The diagram shown next explains which of the following concepts:

A.
Crossover error rate.

B.
Type III errors.

C.
FAR equals FRR in systems that have a high crossover error rate.

D.
Biometrics is a high acceptance technology.

Explanation:
A: This rating is stated as a percentage and represents the point at which the false rejection rate equals the false acceptance rate. This rating is the most important measurement when determining a biometric systems accuracy.

(Type I error)rejects authorized individual
False Reject Rate (FRR)
(Type II error)accepts impostor
False Acceptance Rate (FAR)
