Biometric Techniques for Security (CY-503 (A)) - Important Questions

  1. Unit 114 Marks Medium Priority Asked: 2023

    Discuss in detail Biometric Authentication.

    Core broad-definition question appearing in past papers; tests foundational understanding of biometric authentication.

  2. Unit 17 Marks Medium Priority Asked: 2023

    Discuss the benefits of biometrics over traditional authentication systems.

    Directly derived from past-paper topics; compares biometrics with traditional authentication.

  3. Unit 17 Marks Medium Priority Asked: 2023

    Explain the key biometric terms and processes: enrollment, verification, identification, template, matcher and sensor.

    Tests core terminology and process knowledge that is essential for the unit and appeared in exam analytics.

  4. Unit 17 Marks Medium Priority Asked: 2023

    Describe various applications of biometric systems across different domains and discuss suitability considerations for each application.

    Covers applications-focused content noted in analytics; useful for applied scenario questions.

  5. Unit 110 Marks Low Priority

    Compare fingerprint, iris and facial recognition techniques: describe characteristics, advantages, limitations and suitable deployment scenarios for each.

    High-value comparative question recommended by exam pattern and past-paper trends (predicted).

  6. Unit 17 Marks Low Priority

    Explain biometric matching methods: minutiae-based, correlation-based, pattern-based and hybrid approaches, with examples of typical use-cases.

    Covers fundamental algorithmic approaches to matching; frequently asked conceptually though not found in the provided past papers.

  7. Unit 17 Marks Low Priority

    Define and explain performance metrics used in biometric systems: False Accept Rate (FAR), False Reject Rate (FRR), Equal Error Rate (EER), ROC and DET curves.

    Essential for performance evaluation questions; students must know standard metrics and their interpretations.

  8. Unit 110 Marks Low Priority

    Explain multi-biometric fusion: sensor-level, feature-level, score-level and decision-level fusion with advantages and challenges of each.

    Covers multi-biometric topics recommended in syllabus-style exams; appears in suggested high-value question lists.

  9. Unit 110 Marks Low Priority

    Describe the process for selecting an appropriate biometric for a given application and list key performance and privacy considerations that influence the choice.

    Practical selection and privacy considerations are often examined in application-oriented questions; recommended practice topic.

  10. Unit 17 Marks Low Priority

    Discuss privacy, legal and ethical issues in biometric data collection, storage and sharing. Explain template protection techniques such as cancellable biometrics and biometric cryptosystems.

    Addresses legal, ethical and template-protection concepts that increasingly feature in exam scenarios and assignments.
