Improving Robustness of Digital Video Watermarking Scheme through Random Frame Selection Algorithm

Abstract

Recently, research on digital video watermarking techniques either to permit or deny the use of copyright service has acquired much attention. A video is a sequence of inter-connected frames, thus embedding the watermark should be planned accurately and keep the hacking process more complex is very essential. Selection of random frames for inserting the watermark in a video decides the robustness against frame attacks like frame reduction, frame averaging and frame dropping. This paper proposes a Random Frame Section algorithm to embed a watermark dynamically without compromising its quality during frame selection process and Lucas algorithm to improve its robustness. The experimental analysis demonstrates the effectiveness and applicability of our approach. The outcomes confirm that the proposed method shows optimal result and robust against various frame based attacks.
