Nowadays, digital watermarking algorithms are widely applied to ownership protection and tampering detection of digital images. In this paper, a new reversible watermarking algorithm based on wavelet lifting scheme is proposed. In the algorithm, the image is firstly divided into some no-overlapping blocks, and then is performed wavelet lifting scheme on every block, watermarking data is embedded into the image according to the attribute of the sub-band LL1 of every block In order to guarantee the security of algorithm, chaotic system is used to shuffle the position of blocks, the interesting point and usefulness of the algorithm lies in that watermarked image can be exactly restored into the original image, and the watermarking is robust to cropping. The experimental results show the effectiveness of the scheme. |
