National bodies that are members of ISO or
10、 IEC 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, g
11、overnmental 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
12、, 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 national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the nati
13、onal 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 for identifying any or all such patent rights. ISO/IEC 29109-2 was prepared by Joint Technical Committee ISO/IEC
14、 JTC 1, Information technology, Subcommittee SC 37, Biometrics. ISO/IEC 29109 consists of the following parts, under the general title Information technology Conformance testing methodology for biometric data interchange formats defined in ISO/IEC 19794: Part 1: Generalized conformance testing metho
15、dology Part 2: Finger minutiae data Part 4: Finger image data Part 5: Face image data Part 6: Iris image data Part 8: Finger pattern skeletal data Part 9: Vascular image data Part 10: Hand geometry silhouette data The following parts are under preparation: Part 3: Finger pattern spectral data Part 7

17、 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 correctness of the binary record. The requirem
18、ents 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; there is therefore a need for a standard
19、ized 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 critical features), so that the conform
20、ity 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 29109 supports those applications that
21、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 Conformance Testing Met hodology framew
22、ork 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 services to the Finger Minutiae-based
23、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, conformity test suites for ISO/IEC 197
24、94-2:2005 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.

26、ns and test procedures, as applicable to the biometric data interchange format standard relating to finger minutiae data (i.e. ISO/IEC 19794-2). It establishes tests of assertions of the structure of the finger minutiae data format as specified in ISO/IEC 19794-2:2005 (Type A Level 1 as defined in I
27、SO/IEC 29109-1:2009), tests of assertions of internal consistency by ch ecking the types of values that may be contained within each field (Type A Level 2 as defined in ISO/IEC 29109-1:2009), and tests of semantic assertions (Type A Level 3 as defined in ISO/IEC 29109-1:2009).

Specifically, they
30、shall use the test methodology specified in ISO/IEC 29109-1:2009, Clauses 6, 7 and 8, and all Level 1 and Level 2 tests shall use the assertions defined in Table 2. Implementations of ISO/IEC 19794-2:2005 tested according to the methodology specified shall be able to claim conformance only to those
31、Biometric Data Record (BDR) requirements specified in ISO/IEC 19794-2:2005 that are tested by the test methods established by this methodology.
