Digital watermarking has been considered as an important technique to protect the copyright of digital content. For a digital watermarking method to be effective, it is essential ...
We analyze several recent schemes for watermarking network flows based on splitting the flow into intervals. We show that this approach creates time dependent correlations that en...
A novel digital image watermarking method based on wavelet domain fractal coding is presented in this paper. Employing the invariant parameters of the wavelet domain fractal trans...
A new method improving watermark robustness against both global and local geometrical distortions is presented in this article. The proposed approach is based on a self-reference c...
Watermarking has been used on multimedia for a variety of applications, among which intellectual property protection stands out. However, and in spite of a growing need, very few a...
