Description / Abstract:
This International Standard provides a standard interface to
hardware biometric modules designed to be integrated in embedded
systems which can be constrained in memory and computational power.
This International Standard 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 in two
levels:
—For low level implementations, a frame definition is
provided, as well as the coding of all commands and their relevant
responses. Being defined as a single-master/multiple-slave
half-duplex protocol, these messages can be implemented over any
communication interface at the physical and link layers. The
definition of such communication interfaces is outside of the scope
of this International Standard.
—A C-based function header description, for those
manufacturers that want to provide a C-library for integration as a
Software Development Kit for the overall embedded system.
Regarding security, this International Standard defines two
kinds of devices:
—Type A: devices that, due to lack of processing
capabilities, do not implement any kind of security mechanism.
—Type B: devices that implement security mechanisms for
achieving confidentiality, integrity and/or authenticity. Use of
the Type B kind of devices is recommended. For Type B devices a set
of minimum requirements is defined, but the security mechanisms to
be used are out of the scope of this International Standard.
Low level implementation is outside of the scope of the
normative part of this International Standard, although an
informative annex (see Annex B) is provided.
Security mechanisms, although considered in this International
Standard, are outside of the scope of this International Standard,
and are referred to other relevant standards. In particular, key
management is outside of the scope of this International Standard,
and is expected to be done prior to the application of this
International Standard.
Specifications and requirements for Embedded BioAPI
subcomponents, or any kind of devices suitable to implement
Embedded BioAPI, are outside of the scope of this International
Standard.
