| Abstract: | We propose a new algorithms-watermarking ba se d on the Least Squares Method in this paper.The algorithms can be achieved by simulating the solution of linear equations,which transforms watermark embeddi ng and extraction to solve linear equations.By using error-correcting codes, we can increase the robustness of the watermark.It is supported by experiment results that the algorithms is robust to many kinds of attacks. |
