Systems Security Certified Practitioner (SSCP) — Question 37

What is called the percentage of valid subjects that are falsely rejected by a Biometric Authentication system?

Answer options

• A. False Rejection Rate (FRR) or Type I Error
• B. False Acceptance Rate (FAR) or Type II Error
• C. Crossover Error Rate (CER)
• D. True Rejection Rate (TRR) or Type III Error A

Correct answer: A

Explanation

The correct answer is A, as the False Rejection Rate (FRR) specifically refers to the percentage of genuine users who are mistakenly rejected. The other options describe different metrics: B refers to the False Acceptance Rate (FAR), which measures false positives, C is the Crossover Error Rate (CER), and D refers to the True Rejection Rate (TRR), which is not a standard term in this context.
