ISO/IEC 29109-6:2011(E) iv ISO/IEC 2011 All rights reservedIntroduction ISO/IEC 19794-6:2005 specifies a data record interchange format for recording, storing, and transmitting one or more iris images within a Common Biometric Exchange Formats Framework (CBEFF) data structure. E
16、ach 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 cannot be completely achieved until biometric products can be tested to determine wh
17、ether 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 methodology, test assertions, and test procedures as applicable to specific modal
18、ities 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 by the test suites will reflect the real degree of conformity of the implementati
19、ons 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 iris image data according to ISO/IEC 19794-6:2005. It defines a testing methodol
20、ogy 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 met hodology framework that are specific to the iris image-based data record requirements of IS
21、O/IEC 19794-6:2005 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 iris image data record requirements of ISO/IEC 19794-6:2005, and define testing and reporting procedure
22、s to be follo wed 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 records, and conformance testing programs for ISO/IEC 19794-6:2005 conformant
23、 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.

24、methodology for biometric data interchange formats defined in ISO/IEC 19794 Part 6: Iris image data 1 Scope This part of ISO/IEC 29109 specifies elements of conformance testing methodology, test assertions, and test procedures as applicable to ISO/IEC 19794-6:2005. This part of ISO/IEC 29109 establi
25、shes test assertions of the structure of the iris im age data format as specified in ISO/IEC 19794-6:2005 (Type A Level 1 as defined in ISO/IEC 29109-1:2009), test assertions of internal consistency by checking the types of values that may be contained within each field (Type A Level 2 as defined in
26、 ISO/IEC 29109-1:2009). This part of ISO/IEC 29109 does not establish tests of conformance of CBEFF structures required by ISO/IEC 19794-6:2005, semantic assertions (Type A Level 3 as defined in ISO/IEC 29109-1:2009), other characteristics of bi ometric products or other types of testing of biometri
27、c products (e.g. acceptance, performance, robustness, security), tests of conformance of systems that do not produce ISO/IEC 19794-6:2005 records. 2 Conformance Biometric data interchange format Conformance Test Suites (CTS) conform to this part of ISO/IEC 29109 if they satisfy all of the normative
28、requirements related to Clause 6 for one of the subformats defined in the base standard. Specifically, they shall use the test methodology specified in Clauses 6, 7 and 8 of ISO/IEC 29109-1:2009, and all Level 1 and Level 2 tests shall use the assertions defined in Table 2 or Table 3 of Clause 6 in
29、this part of ISO/IEC 29109. Implementations of ISO/IEC 19794-6:2005 tested according to the methodology specified shall be able to claim conformance only to those Biometric Data Record (BDR) requirements specified in ISO/IEC 19794-6:2005 that are tested by the test methods established by this method
30、ology. ISO/IEC 29109-6:2011(E) 2 ISO/IEC 2011 All rights reservedImplementations of ISO/IEC 19794-2:2005 do not necessarily need to conform to all possible aspects of ISO/IEC 19794-6:2005, but only to those ISO/IEC 19794-6:2005 requirements that are claimed to be supported by the implementation in a
