Robust, transparent and high-capacity audio watermarking in DCT domain
A robust and transparent DCT-based blind audio watermarking scheme is presented. Unperceivable watermarking is a performed subject to an auditory masking constraint. The payload capacity can reach as high as 848bps. 100% Recovery of the watermark is guaranteed for non- and minor-attack conditions. This scheme can even survive lowpass filtering with a cutoff frequency of 500Hz.
