This paper presents a novel watermarking algorithm using prediction-based watermarking embedding and detection as a solution for protecting unauthorized copying of digital content. Unlike the direct sequence spread-spectrum-based watermarking methods, the delayed version of a modified original audio signal is used, which is obtained from the linear prediction analysis as a watermark signal. Experimental results show that the authors' watermarking scheme is robust against common signal processing attacks, such as mixdown, amplitude compression, time-scale modification, and compression.:
