标准摘要
[中文适用范围]： 本文件规定了： - 用于表示虹膜图像数据的通用可扩展数据交换格式：基于ASN.1可扩展规范的标记二进制数据格式和基于XML模式定义的文本数据格式，两者都能够保存相同信息； - 数据记录内容的示例； - 数据采集的应用特定要求、建议和最佳实践； - 适用于本文件的符合性测试断言和符合性测试程序。 虹膜图像信息存储为： - 可选使用ISO/IEC 15948或ISO/IEC 15444-1压缩的强度值数组； - 可选使用ISO/IEC 15948或ISO/IEC 15444-1压缩的强度值数组，可以围绕虹膜裁剪，虹膜位于中心，并且可以包含非虹膜区域的感兴趣区域掩膜。 本文件还规定了符合性测试方法、测试断言和测试程序的元素，适用于本文件。 它建立了： - 关于虹膜图像数据格式结构的测试断言，如本文件第6、7、8和9条所述； - 关于内部一致性的测试断言，通过检查每个字段可能包含的值的类型； - 语义测试断言。 本文件规定的符合性测试方法不建立： - 生物识别产品的其他特性的测试或其他类型的生物识别产品测试（例如，接受、性能、鲁棒性、安全性）； - 不产生符合本文件要求的数据记录的系统的符合性测试。 本文件不建立： - 相机光学规格的要求； - 虹膜图像光度特性的要求； - 注册过程工作流程和使用虹膜设备的要求。 [外文原描述]： This document specifies: — generic extensible data interchange formats for the representation of iris image data: a tagged binary data format based on an extensible specification in ASN.1 and a textual data format based on an XML schema definition that are both capable of holding the same information, — examples of data record contents, — application specific requirements, recommendations, and best practices in data acquisition, and — conformance test assertions and conformance test procedures applicable to this document. The iris image information is stored as: — an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444-1, or — an array of intensity values optionally compressed with ISO/IEC 15948 or ISO/IEC 15444-1 that can be cropped around the iris, with the iris at the centre, and which can incorporate region-of-interest masking of non-iris regions. This document also specifies elements of conformance testing methodology, test assertions, and test procedures, as applicable to this document. It establishes: — test assertions pertaining to the structure of the iris image data format, as specified in Clauses 6, 7, 8 and 9 of this document, — test assertions pertaining to internal consistency by checking the types of values that may be contained within each field, and — semantic test assertions. The conformance testing methodology specified in this document does not establish: — tests of other characteristics of biometric products or other types of testing of biometric products (e.g. acceptance, performance, robustness, security), or — tests of conformance of systems that do not produce data records conforming to the requirements of this document. This document does not establish: — requirements on the optical specifications of cameras, or — requirements on photometric properties of iris images, or — requirements on enrolment processes, workflow and use of iris equipment.
