Abstract Robust watermarking is an effective method and a promising solution for securing protecting the copyright of digital images. Moments moment invariants have become popular tools robust due to their geometric invariance favorable capability image description. Many moments-based schemes been proposed. However, there challenging problem these that should be addressed. One problems improve ...

In this paper, an SVD-based perceptual fidelity metric is reviewed and used in the context of objective quantification of image watermarking fidelity for two stateof-the-art Image Adaptive SVD-based Watermarking Schemes. The proposed metric makes use of a Human Visual System perceptual model in the wavelet domain. The robustness of the watermarking schemes against JPEG compression and resizing ...

It is shown in this paper that, even with a non-invertible watermarking algorithm or an asymmetric watermarking protocol, it is still possible to effect an invertibility attack, which relies on a forged watermarking algorithm, a counterfeit mark, and a fake key. Two examples are given to show the vulnerability of the unfortified non-invertible algorithm/ asymmetric protocol. As a solution, a se...

In a digital watermarking scheme, it is not convenient to carry the original image all the time in order to detect the owner's signature from the watermarked image. Moreover, for those applications that require different watermarks for different copies, it is preferred to utilize some kind of watermark-independent algorithm for extraction process i.e. dewatermarking. Watermark embedding is perf...
