Face2Face · Face verification

Make sure the passport belongs to the person showing it.

The neural network compares a selfie with the document photo across 512 biometric landmarks. Someone else's passport won't pass. A genuine customer passes on the first try.

Three reasons to match a face to the document

A stranger's passport is useless

A fraudster cannot pass verification with someone else's or a forged ID: the selfie will not match the document photo. Liveness prevents a photo from standing in for a live person.

One person — one account

Face Search (1:N) finds duplicate registrations across your database — even if the customer changed their passport or details.

Genuine customers aren't rejected

The system doesn't confuse different people — and doesn't reject a real customer by mistake. The similarity threshold is configurable for your scenario.

One person — one account, even with a new passport

Face Search looks for one face among many in your database. On every registration it checks the customer against the whole base, so a repeated attempt is rejected even when the passport or details changed.

Stop multi-accounts and welcome-bonus farming.
Catches repeat registrations of previously blocked customers.
Database search takes ~1.5–2 seconds.
Accuracy

Doesn't confuse different people and doesn't reject your own

The model returns a similarity percentage and you compare it with a threshold configured in the dashboard. A genuine customer clears it while someone else's face stays well below it.

Tune the similarity threshold to your use case — from gentle onboarding to strict KYC. The Face2Face dashboard demo starts at 85%, but you decide how strict matching is.
Resilient to change

Recognizes the customer, even when they've changed

A passport photo may have been taken years ago — people change. The algorithm focuses on biometric traits resilient to age, hairstyle, weight and image quality. And the reverse — it does not confuse similar-looking people where simpler systems fail.

On-Premise deployment

Face biometrics never leave your loop

Work in our cloud or deploy the Face Match core into a closed perimeter on your own servers (On-Premise) — selfies, document photos and biometric templates stay with you.

The result: biometric data does not leave the company perimeter — covering regulatory and security requirements.
