Biometric Authentication
Authentication lets an existing Customer prove it is them using their face — no document needed. It is a fast 1:1 check against the identity already enrolled for that Customer.
When to use it
Approving a high-value transaction, unlocking a sensitive action, or re-confirming identity at login (step-up authentication). The Company already knows which Customer is being authenticated and passes that Customer to the session.
How it works
- Face capture & liveness — the Customer takes a selfie; liveness confirms a live person.
- 1:1 match — the selfie is compared against the face stored for that specific Customer.
- Decision — the match score and liveness result combine into an outcome returned to the integrator.
Because the target Customer is known in advance, this is a 1:1 comparison (this face vs that Customer), not a 1:N search across the database.
Outcomes
| Outcome | Meaning |
|---|---|
| Authenticated | The face matched the Customer and liveness passed. |
| Rejected | The face did not match, or liveness/anti-spoofing failed. |
Notes
- No document capture and no OCR — authentication is purely biometric.
- Anti-spoofing (liveness, deepfake, injection detection) applies here exactly as in onboarding.
- To identify an unknown person by face instead of confirming a known one, use Biometric Identification.
