CDSA/HRS (Common Data Security Architecture/Human
Recognition Service) is a CSSM (Common Security Services Manager)
EMM (Elective Module Manager). It is intended to provide a high-level
generic authentication model, suited to use for any form of human
authentication. Particular emphasis has been made in the design
on its suitability for authentication using biometric technology.
It covers the basic functions of Enrollment, Verification,
and Identification, and includes a database interface to allow a
biometric service provider (BSP) to manage the identification population
for optimum performance.
It also provides primitives which allow the application to
manage the capture of samples on a client, and the Enrollment, Verification,
and Identification on a server.
The HRS is designed for use by both application developers
and biometric technology developers. To make the integration of
the technology as straightforward and simple as possible (thus enhancing
its commercial viability), the approach taken is to hide or encapsulate
to the extent possible the complexities of the biometric technology.
This approach also serves to extend the generality of the interface
to address a larger set of potential biometric technologies and
applications.
