Paper Abstract
The rapid development of IT and WWW technique, causing person frequently confronts with various kinds of authorized
identification problem, especially the copyright problem of digital products. The digital watermarking technique was
emerged as one kind of solutions. The balance between robustness and imperceptibility is always the object sought by
related researchers. In order to settle the problem of robustness and imperceptibility, a novel adaptive multi-resolution
combined digital image watermarking algorithm was proposed in this paper. In the proposed algorithm, we first
decompose the watermark into several sub-bands, and according to its significance to embed the sub-band to different
DWT coefficient of the carrier image. While embedding, the HVS was considered. So under the precondition of keeping
the quality of image, the larger capacity of watermark can be embedding. The experimental results have shown that the
proposed algorithm has better performance in the aspects of robustness and security. And with the same visual quality,
the technique has larger capacity. So the unification of robustness and imperceptibility was achieved.
