biometric template protection; privacy enhancing technology

Over the past decades, a number of methods have been reported in the scientific literature to protect the privacy of biometric information stored in biometric systems. Keyless Biometric Template Protection (KBTP) methods aim to protect biometric information without the use of long-term secrets by deploying one-way functions. These KBTP methods are currently developed to an extent that commercial products have become available. When assessing and comparing different KBTP methods it is important to have a common and generic approach. Therefore, in this paper we present a reference framework that can be used in assessing and comparing the privacy properties of KBTP systems.
