Which recognition method uses walking patterns to identify people?

• A. Iris Recognition
• B. Gait Recognition
• C. Sniff Test
• D. Butt Biometrics

Answer: (B)

Gait-based recognition is the idea that you can identify someone by the way they walk. It analyzes motion characteristics such as stride length, cadence, leg swing, arm movement, and torso sway. These patterns tend to be distinctive enough to differentiate individuals, and they can be captured from a distance with video, often without the person’s cooperation. This makes gait recognition useful in surveillance or scenarios where contacting the person isn’t feasible. It’s different from iris recognition, which relies on unique patterns in the eye, and from the other options, which aren’t real methods for identifying people by walking. Keep in mind that gait can be influenced by clothing, objects being carried, footwear, and surface, but the core idea remains assessing walking patterns to identify an individual.
