ISO/IEC 19795-2:20 07阐述了两种特定的生物识别性能测试方法:技术和场景评估。大多数生物特征测试属于这两种通用评估类型之一。技术评估通过先前收集的语料库来评估注册和比较算法，而场景评估通过实时处理从测试对象收集的样本来评估传感器和算法。前者旨在生成指示算法基本辨别能力的大量比较分数和候选列表。后者旨在测量模拟环境中的性能，包括测试对象-系统相互作用。 ISO/IEC 19795-2:20 07提供了针对两种主要评估类型的数据收集、分析和报告的要求和建议:技术评估和情景评估。 它规定了以下领域的要求: 制定和全面描述技术和情景评估的协议；执行和报告反映与生物测定评估类型相关联的参数的生物测定评估。

ISO/IEC 19795-2:2007 addresses two specific biometric performance testing methodologies: technology and scenario evaluation. The large majority of biometric tests are of one of these two generic evaluation types. Technology evaluations evaluate enrolment and comparison algorithms by means of previously collected corpuses, while scenario evaluations evaluate sensors and algorithms by processing of samples collected from Test Subjects in real time. The former is intended for generation of large volumes of comparison scores and candidate lists indicative of the fundamental discriminating power of an algorithm. The latter is intended for measurement of performance in modeled environments, inclusive of Test Subject-system interactions. ISO/IEC 19795-2:2007 provides requirements and recommendations on data collection, analysis and reporting specific to the two primary types of evaluation: technology evaluation and scenario evaluation. It specifies requirements in the following areas:

• development and full description of protocols for technology and scenario evaluations;
• execution and reporting of biometric evaluations reflective of the parameters associated with biometric evaluation types.
