CBEFF
CBEFF (Common Biometric Exchange Formats Framework) was developed from 1999 to 2000 by the CBEFF Development Team ( NIST) and the BioAPI Consortium. This standard provides the ability for different biometric devices and applications to exchange biometric information between system components efficiently. In order to support biometric technologies in a common way the CBEFF structure describes a set of necessary data elements.
The CBEFF Basic Structure consists of a single SBH (Standard Biometric Header) followed by a BSMB (Biometric Specific Memory Block) and an optional SB (Signature Block).
The CBEFF Nested Structure consists of a Root Header, optional Sub-Headers, CBEFF Basic Structure(s), and an optional SB (Signature Block).
