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

  1. Unit 27 Marks Medium Priority Asked: 2023

    Discuss in detail Biometric Authentication.

    Core question from Unit 2 appearing in past paper.

  2. Unit 27 Marks Medium Priority Asked: 2022

    Smart cards and Biometrics.

    Direct extraction from past paper analytics (reference question).

  3. Unit 210 Marks Low Priority

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

    Core comparative topic from Unit 2 frequently set by examiners; synthesised from heatmap topics.

  4. Unit 210 Marks Low Priority

    Explain the process of enrollment, template storage, matching and decision making in a biometric system. Discuss security and privacy concerns associated with templates.

    Essential lifecycle question covering enrollment, storage and matching; high practical relevance for Unit 2.

  5. Unit 27 Marks Low Priority

    Define and differentiate False Accept Rate (FAR), False Reject Rate (FRR), Receiver Operating Characteristic (ROC) and Equal Error Rate (EER). Explain how these metrics are used to evaluate biometric systems.

    Standard evaluation-metrics question for biometric performance assessment.

  6. Unit 27 Marks Low Priority

    Describe fingerprint recognition: minutiae-based matching, characteristics, strengths, weaknesses, and typical applications.

    Focused technical question on fingerprint systems (minutiae-based matching and applications).

  7. Unit 27 Marks Low Priority

    Explain iris recognition: Daugman's iris code, matching process, strengths, weaknesses and deployment considerations.

    Focused technical question on iris recognition including Daugman's approach and deployment issues.

  8. Unit 210 Marks Low Priority

    Compare iris scan and retina vascular pattern: technical description, characteristics, strengths, weaknesses, and deployment scenarios.

    Comparative question between two ocular biometrics highlighted in the unit analytics.

  9. Unit 210 Marks Low Priority

    Describe liveness detection techniques and anti-spoofing measures for biometric systems. Discuss attack types and countermeasures.

    Security-focused question on anti-spoofing and liveness detection for biometric systems.

  10. Unit 210 Marks Low Priority

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

    Directly reflects heatmap suggestion on fusion levels; a typical multi-biometric question.

  11. Unit 27 Marks Low Priority

    Describe biometric template protection techniques: cancelable biometrics, biometric cryptosystems and secure sketch. Discuss trade-offs.

    Important for secure deployment: template protection mechanisms and trade-offs.

  12. Unit 210 Marks Low Priority

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

    Selection criteria question synthesised from unit learning outcomes and analytics heatmap.
