Which of the following error-rate combinations with a biometric entry control device provides the highest...

In biometric systems:

False Acceptance Rate (FAR) represents unauthorized access.

False Rejection Rate (FRR) represents inconvenience to legitimate users.

From a security perspective, a low FAR is more critical because it ensures that unauthorized individuals are not granted access. A higher FRR can be tolerated in high-security environments, as it affects convenience rather than security.

A (low/low) is ideal but harder to achieve.

C and D (high FAR) compromise security.
