An IS auditor, in evaluating proposed biometric control
devices reviews the false rejection rates (FRRs), false
acceptance rates (FARs) and equal error rates (ERRs) of
three different devices. The IS auditor should recommend
acquiring the device having the:
A. least ERR.
B. most ERR.
C. least FRR but most FAR.
D. least FAR but most FRR.
Answer / guest
Answer: A
Equal error rate is the percent of times the false rejection
and acceptance are equal. The lower the overall measure, the
more effective the biometric. Neither a higher false
rejection rate nor false acceptance rate is desirable.
