National bodi
13、es 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 collaborate in fields of mutual interest. Other i
14、nternational 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 drafted in accordance with the rules gi
15、ven 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 International Standard requires approval
16、 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 for identifying any or all such patent rights. ISO/IEC 29109-2 was prepared by Join
17、t Technical Committee ISO/IEC 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: Generali

20、ording, 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 ISO/IEC 29109 defines tests for checking
21、 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 for achieving interoperability among implem
22、entations; 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 of the ISO/IEC 19794 requirements (coveri
23、ng 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 conformance testing methodology. This part
24、 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. Thus, it is intended to: establish elem
25、ents 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 test methods for measuring conformity of pr
26、oducts 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 development and use of conformity test method speci
27、fications, 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 method specifications and test method imple
28、mentations.

29、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 assertions of the structure of the finger
30、 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 ISO/IEC 29109-1:2009), and tests of semant
31、ic 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 products or other types of testing of bio
32、metric 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 tests conform to this part of ISO/IEC 29109 if
33、 they satisfy all of the normative requirements related to Clause 6. 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. Implementations of ISO/IEC 19794-2:2005 tested
34、according to the methodology specified shall be able to claim conformance only to those Biometric Data Record (BDR) requirements specified in ISO/IEC 19794-2:2005 that are tested by the test methods established by this methodology.
