Provides a standard interface to hardware biometric modules designed to be integrated in embedded systems which can be constrained in memory and computational power. It specifies a full interface for such hardware-based biometric modules. This interface, called Embedded BioAPI, is defined by the specification of commands to be implemented by these modules. Such a specification is done on two levels. Low level implementation is not covered. Security mechanisms, although considered, are outside of the scope, and are referred to in other relevant standards. In particular, key management is outside of the scope, and is expected to be done prior to the application of it. Specifications and requirements for Embedded BioAPI subcomponents, or any kind of devices suitable to implement Embedded BioAPI, are also outside of the scope.
