36、ecifications ISO/IEC 2015 All rights reserved viiBS ISO/IEC 19785-3:2015ISO/IEC 19785-3:2015(E) Introduction Biometric-based authentication systems and applications are expected to support multiple biometric devices and multiple biometric data formats. The Common Biometric Exchange Formats Framework
37、 (CBEFF) promotes interoperability of biometric-based application programs and systems developed by different vendors by facilitating biometric data interchange. ISO/IEC 19785-1:2006 defines the following items that enable standardized biometric data interchange: a) a 3-part standardized structure f
38、or biometric information records (BIRs) consisting of: 1) standardized biometric headers (SBHs); 2) biometric data blocks (BDBs, which can be standardized or proprietary); 3) optional security blocks (SBs); b) variations of the 3-part structure to support BIRs containing: 1) only one SBH, one BDB, a
39、nd 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 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
40、 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 specification of the structure and content of a particular, standardized BIR; e) the concept of a CBEFF patron, which is a recognized st
41、andards organization that has registered with the Biometric Registration Authority and declared 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 (s
42、tandards organizations, vendors, and others) that create BDB formats and CBEFF patron formats (ISO/IEC 19785-2:2006 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
43、for biometric organizations, BDB formats, biometric products, capture devices, feature extraction algorithms, comparison algorithms, quality algorithms, compression algorithms, patron formats, and SB formats. Patron formats can be specified in other standards documents and registered in the CBEFF Re
44、gistration 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 formats, consult the CBEFF Registration Authority web site. This part of ISO/IEC 19785 specifies a number of CBEFF patron forma
45、ts 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 to this part of ISO/IEC 19785, or in other SC 37 International Standards. The CBEFF patron format type unambiguously iden
46、tifies 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 ISO/IEC 9834-1) that identifies the Biometric Registration Authority (see viii ISO/IEC 2015 All rights reservedBS ISO/IEC
47、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 forms a widely-used global name-space. NOTE ASN.1 Object Identifiers are used by ITU-T, ITU-R, the UPU, many ISO, and I
48、EC 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 relevant to this International Standard.) The combination of the Biometric Registration Authority OID, the CBEFF patron
49、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, for each CBEFF patron format that it defines, the ASN.1 OID that unambiguously identifies that CBEFF patron format.
