Biometrics are commonly used as a form of which security function?

Explanation:
Biometrics are used to verify identity. They rely on a unique trait—like a fingerprint, facial pattern, iris, or voice—and compare what you present to a stored reference. If it matches, you’re authenticated, meaning you’ve proven who you are and can access the system or resource. Authorization, by contrast, determines what you’re allowed to do after you’re authenticated. Accounting logs what you do for auditing. Encryption protects the data itself, not your identity. In practice, biometric checks are most commonly a form of authentication, often used alongside other factors in multi-factor authentication.
