Watermarking Scheme

<p>This paper focuses on moving picture expert group ( MPEG) based digital video watermarking scheme for copyright protection services. The present work implemented the video watermarking technique in which discrete cosine transform (DCT) intermediate frequency coefficients from instantaneous decoder refresh (IDR) frames are utilized. The subset of IDR frames as candidate frames are chosen to reduces the probability of temporal synchronization attacks to achieve better robustness and high visual perceptual quality.  A secret key based cryptographic technique is used to enhance the security of embedded watermark. The proposed scheme embedded the watermark directly during the differential pulse code modulation (DPCM) process and extracting through decoding the entropy details. Three keys are required to extract the watermark whereas one of the key is used to stop the extraction process and the remaining two are used to display the watermark. The robustness is evaluated by testing spatial synchronization attacks, temporal synchronization attacks and re-encoding attacks. The present work calculates the simulation results that shows the watermarking scheme achieved high robustness against video processing attacks frequently occur in the real world and perceptibility also obtained without changing the motion vectors during the DPCM process of MPEG-2 encoding scheme.</p>

Watermarking Scheme

Digital watermarking has been proposed as very useful technology in the protection of digital data such as image, audio, video, formatted documents (PDF or PS), and 3D objects. In the literature, most of the existing watermarking approaches are conducted on images. However, video is even more useful and should be protected with higher priority. In particular, video sequences usually contain rich properties that images do not have. On the other hand, the types of attacks applied on a video are much different from those applied on an image. In this chapter, we will focus ourselves specifically on video watermarking. The content of this chapter is divided into two parts. In the first part, the existing video watermarking techniques are briefly reviewed. We have pointed out their advantages and disadvantages to realize what can be done about video watermarking. In the second part, we propose a compressed domain video watermarking scheme for copyright protection. For the sake of real-time video watermark detection, our method is directly conducted in the MPEG-2 bitstream. More specifically, watermarks are inserted into the VLC domain. We shall discuss how to select proper data in a video bitstream to embed watermarks while preserving perceptual fidelity. In addition, video watermarks are embedded by a new proposed watermarking technique, which is based on the concept of communications with side information. The power of our method is reflected by its robust capability against attacks. Future work will also be pointed out to further improve the current scheme

Copyright Violation

The growth of internet and its reachability to all sectors of people have never been greater. Internet has become the best marketplace, the best library and may be the best guide for everything. But this revolution comes with some bigger problems. One of the most challenging problems among them would be copyright protection of digital data being transferred over internet. Digital images, videos and audios undergo illegal re-production and re-distributions, tampering and other acts of copyright violation. This is proved to have leading the film and other prominent industries to loss of millions of dollars per year. Encrypting the data provides security to it. In this case only people who pay to buy the secret key that should be used for decryption can use the data. But the problem is that once decrypted, the data can be re-produced into any number of copies and can be re-distributed without any permission from the author. Watermarking is an intelligent solution for this problem where the presence of watermark can be checked to distinguish pirated copies from the actual ones. A lot of methods have been developed for image and video watermarking, but the research on audio watermarking started a little bit later. The reason might be the fact that audio watermarking is tedious compared to image and video as Human Auditory System (HAS) is more sensitive compared to Human Visionary System. So ensuring the imperceptibility of audio watermarks is a tougher task. In this thesis various audio watermarking schemes introduced so far in the literature and their merits and demerits are studied.

Similar to conventional video, the increasingly popular 360  virtual reality (VR) video requires copyright protection mechanisms. The classic approach for copyright protection is the introduction of a digital watermark into the video sequence. Due to the nature of spherical panorama, traditional watermarking schemes that are dedicated to planar media cannot work efficiently for 360  VR video. In this article, we propose a spherical wavelet watermarking scheme to accommodate 360  VR video. With our scheme, the watermark is first embedded into the spherical wavelet transform domain of the 360  VR video. The spherical geometry of the 360  VR video is used as the host space for the watermark so that the proposed watermarking scheme is compatible with the multiple projection formats of 360  VR video. Second, the just noticeable difference model, suitable for head-mounted displays (HMDs), is used to control the imperceptibility of the watermark on the viewport. Third, besides detecting the watermark from the spherical projection, the proposed watermarking scheme also supports detecting watermarks robustly from the viewport projection. The watermark in the spherical domain can protect not only the 360  VR video but also its corresponding viewports. The experimental results show that the embedded watermarks are reliably extracted both from the spherical and the viewport projections of the 360  VR video, and the robustness of the proposed scheme to various copyright attacks is significantly better than that of the competing planar-domain approaches when detecting the watermark from viewport projection.
