Which method is used to verify a person's identity with biometrics?

The method used to verify a person's identity with biometrics is verification. Verification involves confirming that a person is who they claim to be, typically by comparing a biometric sample (like a fingerprint or facial recognition) against a stored template that represents their identity.

In the context of biometric systems, when an individual presents a biometric trait, the system checks it against a reference stored in a database to establish whether the biometrics match, thereby verifying the individual’s identity. This is distinct from other concepts like identification, which generally seeks to determine who someone is, often by providing a set of candidates for matching rather than confirming a single identity. Authentication and validation, while related, encompass broader processes; authentication may involve both verifying identity and granting access based on that identity, and validation generally refers to ensuring that a system or process meets certain criteria or standards. Thus, verification is specifically focused on confirming identity through biometric means.
