Understanding and Using Smile Liveness Detection for Identity Verification

Our Smile Liveness Detection feature helps prevent fraud by ensuring that the person completing identity verification is physically present during the verification process.

How Smile Liveness Detection Works

During the verification process, users will be guided through several steps:

• Positioning their face in the center of the frame

• Adjusting their distance from the camera as prompted

• Maintaining direct eye contact with the camera

• Performing a natural smile when requested

Key Security Features

The system actively monitors for:

• Video injection attempts

• Still image manipulation

• Proper lighting conditions

• Image blur

• Active liveness indicators

Common Rejection Scenarios

The verification may be rejected if:

• The user does not perform a natural smile when prompted

• Pre-recorded images or videos are used

• The user's eyes are not clearly visible

• Lighting conditions are poor

• The face is not properly centered in the frame

Best Practices for Users

To ensure successful verification, users should:

• Complete the verification in a well-lit environment

• Follow all on-screen prompts carefully

• Maintain a natural expression until prompted to smile

• Keep their face centered and at the requested distance from the camera

• Ensure their eyes are clearly visible throughout the process
