本文件: -建立测试生物识别系统在错误率和吞吐率方面的性能的一般原则，目的包括测量性能、预测性能、比较性能和验证是否符合指定的性能要求； -指定生物识别系统的性能度量； -规定了测试数据记录和测试结果报告的要求；和 -规定测试方案的要求，以便: -减少由于不适当的数据收集或分析程序造成的偏倚； -帮助实现对所付出努力的实地业绩的最佳估计； -提高对测试结果适用性限度的理解。 本文件适用于通过分析系统输出的比较分数和决策来进行生物识别系统和算法的经验性能测试，而不需要系统算法或unde的详细知识感兴趣人群中生物特征的分布。 对于故意试图破坏生物识别系统的预期操作（例如，通过呈现攻击）的人，测量错误和吞吐率不在本文档的范围内。

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).
