9、ISO/IEC 2010 All rights reservedForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of Intern
10、ational 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 international organizations, governmental and non-governmental, in liaison
11、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 given in the ISO/IEC Directives, Part 2. The main task of the joint technica
12、l 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 by at least 75 % of the national bodies casting a vote. Attention is draw
13、n 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 consists of the following parts, under the general title Information technology Conformance test
14、ing methodology for biometric data interchange formats defined in ISO/IEC 19794: Part 1: Generalized conformance testing methodology Part 2: Finger minutiae data Part 4: Finger image data Part 5: Face image data Part 6: Iris image data Part 8: Finger pattern skeletal data Part 9: Vascular image data
15、 Part 10: Hand geometry silhouette data The following parts are under preparation: Part 7: Signature/sign time series data Part 14: DNA data ISO/IEC 29109-10:2010(E) ISO/IEC 2010 All rights reserved vIntroduction ISO/IEC 19794-10:2007 specifies a data record interchange format for recording, storing
16、, and transmitting one or more hand geometry silhouette records. This part of ISO/IEC 29109 establishes tests for checking the correctness of the binary record. The objective of ISO/IEC 19794-10:2007 cannot be completely achieved until biometric products can be tested to determine whether they confo
17、rm 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 addressed
18、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 19794 Da
19、ta 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 hand geometry silhouette data according to ISO/IEC 19794-10:2007. It defines a testing methodology to ensure c
20、onformance of a vendors application or service to ISO/IEC 19794-10:2007. Thus this part of ISO/IEC 29109 is intended to: establish elements of the Conformance Testing Methodology framework that are specific to the Hand Geometry Silhouette-based Data Record requirements of ISO/IEC 19794-10:2007 confo
21、rmance testing, define requirements and guidelines for specifying confor mance test suites and related test methods for measuring conformity of products and services to the Hand Geometry Silhouette Data Record requirements of ISO/IEC 19794-10:2007, and define testing and reporting procedures to be f
22、ollo 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 19794-10:2007 records, and conformance testing programs for ISO/IEC 19794-10:2007 conformant produc
23、ts. 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. The table of assertions in Clause 6 specifies levels of testing for the conformance requirements of ISO/IEC 19794-10:2007. INTERNAT

25、 testing methodology, test assertions, and test procedures as applicable to ISO/IEC 19794-10. This part of ISO/IEC 29109 establishes test assertions of the struct ure of the hand geometry silhouette data format as specified in ISO/IEC 19794-10:2007 (Type A Level 1 as defined in ISO/IEC 29109-1:2009)

27、ined in ISO/IEC 29109-1:2009). This part of ISO/IEC 29109 does not establish test of conformance of CBEFF stru ctures required by ISO/IEC 19794-10:2007, test of consistency with input biometric data record (Level 3 as defined in ISO/IEC 29109-1:2009), test of other characteristics of biometric produ
