Which technology category focuses on physical traits such as fingerprints and retinal scans?

• A. Digital forensics
• B. Physical Biometric Technology
• C. Behavioral Biometric Technology
• D. Network security

Answer: (B)

Physical biometric technology focuses on anatomical features that you can measure from the body, like fingerprints or iris patterns. These traits are inherent and relatively stable, making them reliable for identifying or authenticating a person when you use a fingerprint reader or an iris scanner. Behavioral biometric technology, on the other hand, relies on patterns of behavior—how you type, your voice, or your gait—which can vary with context and effort. Digital forensics deals with analyzing digital evidence from devices, not identifying people by physical traits, and network security is about protecting data and systems rather than biometric identification.
