What is the most important item to consider when examining biometric systems?

A. The crossover acceptance rate—the lower the number, the better the biometric system

B. The crossover error rate—the higher the number, the better the biometric system

C. The crossover acceptance rate—the lower the number, the better the biometric system

D. The crossover error rate—the lower the number, the better the biometric system

Solution

D. The crossover error rate is defined as a percentage in which a lower number indicates a better biometric system. It is the most important measurement when attempting to determine the accuracy of the system. Answer A is incorrect because there is no crossover acceptance rate. Answer B is incorrect because higher numbers are less accurate. Answer C is incorrect because, again, there is no crossover acceptance rate.
