本文件: -？建立生物识别系统性能测试的一般原则，包括性能测量、性能预测、性能比较，以及验证是否符合规定的性能要求； -？指定生物识别系统的性能指标； -？规定了试验数据记录和试验结果报告的要求；和 -？规定了测试协议的要求，以便: -？减少因数据收集或分析程序不当而产生的偏差； -？帮助实现对所付出努力的现场绩效的最佳估计； -？提高对测试结果适用范围的理解。 本文件适用于通过分析系统输出的比较分数和决策，对生物识别系统和算法进行经验性能测试，无需详细了解系统算法或感兴趣人群中生物特征的潜在分布。 对于故意试图破坏生物识别系统预期操作的人（例如，通过呈现攻击），错误和吞吐量的测量不在本文件的范围内。

This document: —    establishes general principles for testing the performance of biometrics systems in terms of error rates and throughput rates for purposes including measurement of performance, prediction of performance, comparison of performance, and verifying conformance with specified performance requirements; —    specifies performance metrics for biometric systems; —    specifies requirements on the recording of test data and reporting of test results; and —    specifies requirements on test protocols in order to: —    reduce bias due to inappropriate data collection or analytic procedures; —    help achieve the best estimate of field performance for the expended effort; —    improve understanding of the limits of applicability of the test results. This document is applicable to empirical performance testing of biometric systems and algorithms through analysis of the comparison scores and decisions output by the system, without requiring detailed knowledge of the system’s algorithms or of the underlying distribution of biometric characteristics in the population of interest. Not within the scope of this document is the measurement of error and throughput rates for people deliberately trying to subvert the intended operation of the biometric system (e.g. by presentation attacks).
