原始语种摘要: Abstract(#br)In this paper a novel image based data security and authentication based, image watermarking scheme that combines the discrete wavelet transform (DWT) and Singular value decomposition (SVD) is proposed. This paper explains a dual watermarking scheme with different algorithm. At first original image is divided into its appropriate levels by using DWT, and convert LL sub-band to its red, green and blue component, and the obtained colour component of image is divided into non-overlapping blocks, final apply SVD on each block to obtained the singular value for watermarking. The second scheme chose HH sub-band of original image and converts its own red, green, blue component, and then apply SVD to each colour component to obtain the singular value for watermarking. We take two...
