Which one of the following is the MOST important in designing a biometric access system if it is
essential that no one other than authorized individuals are admitted?
A.
False Acceptance Rate (FAR)
B.
False Rejection Rate (FRR)
C.
Crossover Error Rate (CER)
D.
Rejection Error Rate
Disagree. This should be False Rejection Rate (FRR). If it is essential that a hacker does not get in then we do not want to falsely let her in (FAR). Right?
If a hacker were to get past the security mechanism, then that’s a false acceptance. This is what you want to lower. Therefore the answer is A. You don’t care what the false rejection rate is – whether it’s 0% or 100% has nothing to do with unauthorized individuals trying to get past.
Agree.
This question is written in a very confusing way …. not sure why overcomplicating the target of the question …. some questions feel like they were written by lawyers or contract people instead of engineers
I am changing my answer. A – Because it is FAR that I am concerned with.
Think of FAR as a false positive. Answer is A
If you need to keep your hands warm at a football game, pee in a bottle and hold it.
“it is essential that no one other than authorized individuals are admitted” – therefor the probability that the system incorrectly authorizes a non-authorized person (FAR) is most important.
