This specification describes the XFS service class for Biometrics Device (BIO). The specification of this service class includes definitions of the service-specific commands. Biometrics refers to metrics related to human characteristics and biology. Biometrics authentication can be used as a form of identification and/or access control. This is an overview of biometrics, as well as an introduction to the terminology used in this document. It introduces to XFS the concept of scanning a person’s biometric data in raw image form (raw biometric data), then processing it into a smaller more concise form that is easier to manage (biometric template data). The first scan of a user is called ENROLLMENT as the user is effectively being enrolled into a scheme by recording their biometric data. Thereafter subsequent scans of the user can be compared to the original data in order to verify who they say they are (VERIFICATION), or alternatively used to identify them as a specific individual (IDENTIFICATION).
