24、rmats Framework, is an aug-mented and revised version of the CBEFF, the Common Biometric Exchange FileFormat, published in 2005 as ANSI INCITS 398-2005, which was originally publishedas NISTIR 6529-A. This version, ANSI INCITS 398-2008, was developed by the TaskGroup M1.2 on Technical Interfaces of

25、INCITS Technical Committee M1, Biometrics.Please note that the current version of this standard is not backwards compatiblewith earlier versions. Normative annexes have been added for existing patron for-mats.Although the patron formats documented in Annexes E and F were originally devel-oped under

26、the 2005 version of INCITS 398, they also conform to the 2007 revision;references in these annexes are to clauses in the 2005 version of INCITS 398.Summary of Changes from the original CBEFF specification (NISTIR 6529) In addition to the name change, which reflects more accurately the scope of thesp

27、ecification, this revised version incorporates the following new features:A CBEFF Nested Structure. This structure consists of a Root Header fol-lowed by optional Subheaders, one or more CBEFF Basic Structures, and an option-al Security Block (SB). A CBEFF nested structure can include: (a) standard

28、or non-standard biometric data; (b) challenge data; and (c) payload. A nested structure hasbeen specified in order to support multiple biometric data types (e.g., finger, face andvoice) and/or multiple biometric data blocks of the same biometric type (e.g., fingerbiometric data blocks from more than

29、 one finger) within a CBEFF data structure.Nesting CBEFF structures accommodate such requirements and avoid having to uti-lize multiple consecutive CBEFF records for one specific operation. A Subheader/Basic Structure Count. The CBEFF nested structure has re-quired defining this new field. This opti

30、onal field specifies the number of nested lev-els below the current level in a CBEFF nested structure. This field has a value of zeroin the lowest level of a nested structure.The following additional and redefined fields:oA Standard Biometric Header (SBH) Patron Format Identifier optional fieldthat

31、is used in nested struc-tures to identify the CBEFF patron format of thenext lower level in the structure.oA Biometric Feature optional field to further define the type of biometric databeing placed in a CBEFF record. oA Validity Period optional field to denote the period (not before - not after)whe

32、n the biometric data block is valid.o A modified definition of the Creator field. In this specification, the Creator(optional field) specifies the organizational entity (e.g., issuer or application) re-sponsible for the generation of the biometric data. o Addition of a Product Identifier (PID) field

33、. This field identifies the entity (e.g.,Biometric Service Provider (BSP) or transformation application) that created thebiometric data object. This entity may or may not be the same as the entity thatdefined the format of the created data within the biometric data block.ivoAn Index field. This opti

34、onal field contains a unique value associated with aspecific instance of biometric reference (enrollment) data. It may represent adatabase index. Uniqueness pertains only to a specific database. Use andmanagement of this data is the responsibility of the application. oA Challenge-Response field. Thi

35、s optional field specifies the type of informa-tion used to present a challenge to the user or the system.oA Payload field. This optional field shall contain data (e.g., a person-identifi-cation-number) to be attached in a secure way to biometric reference data andused by a service system (e.g., acc

36、ess control system) in case the biometricverification is positive. Reference data is to be specified by the CBEFF patron.Examples include a filename, database item, or URL.Two new Formats have been added: 1. Biometric Information Data Objects for Use within Smart Cards or Other Tokens.This format ha

37、s been defined with the collaboration of technical experts fromISO/IEC JTC 1 SC 17 WG4 and INCITS Technical Committee B10.2. CBEFF Patron Format B, a simple root header for use in domains where morethan one patron format, simple or nested, may be encountered.In addition, more detailed information on

38、 the concept of CBEFF patrons, the currentlist of patrons and how to apply for a new CBEFF patron have been added.Other changes are:Several field names are changed to clarify that they describe attributes of the Bi-ometric Data Block (BDB) rather than the CBEFF-conformant record header:o “Record Dat

39、a Type“ to “Biometric Data Type“.o “Record Purpose“ to “Biometric Purpose“.o “Record Data Quality“ to “Biometric Data Quality“.o “Creation Date“ to “Biometric Creation Date“.Creator/PID field changed to two separate fields (as described above).In Biometric Type table, changed “Palm Geometry“ to “Pal

40、m Print“.In Biometric Type table, added “Foot Print“.Discussion of Object Identifiers (OIDs) has been removed.NIST Biometric Consortium (BC)/Working Group (WG) Patron Format A was re-specified to accommo-date changes to some field definitions and to make it easier touse.Annex C, describing the BioAP

41、I Biometric Identification Record, has beenaligned with changes in 5.2 (Basic Data Structure).The Annex describing the X9.84 Biometric Object (based on the X9.84-2001 ver-sion) was removed. (X9.84-2001 is superseded by X9.84-2003. This version is beingtransposed to ISO through ISO TC68/SC2. Developm

42、ent of the ISO version is under-way.)The Annex describing an example of embedding a CBEFF object has been re-moved. A report including examples of CBEFF utilizations is planned.vviSummary of Changes from the CBEFF 398-2005 specificationUpdated the forward and extended the summary of changes.Removed

43、the Abstract.Changed “Signature Block“ to “Security Block“ throughout the document.Changed “Format Specification“ to “patron format specification.“Updated the introduction to clarify patron usage and refer to existing patron for-mats.Updated the conformance clause.Updated terms and acronyms.Rearrang

44、ed Table 1, and included clarifying notes.Used the BDB Format Owner/Type model for both the Product Owner/Type andthe Device ID Owner/Type.Renumbered the subclauses under 5.2.1 to reflect the sequence in Table 1.Added Device ID.Made the patron formats document structure more consistent.Annex A - Upd

45、ated Patron A table.Annex B - Updated Patron B Table.Changed Biometric Sub Type clause.Added a subclause with a definition of SBH length.Clarified the use of Universal Coordinated Time (UTC) in the date/time specificclauses.Changed CBEFF Header Version.Changed Clause 6 to reflect updated conformance

46、 and registration.Nested CBEFF Structureso The concept of nested structures was improved by clarifying the use of Sub-header/Basic Structure Count in nested structure Sub-headers.o Added informative notes describing the use of records that conform to differ-ent patron formats within a nested structu

47、re for applications that combinerecords from different sources.o The Subheader/Basic Structure Count is now required for nested CBEFFstructures.o Added the definition of a zero level record in a nested structure.Patron Formatso Added text explaining that new patron formats can include additional fie

48、ldsthat are not specified in the standard.o Clarified that the patrons are responsible for maintenance of patron formats.o Patron A Index has been increased to 16 bytes to accommodate GUIDs.o Clarified the usage of a wrapper format (Patron B) for providing self-identifi-cation of contained pa-tron f

49、ormats.viio Assigned Patron Format Identifiers for all patron formats.o Emphasized endian-ness in Patron A.o Clarified byte order for Patron A and B.o Changed Patron D to International Civil Aviation Organization (ICAO) LogicalData Structure (LDS) Patron Format.o Clarified usage of Universal Coordinated Time (UTC) and Binary Coded Dec-imals in Patron Ao Changed Patron A header version.o Added patron formats for PIV and NIST/ITL 2007 Type 99Miscellaneouso Formatted patron format annexes to be similar to each other.o Fixed an incorrect URL in Annex E.BackgroundOn February 21, 1999
