9、icipate 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, government

10、al 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

11、 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 national bodies for voting.

13、nformation technology, Subcommittee SC 37, Biometrics.

16、es within a Common Biometric Exchange Formats Framework (CBEFF) data structure. Each image is accompanied by image-specific metadata contained in a header record. This part of ISO/IEC 29109 establishes tests for checking the correctness of the binary record. The objective of ISO/IEC 19794-6:2005 can

17、not be completely achieved until biometric products can be tested to determine whether they conform to those specifications. Conforming implementations are a necessary prerequisite for achieving interoperability among implementations; therefore there is a need for a standardized conformance testing

18、methodology, test assertions, and test procedures as applicable to specific modalities addressed by each part of ISO/IEC 19794. The test assertions will cover as much as practical of the ISO/IEC 19794-6:2005 requirements (covering the most critical features), so that the conformity results produced

19、by the test suites will reflect the real degree of conformity of the implementations to ISO/IEC 19794-6:2005 data interchange format records. This is the motivation for the development of this conformance testing methodology. This part of ISO/IEC 29109 supports those applications that require use of

20、 iris image data according to ISO/IEC 19794-6:2005. It defines a testing methodology to assure conformance of a vendors application or service to the base ISO/IEC 19794-6:2005 specification. Thus, this part of ISO/IEC 29109 is intended to: establish elements of the conformance testing methodology fr

21、amework that are specific to the iris image-based data record requirements of ISO/IEC 19794-6:2005 conformance testing, define requirements and guidelines for specifying conformance test suites and related test methods for measuring conformity of products and services to the iris image data record r

22、equirements of ISO/IEC 19794-6:2005, and define testing and reporting procedures to be followed before, during, and after conformance testing. This part of ISO/IEC 29109 is applicable to the development and use of conformity test method specifications, conformity test suites for ISO/IEC 19794-6:2005

23、 records, and conformance testing programs for ISO/IEC 19794-6:2005 conformant products. It is intended primarily for use by testing organizations, but may be applied by developers and users of test method specifications and test method implementations.
