This paper, based on three presentations at La Reconnaissance du Locuteur et ses Applications Commerciales et Criminalistiques (RLA2C) Workshop in Avignon, discusses the evaluation of speaker recognition systems from several perspectives. A general

Introduction to Evaluating Biometric Systems

February 21, 2000

Author(s)

P J. Phillips, Alvin F. Martin, Charles L. Wilson, Mark A. Przybocki

Biometric technology has the potential to provide secure access using user characteristics, biometric signatures, that cannot be lost, stolen, or easily duplicated. However, the actual performance of many existing systems is unknown. Potential users of

An Introduction to Evaluating Biometric Systems

February 1, 2000

Author(s)

P J. Phillips, Alvin F. Martin, Charles L. Wilson, Mark A. Przybocki

How and where biometric systems are deployed will depend on their performance. Knowing what to ask and how to decipher the answers can help you evaluate the performance of these emerging technologies. On the basis of media hype alone, you might conclude
