This security technology can involve biometrics.

• A. Passwords
• B. Tokens
• C. Smart Cards
• D. Digital Certificates

Answer: (A)

Biometrics is about confirming identity through who you are, not what you know. A smart card is a device that can carry credentials and, in many systems, requires a biometric check to use those credentials. For example, you might present the card and scan a fingerprint to unlock the private key stored on the card, or the card reader may enforce a biometric match before granting access to the underlying security token. This combination—something you have (the card) plus something you are (the biometric)—is why smart cards can involve biometrics. Passwords are purely knowledge-based, so biometrics isn’t inherent to them. Tokens are separate devices that generate codes, and while some setups can add a biometric step, it’s not a defining feature of tokens. Digital certificates are credentials used in PKI; a biometric check might protect access to the system used with the certificate, but the certificate itself isn’t biometric.
