Abstract: Biometric template protection techniques are able to provide a solution for vulnerability which compromises biometric template. These are expected to be useful for remote biometric authentication. However, there were no supported standard evaluation method, thus making these technology not fully trusted. The draft Recommendation ITU-T X.gep: 'A guideline for evaluating telebiometric template protection techniques' which is currently under development at ITU-T SG 17 Question 9 (telebiometrics) aims to fill this need. ITU-T X.gep describes a general guideline for testing and reporting the performance of biometric template protection techniques based on biometric cryptosystem and cancellable biometrics. This guideline specifies two reference models for evaluation which use biometric template protection techniques in telebiometrics system. Then, it defines the metrics, procedures, and requirements for testing and evaluating the performance of the biometric template protection techniques. In addition, this Recommendation ITU-T X.gep has been approved at April 2012, and pre-published as ITU-T X.1091.

Keywords: biometric template protection; biometrics cryptosystems; cancellable biometrics; performance evaluation; security performance; remote authentication; telebiometric templates; telebiometrics; cryptography.
