Security and Robustness Enhancement of Digital Image Watermarking.

      Аннотация: Copyright protection is a major concern in digital image transmission over public channel. For copyright protection, watermarking technique is extensively used. As watermarking has got considerable attention in the past decades; its security and robustness need to be taken care of. The work reported in this research is concerned with enhancement of security and robustness in the image watermarking.It is hoped that the approaches suggested for the watermarking could be used for enhancing the security and robustness in the image watermarking.
