"Determining the best biometric system for a specific operational environment and how to set up that system for optimal performance requires an understanding of the evaluation methodologies and statistics used in the biometrics community. This document provides a baseline testing and statistics review, thus enabling appropriate analysis of available research reports. This document is intended to further the understanding of a general audience and is not intended to replace or compete with sources that may be more technically descriptive/prescriptive such as those under development by standards bodies such as INCITS and ISO/IED. Detailed information on how to properly perform performance evaluations is beyond the scope of this document."
