19、ies a data record interchange format for storing, recording, and transmitting one or more face images within a Common Biometric Exchange Formats Framework (CBEFF) data structure. Each image is accompanied by subject-specific and image-specific metadata contained in a header record. This part of the
20、ISO/IEC 29109 multipart standard establishes tests for checking the correctness of the binary record.The objective of ISO/IEC 19794-5:2005 cannot be completely achieved until biometric products can be tested to determine whether they conform to those specifications. Conforming implementations are a
21、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 modalities addressed by each part of ISO/IEC 19794. The test assertions will cover
22、 as much as practical 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
23、 development of this conformance testing methodology.This part of ISO/IEC 29109 supports those applications that require use of face image data according to ISO/IEC 19794-5:2005. It defines a testing methodology to ensure conformance of a vendors application or service to the base ISO/IEC 19794-5:20
24、05 specification. Thus this document is intended to establish elements of the Conformance Testing Methodology framework that are specific to the Face Image-based Data Record requirements of ISO/IEC 19794-5:2005 conformance testing, define requirements and guidelines for specifying conformance test s
25、uites and related test methods for measuring conformity of products and services to the Face Image-based Data Record requirements of ISO/IEC 19794-5:2005, and define test procedures to be followed before, during, and after conformance testing.This standard is applicable to the development and use of
26、 conformity test method specifications, conformity test suites for ISO/IEC 19794-5:2005 records, and conformance testing programs for ISO/IEC 19794-5:2005 conformant products. It is intended primarily for use by testing organizations, but may be applied by developers and users of test method specifi
27、cations and test method implementations.

28、cifies elements of conformance testing methodology, test assertions, and test procedures as applicable to two-dimensional face images defined in the ISO/IEC 19794-5:2005 biometric data interchange format standard for face image data.This part of ISO/IEC 29109 establishes test assertions of the struc
29、ture of the face image data format as specified in ISO/IEC 19794-5:2005 (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 ISO/IEC 29109-1:2009).This part o
30、f ISO/IEC 29109 does not establish tests of conformance of 3D face records defined in ISO/IEC 19794-5:2005/Amd.2, tests of conformance of CBEFF structures required by ISO/IEC 19794-5:2005, tests of consistency with the input biometric data record (Level 3), tests of conformance of the image data to
31、the quality-related specifications of ISO/IEC 19794-5:2005, tests of conformance of the image data blocks to the respective JPEG or JPEG 2000 standards, tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, sec
32、urity).2 ConformanceBiometric data interchange format conformance tests conform to this part of ISO/IEC 29109 if they satisfy all of the normative requirements related to Clause 6. Specifically, they shall use the test methodology specified in Clauses 6, 7 and 8 of ISO/IEC 29109-1, and all Level 1 a
33、nd Level 2 tests shall use the assertions defined in Table 2 of this part of ISO/IEC 29109.Implementations of ISO/IEC 19794-5:2005 tested according to the methodology specified shall be able to claim conformance only to those biometric data record requirements specified in ISO/IEC 19794-5:2005 that
34、are tested by the test methods established by this methodology.Implementations of ISO/IEC 19794-5:2005 do not necessarily need to conform to all possible aspects of ISO/IEC 19794-5:2005, but only to those ISO/IEC 19794-5:2005 requirements that are claimed to be supported by the implementation in an
