Biometric identifiers

Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. Biometric identifiers are often categorized as physiological versus behavioral characteristics.


 * Physiological characteristics are related to the shape of the body. Examples include, but are not limited to fingerprint, face recognition, DNA, Palm print, hand geometry, iris recognition, retina and odour/scent.

While biometric identifiers are not commonly used on a stand alone basis in Union Space, they form a part of the information stored on a civilian Union Citizen's CITI, as well as the MITI of a Service Member in the United Stars Military.
 * Behavioral characteristics are related to the behavior of a person, including but not limited to: typing rhythm, gait, and voice. Some researchers have coined the term behaviometrics to describe the latter class of biometrics.
