Multipurpose Watermarking Based on SWT and SVD

Robust SWT SVD Based Digital Image Watermarking Technique

Due to the advancement in computer technology and readily available tools, it is very easy for the unknown users to produce illegal copies of multimedia data which are floating across the Internet. In order to protect those multimedia data on the Internet many techniques are available including various encryption techniques, steganography techniques, watermarking techniques and information hidi...

Research on Color Watermarking Algorithm Based on RDWT-SVD

In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...

Comparative Study of SWT-SVD and DWT-SVD Digital Image Watermarking Technique

Due to use of the latest computer technology in early days with wide available tools with various advance application, it is very easy for the unknown users to produce illegal copies of multimedia data which are floating across the Internet. To protect multimedia data such as images, videos,etc. on the Internet many techniques are available including various encryption techniques, steganography...
