Introduction

GB/T 29268 "Information Technology Biometrics Performance Test and Report" is proposed to consist of seven parts.

--- Part 1.Principles and frameworks. The purpose is to define general principles and frameworks for testing and reporting the performance of biometric systems.

--- Part 2.Test methods for technical and scenario evaluation. The purpose is to specify techniques and scenarios in biometric performance testing

Biometrics performance testing covers three types. technical testing, scenario testing, and operational testing. Technical testing is based on biological characteristics

The performance test of the biometric identification system based on the signature sample database; the scenario test refers to the establishment of test objects according to the distribution of the established testers, and the simulation of

Real application scenarios are tested, and factors such as failure to obtain biometric samples and registration failure of personnel in registration or identification transactions are considered.

elements, such as access control scenarios. Running the test refers to the test object composed of actual users to test in the actual application scenario. For testing

Testers, in general, are not known to correctly label the data. Operational evaluation differs from technical or scenario evaluation in that object-based,

Environments and system designs are no longer limited by the purpose of repeatable testing, but vary according to operational use. Examples of uncontrolled variables include primary

legality of individual identity claims, environmental influences from weather or lighting, or variability in the use of the system by different people.

GB/T 29268 regulates biometric performance testing and reporting from the above three test types, and specifies the original

This document specifies the test methods for the operational evaluation of biometric recognition performance, and its

The overall goal is to measure or monitor the performance of a biometric system over a period of time. Test items for running tests may include.

--- Determining whether performance meets specific application-specific requirements or supplier requirements;

--- Determine if the system needs to be tuned or configured to improve performance;

--- predict performance changes as the number of objects, locations or devices increases;

--- Obtain information about the target population and environmental parameters affecting system performance;

--- Obtain performance data from pilot implementations;

--- Obtain performance data to benchmark future systems.

1 Scope

This document.

--- Provide guidance for the operational testing of biometric identification systems;

--- specifies the performance indicators of the operating system;

--- Refinement of data that may be retained by the operating system to support performance monitoring;

--- Specifies the requirements for test methods, data recording and reporting of operational evaluation results.
