Why Liveness Checks Are Essential

There have always been active checks to ensure that documentation is authentic, but the complex methods used in creating false documents can mean they're difficult to tell apart from the real thing. This is where liveness checks come in.

What Is a Liveness Check?

A liveness check is a biometric verification process that confirms a real person is present during identity verification. It detects whether the face being presented is from a live person or a fake representation such as a photo, video, or mask. Understanding identity checking is crucial in this context.

Why They Matter

Liveness checks are essential because they prevent presentation attacks where fraudsters use photos or videos, confirm the document holder is genuinely present, add an extra layer of security to document verification, and reduce fraud in remote onboarding. For more on this topic, see our post on the risks of not doing thorough background checking.

Types of Liveness Checks

Active liveness requires user interaction like blinking or turning their head. Passive liveness works without user action, analysing the image for signs of life. Both methods help prevent spoofing attacks.

Conclusion

Liveness checks are an essential component of modern identity verification. They help ensure that the person presenting documents is genuinely present and not attempting fraud.
