Which term describes identifying individuals by analyzing iris patterns?

• A. Iris Recognition
• B. Gait Recognition
• C. Vein Matching
• D. Sniff Test

Answer: (A)

Biometric identification using iris patterns is called iris recognition. The iris carries highly unique and stable texture details—like ridges, furrows, and crypts—that can be captured with near-infrared imaging and then analyzed by algorithms to confirm or identify a person. This method is known for high accuracy and resistance to change over time, which is why it’s preferred for secure authentication. Gait recognition analyzes how someone walks, captured in video, which can be less reliable in real-world settings. Vein matching looks at vascular patterns beneath the skin (such as palm or finger veins), not the iris. A sniff test is unrelated to biometric identification.
