A Multi-sprite Based Anaglyph 3D Video Watermarking Approach Robust Against Collusion

3D video watermarking is far from the maturity of watermarking algorithms dedicated to audio, image or 2D video. In fact, little work has been proposed for anaglyph 3D videos. Such methods have not been robust against malicious attacks such as compression and collusion. The latter one is a very dangerous attack that can be applied on video content and can easily remove an embedded signature to obtain original content. This paper proposes an efficient approach for anaglyph 3D videos which can resist this malicious attack thanks to the use of a static multi-sprite generated from the different sets of frames which compose the original video. First, a sprite is generated for every set of 25 frames. Then every sprite is marked using a hybrid scheme: the discrete wavelet transform based algorithm and the middle significant bit technique, which improve signature invisibility and enhance robustness. Finally, a marked anaglyph 3D video is generated from every marked sprite. The use of multi-sprites as an embedding target provides robustness against collusion attacks and a high quality of marked video reconstruction compared with static mosaics. The experimental results show good robustness against collusion, compression and other attacks such as geometric manipulation and temporal attacks. Besides, the proposed technique presents a high level of invisibility.

An Overview of Digital Video Watermarking

The illegal distribution of a digital movie is a common and significant threat to the film industry. With the advent of high-speed broadband Internet access, a pirated copy of a digital video can now be easily distributed to a global audience. A possible means of limiting this type of digital theft is digital video watermarking whereby additional information, called a watermark, is embedded in the host video. This watermark can be extracted at the decoder and used to determine whether the video content is watermarked. This paper presents a review of the digital video watermarking techniques in which their applications, challenges, and important properties are discussed, and categorizes them based on the domain in which they embed the watermark. It then provides an overview of a few emerging innovative solutions using watermarks. Protecting a 3D video by watermarking is an emerging area of research. The relevant 3D video watermarking techniques in the literature are classified based on the image-based representations of a 3D video in stereoscopic, depth-image-based rendering, and multi-view video watermarking. We discuss each technique, and then present a survey of the literature. Finally, we provide a summary of this paper and propose some future research directions.

Two Kinds of Digital Video Watermarking Algorithm Implement and Compare

With the rapid development of multimedia technology, large amounts of digital information turn into easy storage and transmission, at the same time, copyright protection and authentication become a problem to be solved. Digital Video is composed of a series of continuous static images, because of its own characteristic, general image watermarking technology is difficult to direct extension to the video signal. In this paper, by using DCT transform and DWT transform, combined with the mean quantization algorithm, using three dimensional frequency domain transformation, introduces two kinds of transformation to the 3D video watermarking technology, utilize the quantitative test method to prove the existence of the watermark, and through the attacked experiments to verify the low complexity and well imperceptibility and robustness about the video watermarking algorithm.
