Authentication Concepts Associated with Gait Analysis

C.

The correct answer is C. Something you do.

Gait analysis is a type of behavioral biometric authentication method that analyzes a person's walking pattern or mannerisms. It involves measuring various physical parameters such as the length of a person's stride, the angle of their foot, and the movement of their hips and shoulders.

Behavioral biometrics is a form of authentication that relies on a person's unique behavior patterns, such as typing speed, mouse movements, and voice patterns, to verify their identity. Gait analysis falls under this category since it is based on a person's unique walking pattern.

The other authentication concepts listed in the question are:

A. Somewhere you are: This is a type of authentication that verifies the user's location. For example, a system might require a user to be physically present in a particular location, such as a secure building or office.

B. Something you are: This is a type of authentication that verifies a person's physical characteristics, such as their fingerprint, iris pattern, or facial features. This type of authentication is known as biometric authentication.

D. Something you know: This is a type of authentication that verifies a user's knowledge of a particular piece of information, such as a password or PIN.

In summary, gait analysis is a type of behavioral biometric authentication that verifies a person's identity based on their unique walking pattern, making it most closely associated with the authentication concept of "Something you do."
