Influential Factors to Performance
Synonym
Definition
Factors that influence biometric performance. They can be discussed from the following viewpoints: characteristics of users (including the definition of impostors) and restrictions that come from practical situations in which that biometric modality is used in applications.
Introduction
When evaluating performance of biometric systems, factors that influence performance ("influencing factors") should be identified and analyzed because performance is greatly affected by a wide variety of influencing factors. The same biometric device may generate different test results if these influencing factors differ. Controlling, recording, and reporting factors are indispensable for executing repeatable performance tests and predicting operational performance [1-3].
