Confirm a real person is behind every selfie

High-assurance authentication
Add biometric confidence to sign-ups, logins, and transaction approvals without extra hardware.
Cut duplicate accounts
Pair liveness with face matching to catch the same person opening multiple accounts under different identities.
Detect spoofing and deepfakes
Printed photos, screen replays, and synthetic faces get flagged before they reach a human reviewer.
One selfie, a full read on who's really there
Liveness Check does more than pass or fail a photo — it returns a full picture of the face captured.
Passive, single-frame capture
Users take one selfie — no blinking, smiling, or turning their head on command, which keeps onboarding fast.
Spoof and replay detection
Texture, screen-glare, and facial-geometry signals combine to flag printed photos, screen replays, and masks.
Rich face attributes
Age range, gender, emotion, eyewear, facial hair, eye and mouth state, and image quality come back with every check.
Face-match ready
Combine with 1:1 face matching to confirm the live selfie belongs to the same person on a submitted ID.
From selfie to verdict in one request
A single API call takes a base64-encoded selfie and returns a structured liveness and face-attribute result.

What is LumiID Liveness Check?
It's an API that analyzes a single selfie to confirm it was captured from a real, live person rather than a photo, screen replay, mask, or synthetic image.
Is this passive or active liveness detection?
Passive. Users capture one selfie with no blink, smile, or head-turn challenges, which keeps onboarding fast while still detecting spoofing attempts.
What does the API return besides a pass or fail result?
Alongside the liveness result, the response includes face attributes such as age range, gender, emotion, eyewear, facial hair, eye and mouth state, image quality, and the face bounding box.
Can Liveness Check be combined with face matching?
Yes. Liveness Check can be paired with 1:1 face matching to confirm the live selfie belongs to the same person shown on a submitted ID document.
How accurate is the liveness result?
Each selfie is scored with a liveness probability, and a result is classified as live once that score crosses the configured confidence threshold.
