ActivePassiveLiveness SDK for iOS with SignInKey

The ActivePassiveLiveness SDK for iOS with SignInKey is a powerful tool that allows developers to easily integrate biometric authentication capabilities into their iOS applications. This SDK provides a seamless and secure way for users to authenticate their identity using facial recognition technology.

With the ActivePassiveLiveness SDK, developers can enhance the security of their iOS applications by implementing liveness detection techniques. Liveness detection ensures that the user is physically present and prevents spoofing attempts using photographs or videos. This makes it a reliable solution for applications that require high levels of security.


  • Facial recognition authentication
  • Active liveness detection
  • Passive liveness detection
  • Secure authentication key (SignInKey)
  • Anti-spoofing measures
  • Easy integration

How it Works

The ActivePassiveLiveness SDK utilizes the front-facing camera of the iOS device to capture the user’s facial data for authentication. It incorporates both active and passive liveness detection techniques to ensure the authenticity of the user.

Active liveness detection involves prompting the user to perform specific actions to confirm their presence, such as blinking their eyes or turning their head. This prevents spoofing attempts using static images or recorded videos.

Passive liveness detection analyzes the user’s facial movements during the authentication process to detect signs of liveliness. This helps to further enhance the security and reliability of the authentication process.

The use of a secure authentication key, known as SignInKey, adds an extra layer of security to the authentication process. The SignInKey ensures that only authorized individuals can access the application, reducing the risk of unauthorized access.
