Abstract

The secured biometric templates play an important role in real applications of recognition system             to generate revocable biometric templates. This paper introduces a proposed technique in cancelable biometrics that is used for speaker recognition. In this technique, zero cancelation digital filters are used to decode the extracted user features, intentionally. The objective of this work is to generate protected templates of speech signals. Simulation results  reveal the possibility of recognizing speakers in spite of feature deterioration due to the digital filtering effect which based on zero cancelation. Consequently, the robustness of the proposed speaker recognition system is guaranteed.
