Audio watermarking using echo hiding has fairly good perceptual quality. However, security and the tradeoff between robustness and imperceptibility are still relevant issues. This paper presents the echo hiding scheme in which the analysis-by-synthesis approach, interlaced kernels, and frequency hopping are adopted to achieve high robustness, security, and perceptual quality. The amplitudes of the embedded echoes are adequately adapted during the embedding process by considering not only the… CONTINUE READING
