信息技术生物特征数据交换格式第7部分:签名/签名时间序列数据

[中文适用范围]： 本文件规定了使用数字化书写板或先进笔系统等设备捕获的手写签名/符号行为数据的互换数据格式。 这些互换数据格式具有通用性，可用于涉及手写签名或符号的各种应用领域。 本文件未涉及特定应用程序的要求或特性。 本文件包括：——描述可以捕获的数据；——三种二进制数据格式：一种用于普通用途的完整格式，一种能够包含与完整格式相同信息量但以压缩形式存储的压缩格式，以及一种针对智能卡和其他令牌设计且不需要压缩/解压但传递的信息少于完整格式的紧凑格式；——一个XML方案定义；以及——数据记录内容示例和捕获最佳实践。 [外文原描述]： 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.
