National bodies that are members of ISO or IEC

27、 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, gover

28、nmental 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 desc

29、ribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted.

This second edition can

33、cels and replaces the first edition (ISO/IEC 19785-1:2006), which has been technically revised.

34、ations Part 4: Security block format specifications This is the second ISO/IEC standard on CBEFF. Previous versions were published by the National Institute of Standards and Technology (an agency of the government of the United States of America) and the Biometric Consortium Working Group. Since the

35、 last official non-ISO/IEC release was designated Version 1.1, the first version of this ISO/IEC 19785-1 International Standard was designated Version 2.0, and this version is designated Version 3.0. This is to distinguish the versions of CBEFF products in the marketplace. Version 3.0 is fully backw

36、ard compatible with Version 2.0.vi ISO/IEC 2015 All rights reservedBS ISO/IEC 19785-1:2015ISO/IEC 19785-1:2015(E) Introduction The Common Biometric Exchange Formats Framework (CBEFF) promotes interoperability of biometric- based applications and systems by specifying standard structures for biometri

37、c information records (BIRs) and a set of abstract data elements and values that can be used to create the header part of a CBEFF-compliant BIR. A biometric information record (BIR) is an encoding in accordance with a CBEFF patron format (see below). It is a unit of biometric data for storage in a d

38、atabase or for interchange between systems or parts of systems. A BIR always has at least two parts: a) a standard biometric header (SBH); b) at least one biometric data block (BDB). It may also have a third part called the security block (SB). CBEFF places no requirements on the content and encodin

39、g of a BDB except that its length is to be an integral number of octets; the several parts of ISO/IEC 19794 specify standardized BDB formats for a number of biometric types. The primary purpose of CBEFF is to define abstract data elements (data elements with a set of defined abstract values, with th

40、eir semantics) that are expected to be of general utility as parts of the SBH in biometric information records. This part of ISO/IEC 19785 defines these data elements. A CBEFF patron format is defined for a particular domain of use. A CBEFF patron format is a full bit- level specification of encodin

41、gs that can carry some or all of the abstract values of the CBEFF data elements defined in this part of ISO/IEC 19785 (possibly with additional abstract values determined by the CBEFF patron), together with one or more biometric data blocks (BDBs) containing biometric data. It is intended that there

42、 be a limited number of CBEFF patron formats in any given domain of use. However, new technologies may evolve that need new encoding rules (or support of more or different CBEFF data elements) and hence may require new CBEFF patron formats for a given domain of use. CBEFF also has a requirement that

43、 a Biometric Registration Authority exists to assign unique identifiers to biometric organizations, to biometric data block (BDB) formats, to security block (SB) formats, and to CBEFF patron format specifications (see below), to publish them where appropriate, and to ensure that no conflicts occur b

44、etween identifiers. CBEFF introduces the concept of assigning a unique identifier to a biometric organization. A CBEFF biometric organization is any organization, public or private, that requests and receives a biometric organization identifier from the Biometric Registration Authority. CBEFF also i

45、ntroduces the concept of a CBEFF patron. A CBEFF patron is an organization (registered as a biometric organization) that specifies or intends to specify one or more CBEFF patron formats in an open and public manner. Only public standards organizations such as a standards body, working group, or indu

46、stry consortium can register as CBEFF patrons (other CBEFF biometric organizations are not CBEFF patrons). A CBEFF patron obtains a biometric organization identifier from the Biometric Registration Authority but has privileges beyond those of ordinary CBEFF biometric organizations: it can define, re

47、gister, and publish one or more CBEFF patron formats. The biometric organization identifier of a CBEFF patron can (but need not) be encoded in BIRs conforming to the patron formats defined by that CBEFF patron. CBEFF also defines the concept of a CBEFF biometric data block (BDB) format owner. A CBEF

48、F BDB format owner is an organization (registered as a CBEFF biometric organization) that specifies one or more BDB format specifications. A BDB format owner obtains a CBEFF biometric organization identifier from the Biometric Registration Authority. A BDB format owner can be a public standards orga

49、nization (that would, coincidentally, also qualify as a CBEFF patron) or any organization that has a need to define its own vendor-specific BDB formats, whether they are to be published or not. A CBEFF BDB format owner defines one or more BDB formats and assigns a BDB format identifier that unambiguously identifies that BDB format within those defined by the BDB format owner. A BDB format identifier (and the corresponding format) may, but need not, be registered with the Biometric Registration Auth
