31、ederation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that co
32、mmittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accor
33、dance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requir
34、es approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

37、rom IHS-,-,-viiIntroduction Biometric-based authentication systems and applications 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 sy
38、stems developed by different vendors by facilitating biometric data interchange. ISO/IEC 19785-1 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 heade
39、rs (SBHs), 2) biometric data blocks (BDBs, which may be standardized or proprietary), and 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 necessar
40、y to encode the BIRs structure and some number of SBs (complex BIRs); c) more than 20 data 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/
41、IEC 19785-1 does not itself define any patron formats), which is a detailed specification 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 d
42、eclared its intention to define CBEFF patron format specifications; f) the concept of the 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 for
43、mats (ISO/IEC 19785-2 defines the responsibilities and operations of the Biometric 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, patron formats and SB formats.
44、 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 may be published as new clauses in future amendments to this part of ISO/IEC 19785, or in other SC 37 Inte
45、rnational Standards. The CBEFF patron format identifier unambiguously identifies the CBEFF patron format within the scope of the CBEFF patron identifier. The CBEFF patron format identifier is unambiguous within the scope of an ASN.1 Object Identifier (see ISO/IEC 9834-1) that identifies the Biometri
46、c Registration Authority (see ISO/IEC 19785-2).That ASN.1 Object Identifier (OID) is itself globally unambiguous within the scope of all ASN.1 Object Identifiers, which forms a widely-used global name-space.

47、tandards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-viii 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 purpose
48、s. (These acronyms have not been spelled out, as the precise identification of these organizations is not relevant to this International Standard.) The combination of the Biometric Registration Authority OID, the CBEFF patron identifier, and the CBEFF patron format identifier forms a larger ASN.1 OI
49、D that provides an unambiguous identification of the CBEFF patron format. This part of ISO/IEC 19785 specifies, for each CBEFF patron format that it defines, the ASN.1 OID that unambiguously identifies that CBEFF patron format.
