标准范围

ISO/IEC 24761:2009规定了生物识别认证上下文（ACBio）的结构和数据元素，用于检查在远程站点执行的生物识别验证过程的结果的有效性。ISO/IEC 24761:2009允许任何ACBio实例随附与验证和注册相关的任何生物识别过程中涉及的任何数据项。ACBio的规范不仅适用于单模态生物特征验证，也适用于多模态融合。ISO/IEC 24761:2009规定了ACBio实例的加密语法。ACBio实例的加密语法基于抽象的加密消息语法（CMS）模式，其具体值可以使用紧凑的二进制编码或人类可读的XML编码来表示。ISO/IEC 24761:2009没有定义在生物识别处理单元、索赔人和验证器等实体之间使用的协议。它完全关注各种处理活动的ACBio实例的内容和编码。

ISO/IEC 24761:2009 specifies the structure and the data elements of Authentication Context for Biometrics (ACBio), which is used for checking the validity of the result of a biometric verification process executed at a remote site. ISO/IEC 24761:2009 allows any ACBio instance to accompany any data item that is involved in any biometric process related to verification and enrolment. The specification of ACBio is applicable not only to single modal biometric verification but also to multimodal fusion. ISO/IEC 24761:2009 specifies the cryptographic syntax of an ACBio instance. The cryptographic syntax of an ACBio instance is based on an abstract Cryptographic Message Syntax (CMS) schema whose concrete values can be represented using either a compact binary encoding or a human-readable XML encoding. ISO/IEC 24761:2009 does not define protocols to be used between entities such as biometric processing units, claimant, and validator. Its concern is entirely with the content and encoding of the ACBio instances for the various processing activities.
