Question
The Crossover Error Rate (CER) is a good measure of performance for:
Options
- ABiometrics
- BTokens
- CKerberos
- DA fingerprint scan
- EDiscretionary access control
Explanation
The Crossover Error Rate (CER) is a key metric used to evaluate the overall accuracy and performance of biometric authentication systems.
Common mistakes.
- B. Tokens are physical or digital devices used for authentication and do not have performance metrics like CER, which is specific to biometric matching.
- C. Kerberos is a network authentication protocol that uses tickets, and its performance is measured by factors like latency or throughput, not error rates related to biometric scans.
- D. While a fingerprint scan is a biometric method, 'Biometrics' (choice A) is the broader and more accurate category for which CER is a general performance measure.
- E. Discretionary access control (DAC) is an authorization model where resource owners control access, and its performance is not evaluated using biometric error rates.
