(The term biometrics is derived from the Greek words bio meaning life and metric meaning to measure.) There are two main types of biometric identifiers: Physiological characteristics: The shape or composition of the body. Behavioral characteristics: The behavior of a person. Examples of physiological characteristics used for biometric authentication include fingerprints; DNA; face, hand, retina or ear features; and odor.
