Enhanced Nested Video Watermarking Using Wavelets and Geometric Warping

Abstract

The amount of information created in the current era of information explosion is increasing in a overwhelming fashion. This increase in content has increased the awareness to protect the intellectual property. This paper presents one such method to protect Video content. The proposed watermarking hybrid scheme combines visual cryptography and wavelets to create a nested watermark, which is embedded into the raw uncompressed video signal using geometric warping technology. A block selection algorithm is used to select relevant area for embedding so as to improve robustness. The experimental resultsshowed that the proposed system shows significant improvement in terms of capacity and robustness against various attacks.
