BIOMETRIC

Biometric Technologies
as door locks and card readers which do not have a host processor in the product capable of interacting
directly with a fingerprint sensor, will require a dedicated biometric processor as part of the solution.
Biometric processors are digital ASICs specifically designed for the purpose of biometric authentication.
The processor runs the relevant extraction and matching algorithms and performs enrollment, identification
and verification. As power consumption and size are important in many applications, the biometric
processors must be small and power efficient. The biometric processor is then interfaced to the main
processor of the product over a standard interface, for example a serial port, from which it takes commands
and delivers results.
