| Abstract: | The auther Presents the modified patchwork algorithm(MPA), a statistical technique for audio watermarking algorithm in the transform(not only DCT, but also DFT and DWT),The MPA is sufficiently robust to withstand some attacks defined by SDMI. Experimental results show that the proposed watermarking algorithm is sustainable against compression algorithms as well as common signal processing manipulation attacks. |
