Towards a General Definition of Biometric SystemsMarkus SchattenauthorMiroslav BacaauthorMirko CubriloauthorA foundation for closing the gap between biometrics in the narrower and the broader perspective is presented trough a conceptualization of biometric systems in both perspectives. A clear distinction between verification, identification and classification systems is made as well as shown that there are additional classes of biometric systems. In the end a Unified Modeling Language model is developed showing the connections between the two perspectives.Dynamical Systems2009-08International Journal of Computer Science Issues, IJCSI Journal (Paginated)
