A Proposed Voice Encryption System Based on off-Line Ica Algorithm

Abstract

The voice encryption plays a great role in many important communication systems, such as military communication systems, a bank communication system. This paper proposes the possibility of application of analog voice encryption using adaptive signal processing technique called the Independent Component Analysis (ICA) technique. Practically the devoice encryption process is implemented using the JADE algorithm that can be considered as an Off-Line mode of ICA technique, and taking into consideration the testability of many input speech signals in Arabic and English. The objective test using LPC and SNR is applied to evaluate the proposed System.
