标准范围

ISO/IEC 19794-7:20 21本文件规定了使用数字化平板电脑或高级笔系统等设备以多维时间序列形式捕获的签名/签名行为数据的数据交换格式。数据交换格式是通用的，因为它们可以在涉及手写标志或签名的广泛应用领域中应用和使用。本文档中没有涉及特定于应用程序的要求或功能。本文件包含:-可以捕获哪些数据的描述；-用于包含数据的三种二进制数据格式:用于一般使用的完整格式、能够保存与完整格式相同数量的信息但以压缩形式的压缩格式、以及用于智能卡和其他令牌的紧凑格式，其不需要压缩/解压缩但传达的信息少于完整格式；-XML模式定义；和-数据记录内容示例和捕获最佳实践。指定本文档中定义的哪些格式类型和哪些选项将应用于特定应用程序超出了范围；这需要在特定于应用程序的需求规范或应用程序配置文件中定义。建议使用加密技术来保护存储和传输的生物特征数据的真实性、完整性和机密性；然而，这些规定超出了本文件的范围。本文件还规定了适用于本文件的一致性测试方法、测试断言和测试程序的要素。它建立了对本文档中定义的签名/签名时间序列数据格式（ISO/IEC 19794-1）和语义测试断言（ISO/IEC 19794-1中定义的A型3级）。本文件中规定的一致性测试方法并未建立:-生物识别产品的其他特性的测试或生物识别产品的其他类型的测试(例如，可接受性、性能、稳健性、安全性)；或-未产生声称符合本文件要求的数据记录的系统的一致性测试。

ISO/IEC 19794-7:2021 This document specifies data interchange formats for signature/sign behavioural data captured in the form of a multi-dimensional time series using devices such as digitizing tablets or advanced pen systems. The data interchange formats are generic, in that they can be applied and used in a wide range of application areas where handwritten signs or signatures are involved. No application-specific requirements or features are addressed in this document.
This document contains:
- a description of what data can be captured;
- three binary data formats for containing the data: a full format for general use, a compression format capable of holding the same amount of information as the full format but in compressed form, and a compact format for use with smart cards and other tokens that does not require compression/ decompression but conveys less information than the full format;
- an XML schema definition; and
- examples of data record contents and best practices in capture.
Specifying which of the format types and which options defined in this document are to be applied in a particular application is out of scope; this needs to be defined in application-specific requirements specifications or application profiles.
It is advisable that cryptographic techniques be used to protect the authenticity, integrity, and confidentiality of stored and transmitted biometric data; yet such provisions are beyond the scope of this document.
This document also specifies elements of conformance testing methodology, test assertions and test procedures as applicable to this document. It establishes test assertions on the structure and internal consistency of the signature/sign time series data formats defined in this document (type A level 1 and 2 as defined in ISO/IEC 19794-1) and semantic test assertions (type A level 3 as defined in ISO/IEC 19794-1).
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 claimed to conform to the requirements of this document.
