CSA Group Information technology — Common Biometric Exchange Formats Framework — Part 1: Data element specification (Adopted ISO/IEC 19785-1:2015, second edition, 2015-08-01)

Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).  For brevity, this Standard will be referred to as "CAN/CSA-ISO/IEC 19785-1" throughout.  At the time of publication, ISO/IEC 19785-1:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.    Scope This part of ISO/IEC 19785 defines structures and data elements for biometric information records (BIRs).  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.  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.  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.  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).  This part of ISO/IEC 19785 provides the means for identification of the formats of the BDBs in a BIR but the standardization and interoperability of BDB formats are 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; the structure and content of security blocks are 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.  This part of ISO/IEC 19785 specifies transformations from one CBEFF patron format to a different CBEFF patron format.  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.  ISO/IEC 19785-3 specifies several patron format specifications for which ISO/IEC JTC 1 SC 37 is the CBEFF patron.  ISO/IEC 19785-4 specifies several security block format specifications for which ISO/IEC JTC 1 SC 37 is the CBEFF patron.  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.
