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.
Answer / guest
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.
