Biometrics measures unique personal attributes or behaviors. What type of biometric analysis is the most accurate?

Fingerprints
Signature Dynamics
Iris Scan
Hand Geometry

Explanation

Answer: C - The iris scan is the most accurate biometric analysis. The iris is the colored portion of the eye that surrounds the pupil. The iris has unique patterns, rifts, colors, rings, coronas, and furrows. The uniqueness of each of the characteristics within the iris is captured by a camera and compared with the information gathered during the enrollment phase. The iris remains constant through adulthood, which reduces the type of errors that can happen during the authentication process.
