This paper addresses copyright protection as a major security demand in digital marketplaces. Two watermarking techniques are proposed and compared for compressed and uncompressed video with the intention to show the advantages and the possible weaknesses in the schemes working in the frequency domain and in the spatial domain. In this paper a robust video watermarking method is presented. This...

The growth of the Internet has frequently increased the availability of digital data such as text, audio, images and videos to the public. Digital watermarking is one of the important techniques to secure digital data in the field of authentication, copyright protection and security. The non-blind watermarking systems have a main problem that for extracting the watermark image from the watermar...

This paper proposes a unified approach to digital watermarking of images and video based on the twoand threedimensional discrete wavelet transforms. The hierarchical nature of the wavelet representation allows multiresolutional detection of the digital watermark, which is a Gaussian distributed random vector added to all the high-pass bands in the wavelet domain. We show that when subjected to ...

There has been a remarkable increase in the data exchange over web and the widespread use of digital media. The mounting interest with reference to digital watermarking throughout the last decade is certainly due to the increase in the need of copyright protection. Applications of video watermarking in copy control, broadcast monitoring, finger printing, video authentication, copyright protecti...

Present era shows a rapid growth in the progress of digitization and creation of digital multimedia content. Image and Video makes up the majority component in digital multimedia content. The potential solution for protection and prohibiting copyright infringement of multimedia is only using digital watermarks. The characteristic of robustness, i. e. , sustainable capability to withstand agains...

This work considers the problem of frame collusion in video watermarking, one that is particularly relevant for this media due to the large collection of frames whose temporal inter-relationships may be exploited to facilitate estimation of the mark. Two new components are introduced: A mathematical framework for the statistical analysis of linear collusion and development of potential countera...

This paper presents a novel video watermarking algorithm based on two key ideas: statistical invisibility and contentsynchronized placement. We argue that statistical invisibility is essential to protect video watermarks from statistical collusion, and present a natural way to induce this property using a content-dependent spatially localized watermarking framework. We introduce the notion of a...

This paper presents a video watermarking technology for broadcast monitoring. The technology has been developed at the Philips Research Laboratories in Eindhoven in the context of the European ESPRIT project VIVA (Visual Identity Veri cation Auditor). The aim of the VIVA project is to investigate and demonstrate a professional broadcast surveillance system. The key technology in the VIVA projec...

Digital watermarking is one of the important techniques to secure digital media files in the domains of data authentication and copyright protection. In the nonblind watermarking systems, the need of the original host file in the watermark recovery operation makes an overhead over the system resources, doubles memory capacity, and doubles communications bandwidth. In this paper, a robust video ...

Temporal synchronization is a problem that cannot be ignored in most video watermarking application. In this paper, a video watermarking scheme is proposed to resist temporal desynchronization by using shot segmentation and two-dimensional principal component analysis (2DPCA). In this scheme, the to-be-watermarked video is first segmented into different shots. And each shot is analyzed by 2DPCA...
