LPC Prediction Error Combined with LSB Steganography for Blind Speech Authentication

In this paper, we propose a new blind speech authentication method to verify the authenticity and integrity of speech. In this method, linear predictive coding (LPC) and least significant bit (LSB) steganography are combined, using LPC prediction error (LPCPE) as invariable features of speech and in...

Summary:In this paper, we propose a new blind speech authentication method to verify the authenticity and integrity of speech. In this method, linear predictive coding (LPC) and least significant bit (LSB) steganography are combined, using LPC prediction error (LPCPE) as invariable features of speech and inserting these features into least significant bits of speech samples. When verifying the speech, we extract the inserted features, and compare them with recalculated LPCPE. Experimental results show that this method can detect not only the tampering in speech but also the position and region of the tampering
