Internet that has developed into a good distribution tool for digital data, causing a large increase in digital data sharing, especially in the form of digital images, and causing problems that need attention. One of them is about copyright protection. Watermarking is one technique that aims to protect digital image copyright. In this study, watermarking was carried out using the Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) algorithms in digital images with different file extensions. Transformation of 2 levels of DWT and SVD on the host image and SVD transformation on the watermarked image that inserted in the LL2 sub-band of the host image. Watermarking with the proposed method produces good image quality with PSNR values exceeding 40 dB, SSIM reaching 0.99 and NCC reaching 1. This shows a robust and imperceptible watermarking image.

This paper proposes "Fusion based watermarking with multi level DWT & singular value decomposition" has been implemented. In watermarking scheme, maintaining security and robustness is major hurdle. To address this issue we proposed a novel non blind embedding scheme with Discrete Wavelet transform (DWT) and Singular Value Decomposition (SVD) techniques. This paper details the design of the proposed watermarking scheme and analyses its robustness in the presence of various possible security attacks that involves in degrading the quality of watermark. In the beginning, the cover image color component (especially Red Component) is decomposed into LL, LH, HL, HH with 2 level DWT: these LH & HL coefficients are further divided into 8*8 blocks and each block is compared to build a fused coefficient. Apply SVD on fused coefficient of cover image and watermark image to embed the singular values with sigmod scaling factor. Finally the watermarked image is generated, after applying inverse SVD & 2 level DWT. At receiver side the inverse process has been implemented to extract watermark image. The efficiency and performance of the proposed method is verified with Peak Signal to Noise Ratio (PSNR), Root mean square error (RMSE) and Mean Square error (MSE) and compared with recent works of santhi [12] and harsha [13].

Digital watermarking is a promising and efficient methodology for protecting the copyright of the transmitted multimedia data. Three-dimensional videos (3DVs) are transmitted and stored in the form of compressed information.Thus, there is a great need for compressed 3DV watermarking. This paper presents 2 proposed hybrid watermarking schemes for securing the 3DV transmission. The first watermarking scheme is the homomorphic transform-based singular value decomposition in discrete wavelet transform domain. The second scheme is the 3-level discrete stationary wavelet transform in discrete cosine transform domain. The objective of the 2 proposed hybrid watermarking schemes is to increase the immunity of the watermarked 3DV to attacks and achieve adequate perceptual quality. The performances of the 2 proposed hybrid watermarking schemes are compared with those of the state-of-the-art watermarking schemes. The comparisons depend on both of the subjective visual results and the objective results; the peak signal-to-noise ratios of the watermarked frames and the normalized correlation of the extracted watermark frames. Extensive simulation results on standard 3DV sequences have been conducted in the presence of attacks. The obtained results confirm that the 2 suggested hybrid watermarking schemes are robust in the presence of attacks. They achieve not only very good perceptual quality with appreciated peak signal-to-noise ratio values but also high correlation coefficient values in the presence of attacks. beneficial to ensure copyright. A digital watermark can be embedded either in a compressed video or uncompressed video. 2 Video information are always transported and stored in the form of compressed data. The uncompressed video watermarking schemes can also be used for the compressed-video bit streams; however, they require complete video re-encoding and decoding for the watermark insertion or extraction. In different cases, the complete video stream decoding process is not recommended. So, the compressed video watermarking has recently acquired more attentiveness. Furthermore, the watermark insertion and extraction in compressed data has less computations, because the complete reencoding and decoding of the transmitted stream is not required for embedding and extracting the watermark bits.Recently, several video encoding standards have emerged. The objective of an encoding standard is to achieve high data compression, while maintaining an acceptable quality. The 3D multiview video coding (3D-MVC) is an efficient one of the recent encoding standards used in different applications. The 3D-MVC has received a broad attentiveness, and it is expected to rapidly take place of traditional 2D video coding in numerous applications. 3 In the 3D-MVC system, the original 3D video (3DV) consisting of multiple video streams is taken for the same object by various cameras. Thus, to transport the 3DV over limited resources networks, a highly efficient compression standard must be applied, whilst preserving a high reception quality. ...
