This paper presents a novel patchwork audio watermarking scheme with a psychoacoustic model of HAS in DFT domain that has significantly higher detection robustness compared to standard and modified patchwork watermarking algorithms. In addition, watermark is perceptually tuned, so that its embedding is transparent. The proposed algorithm can be used for transmitting hidden data through telephone channel. Experimental results show that the proposed watermarking algorithm is sustainable against compression algorithms such as MP3, LPF, resampling, requantization and AWGN attacks.
