An efficient and robust zero-watermarking scheme for digital audio

Abstract

A zero-watermarking algorithm for audio based on Linear Prediction Cepstrum Coefficients (LPCC) with sinc weighting function, is proposed herein. Using the correlation of LPCC with weighted factor, it can retrieve the available embedded watermarking back after various attacks. Simulation results demonstrate that the proposed algorithm has greater robustness and security than the LPCC scheme algorithm with linear weighting function.
