Abstract:
Watermarking technique is used to solve the issue related to security of data and copyright degradation. This issue has to be determined by keeping a steady prove on the imperceptibility and robustness or strength which incur to be its major goal. In order to achieve these objectives the usage of a mixed (hybrid) transformation is adopted in this paper, the main idea behind applying a hybrid transform is that the cover image is modified in its singular values rather than on the DWT sub-bands, therefore the watermark makes it vulnerable to vivid attacks and maintains its original state. Some simulation results are available to support the methods and relative study.
