BS ISO/IEC 29197:2015 pdf download-Information technology — Evaluation methodology for environmental influence in biometric system performance.
6.3.1 General The selection of the evaluation conditions entails two activities. Firstly, the parameters to be assessed and/or controlled shall be defined and reported depending on the type of biometric evaluation (e.g. temperature, humidity). This decision is mainly based on the biometric modality of the system under test as well as the type of technology used by its capture sensor. These parameters shall be selected by parties involved in the evaluation. NOTE ISO/IEC/TR 19795-3 [1] lists environmental factors that can impact performance on a modality-by- modality basis. Then, the measuring points and set points shall be specified for the selected environmental parameters to assess and/or control respectively. This specification shall consider two aspects: the types of biometric performance evaluation (i.e. scenario or operational evaluation) and the different phases of the recognition process (i.e. enrolment and verification). This subclause establishes requirements to select the measuring and set points for both types of environments (i.e. target evaluation environment and reference evaluation environment) considering also the aspects above mentioned. NOTE Since it is mandatory for scenario test methodology to carry out evaluations to obtain the baseline performance apart from any other evaluation performed in the target evaluation conditions, these values can be specified for the reference evaluation environment and the target evaluation environments. 6.3.2 Reference evaluation environment for scenario evaluations The reference evaluation environment defines the values or ranges for different environmental parameters under which baseline performance data will be obtained in scenario evaluation. Evaluation conditions for this environment shall be specified for the environmental parameters to be assessed and controlled. The values shall be defined considering the values proposed for a standard environment in Annex A.
