What the Liveness Detection API does

Remote onboarding is only as strong as its weakest capture. Liveness Detection analyses the selfie for signs of a real, present person, without asking them to perform awkward gestures, and returns a decision your flow can act on before running Face Match.

It works passively on a single frame or actively with a short guided capture when your risk policy calls for it.

Consent is part of the contract

Facial images are biometric data. Capture consent before the check; images are purged after processing.

Benefits of the Liveness Detection API

Prove the selfie is a live person, not a photo, screen or mask.

Blocks spoofing

Printed photos, screens and masks are rejected.

Low friction

Passive mode needs no gestures from the user.

Real-time

Runs before Face Match in the same flow.

Policy-driven

Choose passive or active capture per journey.

Liveness Detection API: frequently asked questions
