Abstract. In this paper, we propose a practical real-time video watermarking scheme for downscaling attack. We embed watermark into an arbitrary size of a host video and extract it...

The sensitivity attack is considered as a serious threat to the security of spread-spectrum-based schemes, since it provides a practical method of removing watermarks with minimum ...

Image-Adaptive watermarking systems exploit visual models to adapt the watermark to local properties of the host image. This leads to a watermark power enhancement, hence an improv...

Presently, almost all of the watermarking algorithms resistant to geometric attacks are dependent on the synchronization. In this paper, a geometrically robust watermarking scheme...

Watermarkingwith both obliviousdetection and high robustness capabilities is still a challenging problem. The existing methods are either robust or oblivious, but it is di cult to...
