The template is based on ________ generated during enrollment scan.

• A. scan data
• B. Both A and B
• C. Neither A nor B
• D. key features

Answer: (D)

Templates are created from the most distinctive attributes extracted during the enrollment scan. When a biometric sample is captured, the system doesn’t store the full image; it analyzes the data to locate reliable, unique markers and encodes those markers as a compact template. These key features—such as minutiae points in a fingerprint or specific landmark patterns in other biometrics—provide a stable, efficient representation for matching. That’s why the template is based on key features generated during enrollment scan. The raw scan data isn’t stored as the template, and options implying otherwise don’t fit how templates are designed.
