13、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. ISO and IEC technical committees collabora
14、te 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, ISO/IEC JTC 1. International Standards are
15、 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 national bodies for voting. Publication as an
16、International Standard requires approval by at least 75 % of the national bodies casting a vote.

20、pecifies data interchange formats for recording, storing 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
21、 ISO/IEC 29109 defines tests for checking the correctness 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 fo
22、r achieving interoperability among implementations; there 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
23、of the ISO/IEC 19794 requirements (covering the most critical 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 c
24、onformance testing methodology. This part of ISO/IEC 29109 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
25、. Thus, it is intended to: establish elements of the Conformance Testing Methodology 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 conformance test suites and related te
26、st methods for measuring conformity of products and services 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 developmen
27、t and use of conformity test method specifications, conformity 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 me
28、thod specifications and test method implementations.

29、Part 2: Finger minutiae data 1 Scope This part of ISO/IEC 29109 specifies elements of conformance testing methodology, test assertions 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
30、 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 ISO/IEC 29109-1:2009), tests of assertions of internal consistency by checking the types of values that may be contained within each field (Type A Level 2 as defined in
31、ISO/IEC 29109-1:2009), and tests of semantic assertions (Type A Level 3 as defined in ISO/IEC 29109-1:2009). This part of ISO/IEC 29109 does not establish tests of conformance of CBEFF structures embedding ISO/IEC 19794-2:2005 biometric data blocks (BDBs), tests of other characteristics of biometric
32、 products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), tests of conformance of systems that do not produce ISO/IEC 19794-2:2005 records, or tests for Level 3 conformance testing. 2 Conformance Biometric data interchange format conformance test

Specifically, they 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. Imple
