A content dependent spatially localized video watermark for resistance to collusion and interpolation attacks
Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205)
This paper presents a novel video watermarking algorithm based on two key ideas: statistical invisibility and contentsynchronized placement. We argue that statistical invisibility is essential to protect video watermarks from statistical collusion, and present a natural way to induce this property using a content-dependent spatially localized watermarking framework. We introduce the notion of a watermark footprint, the spatial locations over which its energy is spread.
