19、9109-5:2014(E) Introduction The ISO/IEC 19794-5:2005 standard specifies 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 ima
20、ge-specific metadata contained in a header record. This part of the 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 th
21、ey 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 modalities ad
22、dressed by each part of ISO/IEC 19794. The test assertions will cover 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
23、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 require use of face image data according to ISO/IEC 19794-5:2005. It defines a testing methodology to ensure conforma
24、nce of a vendors application or service to the base ISO/IEC 19794-5:2005 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
25、, define requirements and guidelines for specifying conformance test suites 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 conform
26、ance testing. This standard is applicable to the development and use of 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 organizat
27、ions, but may be applied by developers and users of test method specifications and test method implementations.

28、/IEC 19794 Part 5: Face image data 1 Scope This part of ISO/IEC 29109 specifies 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
29、 data. This part of ISO/IEC 29109 establishes test assertions of the structure 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
30、each field (Type A Level 2 as defined in ISO/IEC 29109-1:2009). This part of 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
31、biometric data record (Level 3), tests of conformance of the image data to 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
32、testing of biometric products (e.g. acceptance, performance, robustness, security). 2 Conformance Biometric 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 met
33、hodology specified in Clauses 6, 7 and 8 of ISO/IEC 29109-1, and all Level 1 and 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 t
34、hose biometric data record requirements specified in ISO/IEC 19794- 5:2005 that 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-
35、5:2005 requirements that are claimed to be supported by the implementation in an Implementation Conformance Statement, filled out in accordance with Clause 8 of ISO/IEC 29109-1 and Table 1 of this part of ISO/IEC 29109.
