Biometric verification and biometric authentication both use unique physical characteristics (a biometric) to prove that a person is who they say they are securely online. But each has a different process and different use cases.
Biometric verification is the act of matching a unique biometric characteristic (i.e. a face) against a trusted identity document (such as a driver’s license). This is typically used when an individual is onboarding or enrolling for a service online for the first time.
Biometric authentication validates the unique biometric characteristic (i.e. the face) against the biometric template created during the verification process. This is used when an individual is returning to use an online service after they have onboarded or enrolled.
The best biometric solutions do more than just match biometric data: they must also ensure that the person presenting their biometric is a real person (not a photograph or video used in a presentation attack) and that they’re presenting right now (not a digitally injected attack).
Let’s take two real-world scenarios to further clarify the difference between the two…
Scenario 1: You’re signing up remotely for a new online bank account. To onboard securely, you complete the application and are asked to verify your identity. You scan your driver’s license (or other trusted identity document) using your mobile device. You then scan your face using your device’s user-facing camera. The biometric technology matches your live face against the face on the license. In this scenario, Genuine Presence Assurance is needed to ensure that you are the right person and a real person, verifying in real-time. The process proves that you are who you say you are – your identity is approved and the bank opens your new account. This is an example of biometric verification. Your face biometric is verified against the photo in a trusted identity document to confirm you are who you say you are.
Scenario 2: A week later, you want to check your bank balance online. The bank asks you to authenticate by presenting your face to the camera, which is then matched against the biometric template that you created during the onboarding process. In this scenario, biometric authentication can be delivered using liveness detection, which confirms you are the right person and a real person. If you wanted to transfer $5000 to a friend, the bank can use Genuine Presence Assurance instead of liveness for additional security. This is an example of biometric authentication. You reconfirm your face biometric against the biometric you provided during onboarding to confirm that you have the right to access the account.
Both biometric verification and authentication are integral parts of secure, convenient online security processes. The right biometric solution can help your organization to prevent fraud or other cybercrime without inconveniencing your customers.
iProov’s cloud-based facial biometric technology provides the most secure and convenient way to verify remote users (…and we explain why below!).
Biometric verification should prove three things:
Step 1 ensures that the biometric data matches a real-world, verified identity. This usually happens by verifying the presented biometric against government records, using a trusted identity document such as a passport or driver’s license. Biometric verification is not just about two pieces of data matching each other – it must also match a government-verified identity.
Step 2 ensures that the person presenting their biometric is a real person – many solutions are caught out by attacks that use artifacts, such as masks or photographs.
Step 3 is where iProov’s Genuine Presence Assurance technology is unique. Liveness solutions cannot guarantee that the face being presented during the onboarding or authentication process is actually being presented right now. This leaves them vulnerable to digitally injected attacks, which inject media directly into the data stream and bypass the camera and other device sensors. Digitally injected attacks can use synthetic media such as deepfakes, where a fraudster creates a fake person or takes a photo of a real person and animates it. iProov’s Genuine Presence Assurance supports you across all three steps.
The onboarding of an online user is critically dependent on that person being the right person, a real person, completing the process right now – fraudsters using stolen or fake identities can do a lot of damage if they are not spotted at the onboarding stage.

Once you have all three, you can safely and securely identify users during onboarding. Biometric often verification forms a part of organizations’ regulatory processes, such as Know Your Customer (KYC) and Anti-Money Laundering (AML) compliance. These regulations set out that organizations must be able to prove that they’ve verified the identity and assessed the risks of those they’re doing business with.
Biometric verification eliminates the need for lengthy manual processes during onboarding, such as scanning and signing documents. There’s no need to travel and verify your identity in person. Biometric verification allows your users to verify their identity no matter where they are, and enables them to do it in an effortless way.
Without the security that biometric verification provides during onboarding, you leave the door open for scammers and fraudsters to abuse your online services. One 2021 report found that 1 in 7 new account creations are fraudulent, and another found identity theft in the US rose by 72% between 2018-2019.
Biometric authentication reconfirms that a person is who they claim to be every time they log in or make a transaction. This ensures that the person attempting access ( the ‘visitor’) and the person who created the account (the ‘owner’) are the same person, by matching biometric data.
iProov offers Flexible Authentication to enable organizations to apply the right level of security to each authentication, using either Liveness Assurance or Genuine Presence Assurance. If an individual wants to access their bank account to check a balance, for example, Liveness Assurance offers effortless convenience with the appropriate level of security. If the user wants to transfer $5000, then Genuine Presence Assurance delivers the additional reassurance that the request is not part of a digitally injected attack.
There are scenarios in which you can have authentication without verification: for example, Apple’s FaceID does not require you to verify your identity to set up the authentication which locks your device. But most applications require verification before authentication.
Biometric authentication is crucial because verifying a person’s identity once is not enough. You must also regularly ensure the account has not been compromised. Authentication enables you to continuously ensure that the person onboarded with your organization is the same person attempting to log in each time.
It’s like creating a password for your bank account: you enter it again every time you log in or make a large transaction. The difference is that biometric solutions, such as face verification, achieve this with greater ease for the user and stronger security.
