A classification of biometric signatures

The domain of biometrics lacks of a systematical approach for classifying biometric signatures for biometric authentication, detection, and reaction systems. This paper presents a first approach to fill this gap. Outlining the general authentication process and analyzing the meaning of the term signature from selected sciences, a definition of the term biometric signature as (bin|n-)ary coded representation of biometric characteristics is derived. To show the suitability of the suggested definition, its role within the core processes of biometric authentication systems (enrollment, authentication, derollment) is described.
