Sub-second
Median liveness decision
Liveness Checks
Real human. Real moment.
Detect spoofs without slowing anyone down. Passive liveness decides from a single frame in under a second. No head turns, no blinking prompts, no friction.

Capabilities
What's in the box.
Production-ready building blocks. Wire them up the way your team needs.
Passive liveness
No head turns, no blinking prompts. We decide from a single frame so the user never feels they're being tested.
Common attack coverage
Designed to flag printed photos, screen replays, and video loops: the attack vectors we see most often in production traffic.
Active challenges, on demand
When risk rises, step the user up to a short active challenge such as a head turn or smile. Same SDK, no extra integration.
Built into the verification flow
Liveness runs alongside age and document checks in a single hosted session. One integration covers all of it.
How it works
Plug it in. Ship in days.
01
Capture
The hosted flow selects the cleanest frame from the camera automatically.
02
Analyse
Multiple signals are combined into a single liveness decision, server-side.
03
Score
A liveness verdict is returned alongside the rest of the verification result.
04
Decide
Pass through to face match, or trigger an active challenge for borderline cases.
Use cases
Built for teams that move.
- Account recovery and password reset
- High-value transaction step-up authentication
- Remote onboarding for regulated products
- Workforce check-in and shift verification
- Age-gated checkouts where a static photo would not be enough
FAQ
Common questions.
Does the user need to move or blink?
No. The default flow is fully passive: one frame, no prompts. Active challenges are available when you want a stronger guarantee for higher-risk events.
What kind of attacks do you cover?
The system is calibrated against the presentation attacks we see most often in production: printed photos, on-screen replays, and short video loops. Coverage of more advanced attacks evolves continuously alongside the threat landscape.
Are you certified by an independent lab?
Independent third-party certification is on the roadmap. Today we publish our methodology and operating points so that you can validate our results against your own challenge set.
