Digital watermarking in the singular vector domain
Many current watermarking algorithms insert data in the spatial or transform domains like the discrete cosine, the discrete Fourier, and the discrete wavelet transforms. In this paper, we present a data-hiding algorithm that exploits the singular value decomposition (SVD) representation of the data. We compute the SVD of the host image and the watermark and embed the watermark in the singular v...
متن کاملDigital watermarking of color images in the singular domain
A watermarking scheme suitable for color images is given. The algorithm is based on the well-known matrix factorization technique of the singular vector decomposition. This is achieved by using the fact that a color image can be broken into the RGB channels. These channels are then treated separately as matrices on which the matrix factorization is applied. These matrices are then used to prese...
متن کاملDigital Watermarking in Wavelet Domain
In this paper we propose a wavelet transform based watermarking method. The wavelet coefficients of the watermark are embedded to the most significant coefficients at the low and high frequency bands of the discrete wavelet transform of an image. A multeresolution nature of wavelet transform can be exploit in the process of detection. Experimental results show that the proposed watermarking met...
متن کاملBlock based Digital Watermarking of Gray Images in the Singular Domain
To secure digital images transmitted through communication networks, we have used a block based digital image watermarking scheme based on singular value decomposition (SVD). Traditional SVD watermarking already exists for embedding watermark on the image as a whole. In the proposed approach, the original image is divided into blocks, and then the watermarks are embedded in the singular vector ...
