1 Scope
This International Standard addresses — fundamental requirements for planning and execution of environmental performance evaluations for biometric systems based on scenario and operational test methodologies, — specifications to define, establish, and measure specific conditions to assess, including requirements for equipment, — requirements for establishing a baseline performance in order to compare the influence of environmental parameters, — a specification of the biometric evaluation including requirements for test population, test protocols, data to record, and test results, and — procedures for carrying out the overall evaluation. This International Standard does not — determine which parameters should be analysed for a specific biometric modality (This is currently covered in ISO/IEC/TR 19795-3.), — specify requirements to perform a vulnerability analysis modifying environmental factors (This is covered by ISO/IEC 19792.), — classify biometric systems upon performance against different environmental conditions, or — specify requirements for determining the functional effects of environmental conditions on hardware components (such as corrosion, electrical interference, breakage, etc.) of biometric systems.
2 Conformance
Environmental tests of biometric systems shall be based on scenario evaluations or operational evaluations. Scenario evaluations shall conform with mandatory requirements of Clause 7 whereas operational evaluations shall conform with mandatory requirements of Clause 8. Further, a scenario evaluation that conforms to this International Standard shall analyse at least two evaluation conditions: the reference evaluation environment and one target evaluation environment. Both shall consider at least one environmental parameter to assess such as temperature, humidity, illumination, etc. These evaluation conditions shall be selected, specified, measured, and recorded in accordance with Clause 6.
4 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 19795-1 and the following apply. 4.1 ambient conditions real environment common, prevailing, and uncontrolled atmospheric and weather conditions in a room or place Note 1 to entry: A test described as “conducted at ambient conditions” was performed at whatever conditions were prevailing at that time on that day. 4.2 baseline performance performance of a biometric system in a reference evaluation environment 4.3 controlled conditions climatic and physical conditions that are constrained or managed or kept within certain bounds for the testing purpose 4.4 environment generator specialized test equipment used to establish and maintain the controlled conditions of the test 4.5 environmental conditions all atmospheric parameters (e.g. temperature, humidity) and other physical and chemical phenomena (e.g. illumination) that can surround the biometric system and influence in its performance Note 1 to entry: These can be controlled or ambient. 4.6 evaluation condition environmental condition under which an evaluation is executed 4.7 evaluation configuration physical layout of the environment in which the biometric system is going to be tested including the necessary equipment and test instruments for performing tests 4.8 evaluation environment environment in which the biometric system is evaluated considering the environmental conditions and the evaluation configuration 4.9 extreme condition condition that entails very high or very low values of the environmental parameters and may be hostile for systems operation or even human life 4.10 instrument calibrated equipment used to measure and/or record environmental parameters (such as temperature, humidity, illumination, and sound) Note 1 to entry: In some cases, instruments have the integrated capability of both measuring and recording parameters in one piece of equipment. 4.11 measuring point specific value for an environmental parameter that is being assessed 4.12 operational environment conditions under which the biometric system is expected to operate Note 1 to entry: This is a combination of environmental factors and operational procedures. 4.13 reference evaluation environment evaluation environment in which the biometric system is analysed to obtain baseline performance metrics 4.14 set point specific value for an environmental parameter that is being controlled 4.15 target evaluation environment evaluation environment in which the biometric system is analysed to obtain performance metrics for studying the influence of certain environmental conditions
