For any or all biometric sample types as necessary, this part of ISO/IEC 29794

1. establishes terms and definitions that are useful in the specification, and use of quality metrics;

2. recommends the purpose and interpretation of biometric quality scores;

3. defines the format and placement of quality data fields in biometric data interchange formats;

4. suggests methods for developing biometric sample datasets for the purpose of quality score normalization; and

5. suggests a format for exchange of quality algorithm results.

Outside the scope are the following:

1. the specification of minimum requirements for sample, module, or system quality scores;

2. performance assessment of quality algorithms; and

3. standardization of quality algorithms.
