Biometric Verification

Known Faces

Protect your business from repeat fraud with enhanced biometric verification. Known Faces automatically compares faces in selfies and videos against those that have previously passed through your onboarding system, and flags if the face has been seen before — giving you an extra line of defense against sophisticated repeat fraud.

Detect repeat fraud

Repeated biometric submissions are a strong sign of fraud. Professional fraud rings and criminal organizations repeatedly attempt to infiltrate systems by reusing fraudulent biometrics, and just one successful attempt can cause lost revenue and reputational damage. Known Faces alerts your business when a facial biometric has been seen by your business before, and flags additional information such as name mismatches.

We’ve saved $10,000 from duplicate users within just three months of using Onfido’s Known Faces. And because Onfido provides a simple output without creating any more work for the customer, it’s now easier for our in-house teams to do their job at scale.

Known Faces works with our Selfie and Motion biometric verification solutions, providing an additional layer of security to flag if a biometric capture has previously been onboarded by your business.

Facial biometric information is stored according to either your data deletion policy with Onfido, or maximum database retention period applying specifically to our Known Faces solution, taking into account applicable biometric laws.

No time at all — the results are provided in real-time, and are returned through both the Onfido API and Dashboard.
