# Liveness check A liveness check is a security feature used to ensure that the person being verified is physically present and alive during the identity verification process. This is typically done to prevent fraud, such as the use of photos, videos, or deepfake technologies to impersonate someone else. The liveness check usually involves prompting the user to perform specific actions, such as blinking, smiling, or turning their head, while their face is being scanned by a camera. The system then analyzes these actions to confirm that the movements are natural and consistent with a live human being, rather than a static image or video playback. By incorporating liveness checks, KYC APIs can enhance the reliability and security of the identity verification process, making it harder for fraudulent actors to manipulate the system. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
