What the Face Match API does

Document checks prove a document is real. Face Match proves the right person is holding it. The API compares two facial images and returns a similarity score, with a decision against the threshold you configure, so onboarding can stop impersonation without a human reviewer.

Pair it with Liveness Detection to be sure the selfie is a live capture and not a photo of a photo.

Consent is part of the contract

Facial images are biometric data. Capture the person's consent before the check; Profiden stores the consent record and purges images after processing.

Benefits of the Face Match API

Compare a selfie to the photo on an ID document or KYC record.

Stops impersonation

The person must match the ID, not just hold it.

Tunable threshold

Set strictness per journey: stricter for lending, lighter for gig sign-up.

Real-time

Decision in the same request.

Nothing retained

Images are purged after the comparison.
