| Abstract: | A watermarking technology which uses linear least square (LS) with equality constraint to fuse is proposed in the perspective of information fusion. The fusion is based on the action of the attackers and uses the extracted reference watermarks to estimate the attack which the original watermarks got. It is independent of the idiographic algorithm. The results of experimentation show it is more robust. |
