Information technology — Common Biometric Exchange Formats Framework — Part 1: Data element specification

ISO/IEC 19785-1:2015 defines structures and data elements for biometric information records (BIRs). ISO/IEC 19785-1:2015 defines the concept of a domain of use to establish the applicability of a standard or specification that complies with CBEFF requirements. ISO/IEC 19785-1:2015 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. ISO/IEC 19785-1:2015 defines the abstract values (and associated semantics) of a set of CBEFF data elements to be used in the definition of CBEFF patron formats. ISO/IEC 19785-1:2015 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). ISO/IEC 19785-1:2015 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. ISO/IEC 19785-1:2015 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.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document wil
