Identification through Fingerprints uses what?

• A. Unique patterns used for personal identification.
• B. Passwords and usernames alone.
• C. Visual resemblance of faces.
• D. Behavioral cues like gait only.

Answer: (A)

Fingerprint identification relies on the unique patterns of ridges on each fingertip. No two people have the exact same arrangement of this ridge pattern and its detailed minutiae, and these features stay consistent over a person’s life. Because of that, fingerprint data can be captured and compared to stored records to verify identity with high accuracy. That’s why the correct choice describes unique patterns used for personal identification.

Other options mix in different kinds of credentials or biometrics: passwords and usernames are digital credentials, facial resemblance refers to facial recognition, and gait is a behavioral biometrics. None of these describe how fingerprints identify someone.
