One open hand. One clear answer.
Palm Liveness is a hand check for your verification flows. A few seconds of hand movement tell a live person from automation, without asking who that person is. And it learns with every use.
Open hand · Follow the dots · Pinch · A new challenge for every attempt

The question
Software can now click, type and scroll, just like a person.
So when someone signs up, how do you know a person is really there? Palm Liveness answers that one question, with a few seconds of hand movement.

The hand check
Hold up an open hand, follow a few dots across the screen, then touch thumb and index finger together. It takes a few seconds, in the browser, with the device's camera.
- 1
Hold up an open hand
The camera finds one open hand.
- 2
Follow the dots
Move the hand to each dot on the screen, in order.
- 3
Touch thumb and index finger
A short pinch completes the check.
Every challenge is new, and valid only once.
The dots are placed anew for every attempt. A challenge expires after a short time and can be used once; the next attempt gets a new one.

It doesn't ask who you are.
No name, no document, no face match. Palm Liveness answers a question about the session, not about the person: is a live person here, right now?
- It does not identify anyone
- It does not compare faces
- Where identity matters, combine it with document reading, liveness and face match
What the hand check asks
one question- Name not asked
- Identity document not asked
- Face match not asked
- Is a live person here, right now? asked

Palm Liveness learns, with every use.
It is more than a single check of a single attempt. When the model is confident, it decides. When it is not, it doesn't guess: a person reviews the case, their decision is added to the training data, and the model is retrained on the motion.
The loop below shows the mechanism, not data: which cases a person reviews and how their decisions flow back into the model.

Every uncertain case makes the next decision sharper.
And as automation changes, the check keeps learning with it.

In your verification flow
Add it to any verification flow of the Identivero verification platform: on its own, or alongside document and selfie checks. Under your brand.
- On its own, where you need to know that a live person is there
- Alongside document reading, liveness and face match
- In the web flow under your own brand, like every other step
