11、ization) and IEC (the International Electrotechnical Commission) 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

12、 to deal with particular fields of technical activity. 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

13、 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. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted

14、by the joint technical committee are circulated to national 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 pat

ISO/IEC 29109-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 37, Biometrics. ISO/IEC 29109 consists of the following parts, under the general title

19、g and transmitting one or more finger minutiae records, possibly within a Common Biometric Exchange Formats Framework (CBEFF) data structure. Each minutia may be accompanied by subject-specific metadata contained in a header record. This part of ISO/IEC 29109 defines tests for checking the correctne

20、ss of the binary record. The requirements of ISO/IEC 19794-2 cannot be completely achieved until biometric products can be tested to determine whether they conform to its specifications. Conforming implementations are a necessary prerequisite for achieving interoperability among implementations; the

21、re is therefore a need for a standardized conformance testing 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 is practical of the ISO/IEC 19794 requirements (covering the most cr

22、itical features), so that the conformity results produced by the test suites will reflect the real degree of conformity of the implementations to ISO/IEC 19794 Data Interchange Format records. This is the motivation for the development of this conformance testing methodology. This part of ISO/IEC 29

23、109 supports those applications that require use of finger minutiae data according to ISO/IEC 19794-2:2005. It defines a testing methodology to assure conformance of a vendors application or service to the base ISO/IEC 19794-2:2005 specification. Thus, it is intended to: establish elements of the Co

24、nformance Testing Met hodology framework that are specific to the Finger Minutiae-based Data Record requirements of ISO/IEC 19794-2:2005 conformance testing, define requirements and guidelines for specifying confor mance test suites and related test methods for measuring conformity of products and s

25、ervices to the Finger Minutiae-based Data Record requirements of ISO/IEC 19794-2:2005, and define test 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, c

26、onformity test suites for ISO/IEC 19794-2:2005 records, and conformance testing programs for ISO/IEC 19794-2:2005 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.
