Abstract

In this paper, the digital image watermarking algorithm based on lifting scheme wavelet transform and singular value decomposition (SDV) is proposed and performed on the transmission of the electricity price.It scrambles electricity price to get a set of random watermark signal sequence, uses the ideas about lifting scheme wavelet transform to split, predict and update the information, so as to achieve the image frequency resolution and greatly improve the speed of operation. And it utilizes singular value decomposition algorithm in the watermark embedding and extraction process,which makes invisibility and robustness simultaneously improved.By simulation with Matlab,it shows the algorithm has good validity.
