对于生物识别系统和生物识别系统的生物识别性能安全评估和演示攻击检测，本文件规定: -将安全功能组件扩展到ISO/IEC 15408-2中的SFR类； -ISO/IEC 18045中规定的ISO/IEC 15408-3 SAR等级方法的补充活动。 本文件介绍了生物识别系统安全评估的一般框架，包括扩展的安全功能组件，以及方法的补充活动，这是评估人员处理这些活动的附加评估活动和指导/建议。补充评估活动在本文件中制定，详细建议在ISO/IEC 19989-2（生物识别方面）和ISO/IEC 19989-3（呈现攻击检测方面）中制定。 本文件仅适用于单一生物特征类型的脚趾。但是，允许从SFR中的多个特性中选择一个特性。

For security evaluation of biometric recognition performance and presentation attack detection for biometric verification systems and biometric identification systemsthis document specifies: — extended security functional components to SFR Classes in ISO/IEC 15408-2; — supplementary activities to methodology specified in ISO/IEC 18045 for SAR Classes of ISO/IEC 15408-3. This document introduces the general framework for the security evaluation of biometric systems, including extended security functional components, and supplementary activities to methodology, which is additional evaluation activities and guidance/recommendations for an evaluator to handle those activities. The supplementary evaluation activities are developed in this document while the detailed recommendations are developed in ISO/IEC 19989-2 (for biometric recognition aspects) and in ISO/IEC 19989-3 (for presentation attack detection aspects). This document is applicable only to TOEs for single biometric characteristic type. However, the selection of a characteristic from multiple characteristics in SFRs is allowed.
