Information Hiding Theoretic Research Based on Digital Watermark Technology

With rapidly growing interest in ways to hide information, a large number of schemes have been proposed for watermarks and other information in digital pictures, video, audio and other multimedia objects. In an attempt to overcome this problem, watermarking has been suggested in the literature as the most effective means for copyright protection and authentication. The main focus of this thesis is the problem of joint watermarking and compression of images due to bandwidth or storage constraints.
