When might an organization using biometrics choose to allow a higher FRR instead of a higher FAR?
Answer Options
When security is more important than usability
When false rejection is not a concern due to data quality
When the CER of the system is not known
When the CER of the system is very high
Correct Answer: A
Explanation
Organizations that have very strict security requirements that don't have a tolerance for false acceptance want to lower the false acceptance rate, or FAR, to be as near to zero as possible. That often means that the false rejection rate, or FRR, increases. Different biometric technologies or a better registration method can help improve biometric performance, but false rejections due to data quality are not typically a concern with modern biometric systems. In this case, knowing the crossover error rate, or CER, or having a very high CER doesn't help the decision.
