specific details?

Answer:

The current version of the SDK is regularly updated. You can find the latest version information, including changelogs and version-specific details, here.

6. How do I start the Face Liveness verification process in my app?

Answer:

To start the liveness check, follow these steps:

  1. Build the liveness session using the SDK’s builder.

  2. Start the liveness verification by calling the startSDK() method.

  3. Capture the result in the delegate methods.

For more details on how to initiate the process, refer to the Start SDK section.

7. What are the typical errors or issues that could occur, and how can I troubleshoot them?

Answer:

Some common errors include:

  • Camera permission not granted: Ensure your app requests the necessary permissions at runtime.

  • SDK initialization failure: Check your SDK setup and ensure it is properly initialized in the app lifecycle.

  • Network errors: Ensure the device has an active internet connection for the liveness check to succeed.
