The authentication method based on physiological measurement is called what?

• A. Biometrics
• B. Behavioral Biometric Technology
• C. Eye Recognition
• D. Hash

Answer: (A)

Biometrics is the method of authentication that uses a person’s physical traits to verify identity. It relies on unique physiological characteristics—such as fingerprints, iris patterns, or facial features—to confirm who someone is. This is different from behavioral biometric technology, which uses how someone acts (like keystroke dynamics or gait). Eye recognition is a specific biometric technique focusing on the eye, but the general term for the concept described is biometrics. A hash, on the other hand, is a cryptographic value used for data integrity and does not identify a person. So the term for authentication based on physiological measurement is biometrics.
