Rapid development in technology has facilitated easy access to data in various domains. Security has hence become a subject of major concern. The paper brings forth a novel approach to embed a robust visible and invisible watermark into video frames, such that the authenticity of the original signal is maintained. Through Digital watermarking scheme, additional information is embedded in the video signal which protects the video from unauthorized access. This becomes instrumental in copyright owner identification. The use of Discrete Wavelet Transform (DWT) and Standard Deviation plays an important role in making this watermarking scheme resistant to various security breaches.

A Wavelet-Based Digital Watermarking for Video
Computing Research Repository - CORR, 2009
A novel video watermarking system operating in the three dimensional wavelet transform is here presented. Specifically the video sequence is partitioned into spatio temporal units and the single shots are projected onto the 3D wavelet domain. First a grayscale watermark image is decomposed into a series of bitplanes that are preprocessed with a random location matrix. After that the preprocessed bitplanes are adaptively spread spectrum and added in 3D wavelet coefficients of the video shot. Our video watermarking algorithm is robust against the attacks of frame dropping, averaging and swapping. Furthermore, it allows blind retrieval of embedded watermark which does not need the original video and the watermark is perceptually invisible. The algorithm design, evaluation, and experimentation of the proposed scheme are described in this paper.
A new approach for scene-based digital video watermarking using discrete wavelet transforms
International Journal of ADVANCED AND APPLIED SCIENCES
This paper presents a scene based video watermarking technique using discrete wavelet transform in the application of video copyright protection. The proposed technique combines the successive estimation of statistical measure (SESAME) technique with video watermarking. In this proposed technique, first level decomposition using 2D-discrete wavelet transform (DWT) of LL sub-band of the cover video frames is considered for embedding. To reduce the computational time, watermark image is inserted only in the scene change frames. To detect the scene changed frame, successive estimation of the statistical measure and HiBiSLI algorithm based scene change detector is designed, which is the most novel-part of the work. In the case of watermarking, the correlation between successive frames is an ideal measure for identifying scene change. The performance shows overall improvement in the measured value of metrics like mean square error, peak signal to noise ratio, normalized correlation, and structural similarity index and bit error rate for embedding using level 1 decomposition. The proposed system achieves robustness against image processing attacks, geometrical attacks, jpeg compression and different video attacks. Further performance enhancements have achieved by embedding at level-2 decomposition. The empirical result suggests that increasing number of levels can improve the performance of the system. Improvement in the robustness and transparency is calculated in terms of bit error rate, normalized correlation and SSIM. Finally, the results are discussed in light of some recently reported studies and have proven a non-blind, robust and imperceptible watermarking system.

The outgrowth in technological world has massively promoted to information fraud and misappropriation by the ease of multimedia data content regeneration and modification. Consequently, security of digital media is considered among the biggest issues in multimedia services. Watermarking, consisting in hiding a signature known as watermark in a host signal, is one of the potential solutions used purposely for media security and authentication. In this paper, we propose a robust video watermarking scheme using Discrete Wavelet Transform and Singular Value Decomposition. We embed the watermark into the mid frequency sub-bands based on an additive method. The extraction process operates following a blind detection algorithm. Several attacks are applied and different performance metrics are computed to assess the robustness and the imperceptibility of the proposed watermarking. The results reveal that the proposed scheme is robust against different attacks and achieves a good level of imperceptibility.

With the era of rapid technology in multimedia, the copyright protection is very important to preserve an ownership of multimedia data. This paper proposes an image watermarking scheme based on Integer Wavelet Transform (IWT) and Singular Value Decomposition (SVD). The binary watermark is scrambled by Arnold transform before embedding watermark. Embedding locations are determined by using variance pixels. Selected blocks with the lowest variance pixels are transformed by IWT, thus the LL sub-band of 8×8 IWT is computed by using SVD. The orthogonal U matrix component of U3,1 and U4,1 are modified using certain rules by considering the watermark bits and an optimal threshold. This research reveals an optimal threshold value based on the trade-off between robustness and imperceptibility of watermarked image. In order to measure the watermarking performance, the proposed scheme is tested under various attacks. The experimental results indicate that our scheme achieves higher robustness than other scheme under different types of attack. 1. INTRODUCTION With rapid growth of internet technology, copyright and security are the major issues towards multimedia distribution. Digital watermarking technique is an alternative solution to provide multimedia protection. Image watermarking technique embeds the copyright information which maintains the quality of the host image. Image watermarking can be performed in spatial and frequency domains. In spatial domain, the watermark is direcly embedded into the image pixels. This scheme provides low computational cost and it is easy to be implemented [1]. This technique can achieve high imperceptibility of the watermarked image. However, this scheme provides weak robustness against noise attacks and JPEG compression. Image watermarking based on transformed-domain produces a good robustness against several attacks. The transformed-domains such as Discrete Cosine Transform (DCT) [2]-[5], Discrete Wavelet Transform (DWT) [6], [7], Integer Wavelet Transform (IWT) [8] have been widely used in image watermarking schemes. Most of watermarking schemes applied hybrid scheme between SVD and transform domains to improve robustness of the watermarked image. watermarking schemes. Lai [9] presented DCT-SVD watermarking scheme based on human visual characteristics. Lai presented the embedding watermark technique by examining the first column of orthogonal U matrix. Lai's scheme can achieve a good imperceptibility of the watermarked image. However, Lai's scheme provides weak robustness against speckle and Gaussian noises. Makbol et al.

An Efficient Watermarking Method Based on Significant Difference of Wavelet Coefficient Quantization
IEEE Transactions on Multimedia, 2008
This paper describes an attack on the recently proposed 'Watermarking Method Based on Significant Difference of Wavelet Coefficient Quantization' [1]. While the method is shown to be robust against many signal processing operations, security of the watermarking scheme under intentional attack exploiting knowledge of the implementation has been neglected. We demonstrate a straightforward attack which retains the fidelity of the image. The method is therefore not suitable for copyright protection applications. Further, we propose a countermeasure which mitigates the shortcoming.

In this paper, a highly robust watermarking scheme based on Discrete Wavelet Transform (DWT) is proposed. It has the following features. First, unlike conventional proposed watermarking techniques, a watermark is embedded into the lowest frequency components. Second, the Human Visual System (HVS) model is adopted to improve the transparency of the watermarked image. Several experiments are conducted t o demonstrate the robustness property of this watermarking scheme. Furthermore, it is worthwhile to mention that the proposed scheme is resistant to the counterfeiting attack.
