(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.
The term biometrics refers to technologies that measure and analyse human physiological or behavioral characteristics for authentication or identification purposes. Some of the most widely used characteristics or biometric factors are fingerprints, irises, voice patterns and the spatial geometry of the face.
