22、mmission) form the specialized system 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.

23、ISO and IEC technical committees collaborate 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,

24、ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to nati

25、onal bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national 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. ISO and IEC shall not be held responsible f

26、or identifying any or all such patent rights. ISO/IEC 19785-4 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 37, Biometrics. ISO/IEC 19785 consists of the following parts, under the general title Information technology Common Biometric Exchange Forma

27、ts Framework: Part 1: Data element specification Part 2: Procedures for the operation of the Biometric Registration Authority Part 3: Patron format specifications Part 4: Security block format specifications BS ISO/IEC 19785-4:2010ISO/IEC 19785-4:2010(E) ISO/IEC 2010 All rights reserved vIntroductio

28、n Biometric verification and identification are important techniques for the authentication and/or identification of an individual. Biometric data used in biometric verification and identification has to be from a trusted source with no interference in transmission (integrity). It might or might not

29、 be necessary for it to be kept secret (encryption) depending on security policy. This part of ISO/IEC 19785 provides for both integrity and encryption of the biometric data. To ensure interoperability, the Common Biometric Exchange Formats Framework (CBEFF) was specified in ISO/IEC 19785-1 to assoc

30、iate meta-data with one or more Biometric Data Blocks (BDBs). In ISO/IEC 19785-1, the options for integrity and encryption, and the concept of a security block (SB) to contain security information related to these options are defined, but the format and detailed content of security blocks (SB format

31、s) are not specified. There are several steps in the chain, starting from a CBEFF patron format. First, the patron format can determine that the abstract value of the CBEFF data element CBEFF_BDB_encryption_options is fixed as NO ENCRYPTION and that the CBEFF data element CBEFF_BIR_integrity_options

32、 is fixed as NO INTEGRITY. In this case, there is no need for a security block to be required in that patron format. If the patron format requires the inclusion of a security block in some circumstances, it can fix it as one of the security blocks defined in this part of ISO/IEC 19785 (or as some ot

33、her security block), or can include the CBEFF data elements CBEFF_SB_format_owner and CBEFF_SB_format_type to identify one of these or some other security block format. Besides the security block formats defined in this part of ISO/IEC 19785, there will be many possible CBEFF security block formats

34、meeting different needs. For example, a security block format is specified for the ILO seafarers profile in ISO/IEC 24713-3. The security block format specified in Clause 5 is designed to be as general as possible. The security block format specified in Clause 6 is designed to provide a basic securi

35、ty provision and supports integrity only. This part of ISO/IEC 19785 specifies two security block formats. The first security block specifies a general-purpose security block format with optional elements for encryption, and for integrity, using RFC 3852 Cryptographic Message Syntax (CMS), with cert

36、ain modifications to EnvelopedData, EncryptedData, SignedData, and AuthenticatedData, to meet the needs and requirements in expressing the security of biometric information in conformance with CBEFF. The second is named signature-only security block format, which is also defined using RFC 3852. The

37、general-purpose security block format specified in this part of ISO/IEC 19785 also contains optional Authentication Context for Biometrics (ACBio) instances specified in ISO/IEC 24761. ACBio also uses the RFC 3852 Cryptographic Message Syntax scheme. The inclusion of ACBio instances enables the secu

38、rity levels of the systems producing the authenticated biometric to be determined. The optional use of ACBio instances is an important part of the provision of a telebiometric authentication infrastructure (TAI) 3.

39、2010(E) ISO/IEC 2010 All rights reserved 1Information technology Common Biometric Exchange Formats Framework Part 4: Security block format specifications 1 Scope This part of ISO/IEC 19785 specifies security block formats (see ISO/IEC 19785-1) registered in accordance with ISO/IEC 19785-2 as formats

40、 defined by the CBEFF biometric organization ISO/IEC JTC 1/SC 37, and specifies their registered security block format identifiers. NOTE The security block format identifier is recorded in the standard biometric header (SBH) of a patron format (or defined by that patron format as the only available

41、security block format). The general-purpose security block format provides for specification of whether the biometric data block (BDB) is encrypted or the SBH and BDB have integrity applied (or both), and can include ACBio instances (see ISO/IEC 24761). This security block provides all necessary sec

42、urity parameters, including those used for encryption or integrity. It does not restrict the algorithms and parameters used for encryption or integrity, but provides for the recording of such algorithms and parameter values. It is a matter for profiling to determine, for a particular application are

43、a, what algorithms and parameter ranges can be used by the generator of a security block, and hence what algorithms and parameter ranges have to be supported by the user of a security block. This is out of the scope of this part of ISO/IEC 19785. The second security block is more limited, but simple

44、r (and in particular cannot contain ACBio instances, and does not support encryption of the BDB). 2 Normative references The following referenced documents are indispensable for the application of this document.
