Implementation of Digital Watermarking Using MATLAB Software

Digital watermarking holds significant promise as one of the keys to protecting proprietary digital content in the coming years. It focuses on embedding information inside a digital object such that the embedded information is in separable bound to the object. The proposed scheme has been implemented on MATLAB, as it is a high level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numerical computation. We wanted to know about how one can embed information in an image such that he can later claim the ownership of that image by extracting back the embedded information. Hence, “copyright protection” of images was our main motivation in starting this project. This paper includes, Implementation of several watermarking algorithms and examines them in terms of how they meet the requirements of different applications and general requirements of watermarking.
