This part of ISO/IEC 19785 defines structures and data ele ments for biometric information records (BIRs). 1.2 This part of ISO/IEC 19785 defines the concept of a domain of use to establish the applicability of a standard or specification that complies with CBEFF requirements. 1.3 This part of ISO/IEC 19785 defines the concept of a CBEFF patron format, which is a published BIR format specification that complies with CBEFF requirements, specified by a CBEFF patron. 1.4 This part of ISO/IEC 19785 defines the abstract values (and associated semantics) of a set of CBEFF data elements to be used in the definition of CBEFF patron formats. 1.5 This part of ISO/IEC 19785 specifies the use of CBEFF data elements by a CBEFF patron to define the content and encoding of a standard biometric header (SBH) to be included in a biometric information record (i.e. the definition of a CBEFF patron format). 1.6 This part of ISO/IEC 19785 provides the means for identification of the formats of the biometric data blocks (BDBs) in a BIR, but the standardization and interoperability of BDB formats is not in the scope of this part of ISO/IEC 19785. It also provides a means (the security block) for BIRs to carry information about the encryption of a BDB in the BIR and about integrity mechanisms applied to the BIR as a whole, but the structure and content of security blocks is the responsibility of CBEFF patrons and is not in the scope of this part of ISO/IEC 19785. Further, the specification of encryption mechanisms for BDBs and of integrity mechanisms for BIRs is not in the scope of this part of ISO/IEC 19785. 1.7 This part of ISO/IEC 19785 specifies transformations from one CBEFF patron format to a different CBEFF patron format. 1.8 The encoding of the abstract values of CBEFF data elements to be used in the specification of CBEFF patron formats is not in the scope of this part of ISO/IEC 19785. 1.9 ISO/IEC 19785-2 specifies the operation of the Biometric Registration Authority for the issuing of biometric organization identifiers and the registration of BDB formats, CBEFF patron formats, security block formats, and biometric products. 1.10 A future part of ISO/IEC 19785 (ISO/IEC 19785-3) will specify several patron format specifications for which ISO/IEC JTC 1 SC 37 is the CBEFF patron. 1.11 Protection of the privacy of individuals from inappropriate dissemination and use of biometric data is not in the scope of this part of ISO/IEC 19785, but may be subject to national regulation.
