scope:

This document supports evaluation of the accuracy, secrecy, and privacy of biometric template protection schemes. It establishes definitions, terminology, and metrics for stating the performance of such schemes. Particularly, this document establishes requirements for the measurement and reporting of:

- theoretical and empirical accuracy of biometric template protection schemes,

- theoretical and empirical probability of a successful attack on biometric template protection schemes (single or multiple), and

- the information leaked about the original biometric when one or more biometric template protection schemes are compromised.

This document also gives guidance on measuring and reporting diversity and unlinkability of templates.

This document does not:

- establish template protection schemes;

- address testing of traditional encryption schemes.
