Which category includes facial recognition, retina scanning, fingerprinting, and hand geometry as verification methods?

• A. Biometrics
• B. Encryption
• C. Cryptography
• D. Decryption

Answer: (A)

Biometrics refers to using unique physical traits to verify identity. Facial recognition, retina scanning, fingerprinting, and hand geometry are all methods that measure a trait and compare it to a stored profile to confirm who you are. This is a form of authentication based on something you are, rather than something you have or know. Encryption, cryptography, and decryption, by contrast, are about protecting and transforming data, not confirming a person’s identity. So biometrics is the category that covers these verification methods.
