Human Recognition Service (HRS)

  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.
