ISO/IEC 29109-9:2011(E) iv ISO/IEC 2011 All rights reservedIntroduction ISO/IEC 19794-9:2007 specifies a data record interchange format for exchange of human vascular image data among systems within a Common Biometric Exchang
16、e Formats Framework (CBEFF) data structure. The data stored in a vascular data record often contains the metadata storing the subject-specific and image-specific, as well as the technology being used. This part of ISO/IEC 29109 establishes tests for checking the correctness of the binary record. Whe
17、n vascular image data is transmitted among systems, it can be interfered with by noise due to the transmission line. The received data might be incorrect during the exchange process. Therefore, there is a need to conduct conformance tests of commercial products to determine whether the data conform
18、to ISO/IEC 19794-9:2007 before using the data for other purposes. Vascular biometric technology is emerging or is under development by many research organizations. The vascular image resources are also being used by many vendors, who have utilized the vascular technology as a recognition or verifica
19、tion method in their systems. Currently, however, there is no standardized method for conducting conformance tests of vascular image data that supports ISO/IEC 19794-9:2007 during the exchange of vascular image data among systems. Application developers and implementers of different organizations ca
20、n interpret ISO/IEC 19794-9:2007 in different manners. Therefore, a standardized conformance testing methodology is necessary for achieving interoperability among implementations. This part of ISO/IEC 29109 supports those applications that require use of vascular image data according to ISO/IEC 1979
21、4-9:2007. It defines a testing methodology to ensure conformance of a vendors application or service to ISO/IEC 19794-9:2007. Thus, it is intended to: establish elements of the conformance testing methodology framework that are specific to the vascular image-based data record requirements of ISO/IEC
22、 19794-9:2007 conformance testing; define requirements and guidelines for specifying conformance test suites and related test methods for measuring conformity of products and services to the vascular image data record requirements of ISO/IEC 19794-9:2007; and define testing and reporting procedures
23、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 specifications, conformity test suites for ISO/IEC 19794-9:2007 records, and conformance testing programs for ISO/IEC 19794-9:2007 conformant pr
24、oducts. It is intended primarily for use by testing organizations, but can be applied by developers and users of test method specifications and test method implementations.

25、hodology for biometric data interchange formats defined in ISO/IEC 19794 Part 9: Vascular 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 19794-9. It specifies test assertions of the st
26、ructure of the vascular image data format as specified in ISO/IEC 19794-9:2007 (Type A Level 1 as defined in ISO/IEC 29109-1), test assertions of internal consistency by checking the types of values that can be contained within each field (Type A Level 2 as defined in ISO/IEC 29109-1). It does not s
27、pecify a test of conformance of CBEFF structures required by ISO/IEC 19794-9:2007, a test of consistency with an input biometric data record (Level 3), a test of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, sec
28、urity), a test of conformance of systems that do not produce ISO/IEC 19794-9:2007 records. 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 t
29、est 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 in this part of ISO/IEC 29109. Implementations of ISO/IEC 19794-9:2007 tested according to the specified methodology shall be able to claim conforman
30、ce only to those Biometric Data Record (BDR) requirements specified in ISO/IEC 19794-9:2007 that are tested by the test methods established by this methodology. Implementations of ISO/IEC 19794-9:2007 do not necessarily need to conform to all possible aspects of ISO/IEC 19794-9:2007, but only to tho
31、se ISO/IEC 19794-9:2007 requirements that are claimed to be supported by the implementation in an Implementation Conformance Statement (ICS), filled out in accordance with Clause 8 of ISO/IEC 29109-1:2009 and Table 1 in this part of ISO/IEC 29109.
