Abstract :
The embedding of a digital watermark into digital data protects the owners of information. The development of the Internet has made the problem of unauthorized copying and distributed data potentially devastating to intellectual property rights. A zero-watermarking algorithm for audio based on the correlation of Linear Prediction Cepstrum Coefficients (LPCC) with adaptive factors, is proposed herein. Compared with LPCC watermarking, the proposed algorithm can retrieve the available embedded watermark back after various attacks. Simulation results reveal that the proposed algorithm has greater robustness and security than the LPCC scheme algorithm.
