0018-9162/00/$ 2000 IEEE56 ComputerAn Introduction toEvaluating Biometric SystemsOn the basis of media hype alone, you mightconclude that biometric passwords will soonreplace their alphanumeric counterpartswith versions that cannot be stolen, forgot-ten, lost, or given to another person. Butwhat if the performance estimates of these systems arefar more impressive than their actual performance?To measure the real-life performance of biometricsystems and to understand their strengths and weak-nesses better we must understand the elements thatcomprise an ideal biometric system. In an ideal system all members of the population possess the char-acteristic that the biometric identifies, like irisesor fingerprints; each biometric signature differs from all others inthe controlled population; the biometric signatures don t vary under the con-ditions in which they are collected; and the system resists evaluation quantifies how well bio-metric systems accommodate these , biometric evaluations require that an inde-pendent party design the evaluation, collect the testdata, administer the test, and analyze the designed this article to provide you with suffi-cient information to know what questions to
