In order to protect original data, watermarking is first consideration direction for digital information copyright. In addition, to achieve high quality image, the algorithm maybe cannot run on embedded system because the computation is very complexity. However, almost nowadays algorithms need to build on consumer production because integrator circuit has a huge progress and cheap price. In this paper, the authors propose a novel algorithm which efficient inserts watermarking on digital image and very easy to implement on digital signal processor. In further, they select a general and cheap digital signal processor which is made by analog device company to fit consumer application.
