Traditional criteria used in biometric performance evaluation do not cover all the performance aspects of biometric template protection (BTP) and the lack of well-deﬁned metrics inhibits the proper evaluation of such methods. Previous work in the literature focuses, in general, on a limited set of criteria and methods. This paper provides the ﬁrst holistic approach to the evaluation of biometric template protection that is able to cover a whole range of methods. We present a selection of well-deﬁned criteria and metrics that are compliant with the reference architecture for template protection as deﬁned in the recently adopted standard ISO/IEC 24745 (2011), which is applicable to nearly all known BTP methods. The metrics have been grouped in three categories of performance: technical, security and privacy, and operational. In addition, the visualization and representation of scores is discussed and a method for the uniﬁcation of scores is proposed.
