ow a days Internet is offering a great convenience in transmitting large amount of data in different parts of the world. However, the security and safety of long distance communication remains a matter of concern. Recording, editing and replication of multimedia contents may be the consequence of transmission of such data over the internet. In order to tackle this problem the need of copyright ...

Watermarking describes that hide information in digital media such as images, audio and video. This work mainly focuses on invisible and robust watermark schemes for video sequences. A major requirement for the video watermarking schemes is the possibility of invisible watermarking and decoding with no access to the original signal. Piracy and copyright production is a major area of the in Digi...

In the digital world, due to the ease of creating, publishing and tampering of works, copyright protection became a major issue. This issue is much significant in movie industry which cause millions of dollars loses. With new technologies, almost everybody is able to produce, edit and share videos. Thanks to the Internet the sharing of works also, become a breeze. Hence, there should be a mecha...

Digital Watermarking is a technology used for the copyright protection and authentication of digital application. The commercial activity on the internet and media require protection to enhance security. We proposed a new invisible non-blind video watermarking in Quick Response (QR) code technique. In one video frame we embed text message into QR Code image and further embed logo into QR-Code i...

Recent efforts for watermarking digital video extend the results obtained for still image watermarking. As a result, most of the proposed algorithms rely on a frame-by-frame approach. Such an adaptation leads to unreliable algorithms in terms of security. The goal of this article is to stress the problem of collusion when digital watermarked data is distributed at large scale and especially int...

The main field of this study is digital watermarking of compressed video sequences. The targeted area in the field of digital watermarking is data embedding and indexing, which can be used in applications such as video indexing and retrieval. Having in mind that the content in video databases is mainly compressed and that video retrieval applications

This paper proposes a compressed domain video watermarking scheme for copyright protection. In addition to common requirements of watermarking, the unique features of video watermarking such as preservation of bit-rate, compressed domain embedding/detection, and video attacks are examined. For real-time watermark detection, our method is directly applied in the MPEG2 bitstream. More specificall...

Video watermarking is very important in many areas of activity and especially in multimedia applications. Therefore, security of video stream has recently become a major concern and has attracted more and more attention in both the research and industrial domains. In this perspective, several video watermarking approaches are proposed but, based on our knowledge, there is no method which verifi...

Due to the rapid development of the internet, the usages of multimedia data like audio, image and video become very popular. Transmission of digital contents is an easy task but maintaining the ownership is a difficult one, for this various techniques has been proposed. One of the main techniques to protect the copyright is digital watermarking. The concept of digital watermarking has been deri...

Digital watermarking is used to protect digital content such as images, audio and videos that have been tampered maliciously and with higher accuracy. Digital video watermarking is a new and merging area of research to exploit different ways in order to prohibit illegal replication and exploitation of digital contents. In this paper, to maintain the quality of video and to ensure the ownership ...
