Paper Abstract

This work considers the problem of frame collusion in video watermarking, one that is particularly relevant for this media due to the large collection of frames whose temporal inter-relationships may be exploited to facilitate estimation of the mark. Two new components are introduced: A mathematical framework for the statistical analysis of linear collusion and development of potential counterattacks; and a novel video watermarking approach employing the proposed strategies for robustness to collusion as well as other frame-as-image distortions. Experimental results demonstrating the performance of the proposed techniques against two types of collusion attacks are presented.
