Biometric security typically relies on identifying individuals through what?

• A. To identify individuals through unique physical characteristics.
• B. To encrypt communications.
• C. To compress video.
• D. To route network traffic.

Answer: (A)

Biometric security relies on identifying individuals through unique physical characteristics. Things like fingerprints, iris patterns, facial features, or voice are distinctive to each person, so a system can compare a live sample to a stored template to confirm who you are or whether you should be granted access. This approach leverages traits that are intrinsic to the person and not easily shared or remembered like passwords. The other options describe different tasks: encrypting communications protects data in transit, compressing video reduces file size, and routing network traffic directs data through a network. None of these involve identifying a person based on their inherent traits, which is why they’re not about biometric security.
