Multimodal biometric platform
DCFirst Claim
1. A biometric system, which comprises:
- a biometric client, wherein said biometric client captures biometric images in a plurality of modes;
a router in communication with said biometric client to receive biometric images from said biometric client; and
,a plurality of biometric matching engines in communication with said router to receive biometric images from said router, wherein said plurality of biometric matching engines process biometric images in a plurality of modes, wherein;
said plurality of biometric matching engines comprise;
a first group of biometric matching engines, wherein each biometric matching engine of said first group being configured to process a first set of biometric image types, anda second group of biometric matching engines, wherein each biometric matching engine of said second group being configured to process a second set of biometric image types; and
said router is configurable to operate in a mode where a biometric template is sent to each biometric matching engine of said first group for storing.

Abstract
A multimodal biometric identification or authentication system includes a plurality of biometric clients. Each of the biometric clients may include devices for capturing biometric images of a plurality of types. The system includes a router in communication with the biometric clients. The router receives biometric images from, and returns biometric scores or results to, the biometric clients. The system includes a plurality of biometric matching engines in communication with the router. Each biometric matching engine includes multiple biometric processors. Each biometric processor is adapted to process biometric data of a particular type. The biometric matching engines transmit and receive biometric data to and from the router.
