Question
The BEST overall quantitative measure of the performance of biometric control devices is:

A. false rejection rate.
B. false acceptance rate.
C. equal error rate.
D. estimated error rate.
Answers
Answer: C

Low equal error rate (EER) is a combination of the low false rejection rate and the low false acceptance rate. EER, expressed as a percentage, is a measure of the number of times that the false rejection and false acceptance are equal. A low EER is the measure of the more effective biometrics control device. Low false rejection rates or low false acceptance rates alone do not measure the efficiency of the device. Estimated error rate is non-existing and hence irrelevant.   Your Comment
