We propose a data hiding algorithm for stereo audio signals which embeds data using the polarity of the reverberations added to the high-frequency channels. We replace the high-frequency components with one middle channel, and embed data as the polarity of reverberations added to each channel in order to adjust the coherence between these channels. Blind detection of embedded data is possible using...
We investigated the accuracy of estimated synchronization positions for audio digital watermarking using the modified patchwork algorithm (MPA) on analog channels. We focused our efforts on synchronization since correct synchronization of DCT frames is crucial for watermark detection using this algorithm. We employed M-sequence synchronization patterns, and embedded this pattern as synchronization...
The authors propose a watermarking algorithm for stereo audio signals which embeds data using delay values of the high frequency channel signals. Since the stereo image perception of the human auditory system is known to be relatively insensitive to phase in high frequency regions, we replace the high frequency components with one middle channel, and embed data as delay between the channels. Blind...
