A short selfie.
A simple experience.
Capture a short video in your browser. Soliton checks for human presence through physical signals.
THE PRESENCE CHECKILLUSTRATIVE
Human foundation for
trust in the AI era.
Soliton proves human presence through physics, laying the foundation for trusted interactions and human control.
THE SOLITON FOUNDATION
A new standard for trust
The internet needs a reliable way to know when a real person is present. We reimagined human verification through physics, helping businesses distinguish human participation from automation and connect it to the actions that matter.

PRIVACY AT THE FOUNDATION
Prove presence.
Keep the video private.
With a private deployment, the video stays on the device. Only the measured reflection is sent for analysis, and a human-or-not result comes back.

Choose how
you verify.
Physics-based liveness at the core, with document verification and face matching to support your identity flow.
LIVENESS
Standard security liveness
No sound or light emitted. Approximately two seconds of capture, with our lightest payload and fastest processing.
LIVENESS
Medium security liveness
Relies on sound reflection. Approximately two seconds of capture.
LIVENESS
High security liveness
Relies on sound and light reflection. Approximately six seconds of capture.
IDENTITY
Document verification
Bring identity document checks into your verification flow.
1:N MATCHING
One face. Many records.
Match a face against your enrolled identities to find potential matches.
Approximate capture times. Setup and analysis take additional time.

HOW IT WORKS
Real presence.
Measured through reflections.
High-security liveness combines light and sound. The engine analyzes physical reflections to distinguish human presence from synthetic media.

The screen projects light.
The camera measures its reflection.
Acoustic reflection
The speaker emits inaudible ultrasound.
The microphone records the echo.
USE CASES
From human presence
to trusted action
Keep people in control of sensitive actions. Connect proof of presence to explicit approval and a clear record of who approved what.
THE FLOW
Proof
Establish real human presence.
Authorize
Connect intent to an action.
Attest
Record who approved what.

FOR DEVELOPERS
Easy to integrate.
Built for your website.
Add human verification with the Soliton Web SDK. Open the capture flow in your app, let Soliton handle the selfie, and check the result securely from your server.

npm install @soliton-id/web-sdkOpen a verification
JavaScript
import { open } from "@soliton-id/web-sdk";
// Your backend selects liveness_tier and returns the verification URL.
const { url } = await fetch("/your-api/start-verification", {
method: "POST",
}).then(response => response.json());
open({

onComplete: () => {

// Match liveness_tier, then check verified and partial_verification.
},
onError: ({ code }) => console.error(code),
});Your server selects Standard, Medium, or High liveness and stores the verification ID and tier. The same SDK works in sandbox and production. API keys stay on your server.
