CBEFF
defines a common set of data elements necessary to support multiple
biometric technologies. It accommodates any biometric technology.
It includes the definition of format and content for data elements
such as:
(1)
A
biometric data header that contains such information as version
number, length of data, whether the data is encrypted or not, etc.,
for each biometric type available to the application or system;
(2)
Biometric
data (content not specified);
(3)
Any
other required biometric data or data structures
CBEFF
also describes the means (through a Registration Authority) for obtaining
a unique value for identifying the format (Owner and Type) of the
biometric data.
CBEFF does not attempt to achieve compatibility among different biometric
technologies, but merely identifies them and facilitates their
co-existence in a system or application. Although it is conceivable that
industrial or user groups may agree upon common standard template formats
within the biometric data structures defined in CBEFF, the definition of
the content of these biometric data structures is not addressed.
CBEFF
focuses on the description of the Biometric data elements. It also defines
CBEFF
Patrons. A CBEFF Patron is an organization that has defined a standard or
specification incorporating a biometric data object that meets CBEFF
requirements. Examples of CBEFF Patrons are the BioAPI Consortium and ANSI
Subcommittee X9, Working Group F4.
In
order to decode CBEFF data, the applications need to have previous
knowledge of the Patron and the data encoding scheme that was used. Therefore, a
Patron identifier is not included within the CBEFF definition. Each CBEFF
Patron is required to define which CBEFF Optional Fields are present in
their format and how the data elements are extracted and processed
(details such as the data encoding scheme are left up to the CBEFF
Patrons).
The CBEFF Technical Development Team has proposed that further CBEFF
development be undertaken under the umbrella of the recently formed Biometrics
Interoperability, Performance, and Assurance Working Group sponsored
by NIST and the Biometric Consortium. For more information on future plans, please click
