Evaluation methodology for analyzing environment influence in biometrics

Biometrics is a new technology that provides a secure identification, which is being used more and more these days. However, sensors and biometric systems are usually only tested by their own suppliers, and rarely an independent evaluation of these products is carried out. Also, when evaluating a biometric system/device, many factors that can affect its performance, are not even considered. This is the case of the environmental conditions, i.e. humidity, temperature, etc. In this paper, authors propose an evaluation methodology for measuring environmental factors influence in biometric products and their applications. This methodology describes factors, tools, requirements and procedures, needed to perform this kind of performance evaluations.
