Which term involves authentication based on Biometric data?

• A. Biometric security
• B. Password-based authentication
• C. Multi-factor authentication
• D. Smart Card

Answer: (A)

Biometric data authentication relies on unique physical or behavioral traits, such as fingerprints, iris patterns, or facial features, to verify identity. The term that describes using this form of authentication is biometric security, which focuses on confirming who you are by comparing biometric samples to stored templates. This approach is different from password-based authentication, which depends on something you know, and from smart cards, which depend on something you have. It’s also a form of authentication that can be part of multi-factor setups, combining with other factors for stronger security. While biometrics offer convenient and strong user linkage, they require careful handling of privacy and template protection, and they’re commonly used as one piece of a broader security strategy rather than a standalone solution.
