27、em 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 co
28、llaborate 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 t
29、o 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 IS
30、O/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 identifie
31、d during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on t

36、s are expected to support multiple biometric devices and multiple biometric data formats. The Common Biometric Exchange Formats Framework (CBEFF) promotes interoperability of biometric-based application programs and systems developed by different vendors by facilitating biometric data interchange.IS
37、O/IEC 19785-1:2006 defines the following items that enable standardized biometric data interchange:a) a 3-part standardized structure for biometric information records (BIRs) consisting of:1) standardized biometric headers (SBHs);2) biometric data blocks (BDBs, which can be standardized or proprieta
38、ry);3) optional security blocks (SBs);b) variations of the 3-part structure to support BIRs containing:1) only one SBH, one BDB, and possibly one SB (simple BIRs);2) more than one BDB along with the SBHs necessary to encode the BIRs structure and some number of SBs (complex BIRs);c) more than 20 dat
39、a elements and their associated abstract values that can be used in an SBH to describe attributes of a BDB within a BIR, as well as attributes of the BIR itself;d) the concept of a CBEFF patron format (but ISO/IEC 19785-1:2006 does not itself define any patron formats), which is a detailed specifica
40、tion of the structure and content of a particular, standardized BIR;e) the concept of a CBEFF patron, which is a recognized standards organization that has registered with the Biometric Registration Authority and declared its intention to define CBEFF patron format specifications;f) the concept of t
41、he Biometric Registration Authority (RA), which is the mechanism by which unique identifiers are assigned to organizations (standards organizations, vendors, and others) that create BDB formats and CBEFF patron formats (ISO/IEC 19785-2:2006 defines the responsibilities and operations of the Biometri
42、c RA);g) CBEFF data elements see c) above that support, within the SBH, the unique identifiers assigned by the Biometric RA for biometric organizations, BDB formats, biometric products, capture devices, feature extraction algorithms, comparison algorithms, quality algorithms, compression algorithms,
43、 patron formats, and SB formats.Patron formats can be specified in other standards documents and registered in the CBEFF Registration Authority (see ISO/IEC 19785-2:2006), for example, there is a registered patron format specified in ISO/IEC 9834-1:2006. For a complete list of registered patron form
44、ats, consult the CBEFF Registration Authority web site.This part of ISO/IEC 19785 specifies a number of CBEFF patron formats that are considered to be of general utility in a variety of domains of use. Additional SC 37 patron format specifications can be published as new clauses in future amendments
45、 to this part of ISO/IEC 19785, or in other SC 37 International Standards.The CBEFF patron format type unambiguously identifies the CBEFF patron format within the scope of the CBEFF patron format owner. The CBEFF patron format type is unambiguous within the scope of an ASN.1 Object Identifier (see I
46、SO/IEC 9834-1) that identifies the Biometric Registration Authority (see viii ISO/IEC 2015 All rights reservedBS ISO/IEC 19785-3:2015ISO/IEC 19785-3:2015(E)ISO/IEC 19785-2:2006). That ASN.1 Object Identifier (OID) is itself globally unambiguous within the scope of all ASN.1 Object Identifiers, which
47、 forms a widely-used global name-space.NOTE ASN.1 Object Identifiers are used by ITU-T, ITU-R, the UPU, many ISO, and IEC Standards, to identify some IETF MIME types, and for many other purposes. (These acronyms have not been spelled out, as the precise identification of these organizations is not r
48、elevant to this International Standard.)The combination of the Biometric Registration Authority OID, the CBEFF patron format owner, and the CBEFF patron format type forms a larger ASN.1 OID that provides an unambiguous identification of the CBEFF patron format. This part of ISO/IEC 19785 specifies,
49、for each CBEFF patron format that it defines, the ASN.1 OID that unambiguously identifies that CBEFF patron format.
