本文件定义: -生物特征信息记录（BIR）的结构和数据元素； -确定符合CBEFF要求的标准或规范适用性的使用领域概念； -CBEFF用户格式的概念，这是一种已发布的BIR格式规范，符合CBEFF用户指定的CBEFF要求； -CBEFF用户格式定义中使用的一组CBEFF数据元素的抽象值和相关语义； 本文档描述了使用CBEFF数据元素定义CBEFF用户格式的方法，以指定BIR的结构，包括标准生物特征头（SBH）。 本文件还提供了在BIR中识别BDB格式的方法，但BDB格式的标准化和互操作性不在本文件的范围内。本文档提供了一个安全块（SB），作为BIR携带有关BIR中BDB加密和BIR自身完整性机制信息的手段。SBs的结构和内容不在本文件范围内。此外，BDB加密机制和BIR完整性机制的规范不在本文件的范围内。 本文档指定了从一种CBEFF用户格式到另一种CBEFF用户格式的转换。 以下内容不在本文件范围内: -CBEFF用户格式规范中使用的CBEFF数据元素抽象值的编码；和 -保护个人隐私，防止生物特征数据的不当传播和使用。

This document defines: — structures and data elements for biometric information records (BIRs); — the concept of a domain of use to establish the applicability of a standard or specification that conforms with CBEFF requirements; — the concept of a CBEFF patron format, which is a published BIR format specification that complies with CBEFF requirements, specified by a CBEFF patron; — the abstract values and associated semantics of a set of CBEFF data elements to be used in the definition of CBEFF patron formats; This document describes methods to define CBEFF patron formats using CBEFF data elements to specify the structure of BIRs, including the standard biometric headers (SBHs). This document also provides the means for identification of BDB formats in a BIR, but the standardization and interoperability of BDB formats is not within the scope of this document. This document provides a security block (SB) as a means for BIRs to carry information about the encryption of a BDB in the BIR and about integrity mechanisms applied to the BIR itself. The structure and content of SBs is not within the scope of this document. Further, the specification of encryption mechanisms for BDBs and of integrity mechanisms for BIRs is not within the scope of this document. This document specifies transformations from one CBEFF patron format to a different CBEFF patron format. The following are not within the scope of this document: — the encoding of the abstract values of CBEFF data elements to be used in the specification of CBEFF patron formats; and — protection of the privacy of individuals from inappropriate dissemination and use of biometric data.
