MULTIMODAL BIOMETRIC SYSTEMS OVERVIEW
Eugen Lupu, Petre G. Pop · 2008
Abstract: Biometric systems allow automatic person recognition based on physical or behavioral features which belong to a certain person. Each biometric feature has its limits and no biometric system is perfect so unimodal biometric systems raise a variety of problems. To over fulfilling some of the mentioned inconvenient and limitations and to increase the level of security the multimodal biometric systems are used. This paper discusses the main features of the multimodal biometric system: architecture, level of fusion, methodology used for integrating the multiple verifiers and normalization techniques. The main applications of the multimodal biometric systems are also presented.
