标准范围

本文档定义了生物识别认证上下文（ACBio）的结构和数据元素，其用于检查在远程站点执行的生物识别注册和验证过程的结果的有效性。本文档允许任何ACBio实例伴随任何与注册和验证相关的生物识别过程。ACBio规范不仅适用于单模态生物特征登记和验证，也适用于多模态融合。本文档中未提供表示攻击检测的实时信息。BPU报告中只能包含表示攻击检测（PAD）机制的保证信息。生物特征识别超出了本文档的范围。本文档指定了ACBio实例的加密语法。ACBio实例的加密语法在本文档中定义，应用加密消息语法(CMS)模式中指定的数据结构，其具体值可以使用紧凑二进制编码来表示。本文档没有定义实体（如BPU、索赔者和验证者）之间使用的协议。它关注的完全是各种处理活动的ACBio实例的内容和编码。

This document defines 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 enrolment and verification process executed at a remote site. This document allows any ACBio instance to accompany any biometric processes related to enrolment and verification. The specification of ACBio is applicable not only to single modal biometric enrolment and verification but also to multimodal fusion. The real-time information of presentation attack detection is not provided in this document. Only the assurance information of presentation attack detection (PAD) mechanism can be contained in the BPU report.
Biometric identification is out of the scope of this document.
This document specifies the cryptographic syntax of an ACBio instance. The cryptographic syntax of an ACBio instance is defined in this document applying a data structure specified in Cryptographic Message Syntax (CMS) schema whose concrete values can be represented using a compact binary encoding. This document does not define protocols to be used between entities such as BPUs, claimant, and validator. Its concern is entirely with the content and encoding of the ACBio instances for the various processing activities.
