Biometric modalities can be used to improve security, safety and comfort in different applications. For example it is possible to restrict access to computer systems or buildings by biometric authentication. Since the usage of biometric modalities is considered more and more also for vehicles, in this paper we review two existing approaches of fusing speech, face and additional biometric modalities in automotive applications. We also combine them to an extended concept for an improvement of the achievable comfort and security. Especially we include additional soft biometric modalities to compensate failures of the biometric sensors to ensure business continuity through enhanced availability. However, enhancements of the comfort of biometric authentication systems on one side, often lead to a decrease of their security on the other. In a first theoretical simulation we show the overall comfort improvement, compare the new concept with the selected two existing approaches and discuss potential security implications.
