<title>Robust frame-dependent video watermarking</title>

Abstract

In this paper, we describe some of the problems associated with watermarking key management, with particular attention to the case of video. We also describe a possible solution to the problem, which is that of image-dependent watermarking, and briefly discuss some of the possible advantages to be gained from adopting such an approach. The paper also presents a simple, efficient means of robustly extracting bits from a video sequence. The algorithm has applications to secure, oblivious video watermark detection.
