Known Faces & Repeat Attempts

Protect your business from repeat fraud and document 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 and emerging sophisticated tactics targeting digital onboarding. Identifying fraud activity across applications can help stop fraud earlier, reduce financial losses, and protect your brand from reputational damage.

Known Faces is fully automated. It works in the background to prevent fraud by detecting repeat offenders and genuine duplicate users at onboarding — without adding friction.

Repeat Attempts - Synthetic Identity Fraud

Stop fraud rings

Protect your business against sophisticated fraud rings and sign-up bonus abuse without compromising on user experience.

Advanced fraud protection

Create multiple layers of protection against biometric spoofs by combining our Selfie or Motion Liveness solutions with Known Faces.

Higher Level of Trust feature image

Build trust at onboarding

Build a higher level of trust with customers at onboarding, by ensuring their biometrics have not been seen previously.

Repeated biometric submissions are a strong sign of fraud and document fraud activity. 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. Because identities and documents can change across applications, repeat fraud is difficult to detect without biometric comparison. Known Faces alerts your business when a facial biometric has been seen by your business before, and flags additional information such as name mismatches to help stop sophisticated fraud earlier.

Modern fraud prevention requires layered defenses. Known Faces strengthens your anti-fraud stack by complementing liveness detection and document verification, helping you detect repeat fraud and document fraud that traditional controls can miss.

Because it operates as a background control within your existing biometric workflows, Known Faces adds protection against sophisticated fraud attempts without introducing friction or changing the onboarding experience for legitimate users.

We’ve saved $10,000 from duplicate users within just three months of using Known Faces. And because Onfido (now part of Entrust) 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. By automating cumbersome in-house processes we’ve saved the team 67 hours and counting in manual fraud reviews.

  • Protecting high-risk or regulated onboarding flows: Add an extra layer of defense where fraud impact is highest.

How does Known Faces work?

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 — helping detect repeat fraud, fraud face activity, and related document fraud attempts.

How long are the biometric captures stored?

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

How long does it take to get the Known Faces results?

No time at all — the results are provided in real-time, to support immediate fraud detection decisions, and are returned through both the Entrust API and Dashboard.

What is document fraud?

Document fraud occurs when an individual alters, manipulates, forges, or reuses identity documents to bypass verification controls. This can include modified IDs, synthetic documents, stolen credentials, or reused identity materials during digital onboarding.

What are document fraud solutions?

Document fraud solutions use advanced technologies such as biometric verification, AI-driven document analysis, and cross-session fraud detection to identify altered, forged, or reused documents. Modern document fraud solutions help organizations reduce onboarding risk while maintaining a smooth user experience.

What types of documents are commonly targeted for fraud?

Commonly targeted documents include government-issued IDs such as passports and driver’s licenses, residence permits, national ID cards, and other official credentials used for identity verification and KYC processes.

How is document fraud detected?

Document fraud detection combines automated document analysis, biometric matching, liveness detection, and behavioral signals to identify inconsistencies, manipulation, or repeated use of the same identity materials. Layered controls strengthen protection against both simple forgery and sophisticated fraud schemes.

Why is document fraud prevention important?

Document fraud prevention helps protect organizations from financial losses, regulatory penalties, reputational damage, and account takeover risk. Even a single successful fraud attempt can undermine onboarding controls and weaken customer trust.

How does document fraud detection fit into identity verification?

Document fraud detection is a core component of identity verification. It works alongside biometric verification and repeat attempt detection to confirm that identity documents are authentic, belong to the applicant, and have not been reused across multiple applications.
