In biometric systems, the stored representation used for future comparisons is called the template.

• A. Scan data
• B. Key features
• C. Template
• D. None

Answer: (C)

The key idea is that biometric systems store a compact representation of a biometric sample to use for future matching. This stored representation, created during enrollment by extracting distinctive features from the biometric data, is called a template. When a new sample is presented, the system converts it into a comparable representation and compares it to the template using a matching algorithm and threshold. This approach lets the system verify identity efficiently and consistently, without keeping the raw, high-volume scan data. The term template is the standard way to refer to that stored representation used for future comparisons.
