Question 10 (practice exam 12) (additional)

FRR (False Rejection Rate)

The probability that a legitimate/authorized user will be incorrectly rejected by the biometric system.

FAR (False Acceptance Rate)

The probability that an unauthorized user will be incorrectly accepted by the biometric system.

FAR (False Acceptance Rate)

The rate that should be minimized to prevent unauthorized access.

High FRR consequence

Legitimate users are frequently denied access, leading to inconvenience and frustration.

High FAR consequence

Unauthorized users can easily gain access, compromising the security of the system.

FAR (False Acceptance Rate)

Represents a false positive in a biometric system, where an unauthorized user is incorrectly accepted as legitimate.

FRR (False Rejection Rate)

Represents a false negative in a biometric system, where a legitimate user is incorrectly rejected.

Priority in high-security environments

Minimizing FAR should take priority to prevent unauthorized access, even if it means a slightly higher FRR.
