Which of the following terms is used to describe using unique information to verify an individual's identity?

The term that best describes using unique information to verify an individual's identity is authentication. Authentication refers to the process of confirming the identity of a user based on specific criteria, which can include knowledge factors like passwords, possession factors like security tokens, or inherent factors linked to an individual, such as biometrics.

Biometric verification, while closely related, specifically refers to the use of physical characteristics—like fingerprints, facial recognition, or retina scans—to establish a person's identity. It is a subset of the broader concept of authentication. Therefore, while biometric verification is indeed a form of authentication, the more general term that encompasses all methods of verifying identity—including biometrics—is authentication itself.

Identity confirmation and profile analysis do not directly relate to the processes involved in uniquely verifying identity in the same encompassing manner that authentication does. Identity confirmation may imply confirming someone's claimed identity without the unique verification mechanisms, whereas profile analysis focuses on assessing data associated with an individual's behavior rather than verifying identity uniquely.
