Abstract

This paper presented a novel watermarking method to protect copyrights for digital media. Firstly, a visual model is employed to calculate the block based just noticeable difference (JND) to control the embedding intensity to improve the transparency and robustness of watermarking. Then, two neighboring image blocks are selected each time in Hilbert scanning order, and transformed by discrete wavelet transform (DWT) respectively. Lastly, according to the JND and the watermark bit, the values of two corresponding detail sub-bands coefficients in DWT domain is adjusted to embed the watermark. In this algorithm, a couple of coefficients in two corresponding detail sub-bands can embed a bit of watermark sequence. This embedding method guarantees hiding enough copies of watermark into the host image and improves its performance. The experimental results show that the embedded watermark is invisible, and the algorithm is robust to general image processing operations. The conclusion is that the algorithm is effective and practical.
