Improved Video Watermarking Using Nested Watermark, Wavelets and Geometric Warping

Abstract

Abstract. The advancements in communication software and hardware is increasing the amount of information in the form of text, image, audio and video being shared. This increase arise the issue of protecting the intellectual property. This paper studies the protection of video signals through watermarking. The system proposed uses a combination of visual cryptography and wavelets to create a nested watermark which is embedded into the raw uncompressed video signal using a geometric warping technology. To improve robustness against compression, the method embeds the watermark in relevant area using a block selection method. The experimental results prove that the proposed system is efficient in terms of capacity and robustness against various attacks.

Quality analysis of distributed max-plus algebra based morphological wavelet transform

“…Future work will involve testing the proposed distributed data embedding-MMT watermarking scheme's resistance to various attacks as well as its application while taking various parameters [17]. In practice, quite high robustness can be attained with the optimal design, however it should be noted that robustness must always be balanced against the watermark data rate and imperceptibility, and the ideal tradeoff depends on the application.…”
