Due to digitization of image data with storage and distributed processing, effortless copying, tampering and distribution of digital data has been made easier. Digital watermarking has emerged as a tool for protecting the image data from copyright infringement. In digital watermarking annewlineimperceptible signal watermark is embedded into the host image, whichnewlineuniquely identifies the ownership. In the process of embedding the watermark,newlineit is required that no perceptual degradation is observed. Additionally it is required that these watermarks should not be removable by unauthorized person and should be robust against intentional and unintentional attacks. Conventional Embedding procedure inevitably brings some permanent distortion to the original Image object. The basic problem observed in suchnewlinesystem are robustness, transparency, |
