This paper presents new constructions of families of binary and ternary arrays with low off-peak (periodic) autocorrelation and low cross-correlation for application to video watermarking. The constructions are based on the composition method which uses a shift sequence to cyclically shift a commensurate “column” sequence/array. The shift sequence/array has auto and cross-hit values constrained...

This paper gives the overview of audio and video watermarking. This paper introduces the basic requirements that affect the algorithms for audio and video watermarking which are perceptibility, robustness and security. The attacks which cause manipulations of the audio and video signals are also discussed. The common group of attacks on audio and video data is dynamics, filtering, conversion, c...

this paper investigates the multiplicative spread spectrum watermarking method for the image. the information bit is spreaded into middle-frequency discrete cosine transform (dct) coefficients of each block of an image using a generated pseudo-random sequence. unlike the conventional signal modeling, we suppose that both signal and noise are distributed with laplacian distribution, because the ...

With the recent development in multimedia communication network, data integrity and security of original content is the area of concern. Video is the one of the most popular object which is being shared easily throughout the media. Video watermarking is the current state of research to resolve the video ownership and authenticity related issues. There is a substantial amount of development in s...

Digital Watermarking is a method or technology that hides information in to a digital media. It is a two way process which involves embedding and extraction. Video watermarking technique is somehow similar to image watermarking. This mechanism is used to overcome the problem of security, copyright and content authentication of the digital media. The objective of this scheme is to create a water...

Commercial markets employ digital right management (DRM) systems to protect valuable high-definition (HD) quality videos. DRM system uses watermarking to provide copyright protection and ownership authentication of multimedia contents. We propose a real-time video watermarking scheme for HD video in the uncompressed domain. Especially, our approach is in aspect of practical perspectives to sati...

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

The most important issues in video watermarking are invisibility of the watermark and the resilience of watermarking to attacks. The area of video watermarking has focused primarily on the problem of robustness to geometric attacks, while discounting the problem of more sophisticated attackers. So to improve the robustness of watermark for A new digital watermarking algorithm, for based on LDPC...

Based on previous research work on both digital watermarking and stereo video, a novel scheme for watermarking stereo video is introduced. Firstly, an adaptive watermarking model based on disparity vectors is proposed after analyzing the characteristics of stereo video. Then a new watermarking algorithm is introduced. Adaptive scheme and pre-encoding with low density parity check (LDPC) codes a...

Due to vast usage of internet large amount of exchange has been done over the web. Now a day in the world of internet, many pirated video uploaded on the internet. Video Piracy becomes a serious problem. The mounting interest with reference to digital watermarking throughout the last decade is certainly due to the increase in the need of copyright protection. Video Watermarking plays an importa...
