A high-level optimum design methodology for multimodal biometric systems

Biometric systems are designed by expert developers who look - with trial-and-error approaches - for reasonable solutions by considering the available hardware architecture, some - possibly conflicting - quality goals, and the application constrains. Typically drawbacks of these approaches are waste of time and results far from the optimum. We propose a new design methodology for multimodal biometric systems that applies high-level system design techniques to better structure the design procedure. The proposed methodology avoids the drawbacks of the common design practice and allows to create a flexible general-purpose and effective design environment for multimodal biometric systems.
