| Abstract: | A one degree orthogonal function of U system is applied to the anti-counterfeit of commercial bills,and a novel digital watermarking method is put forward.By designing an algorithm and analyzing experiment results,it is found that the method is easily realizable and fights attacks like daubing,cutting,compression of JPEG and noise-adding.It is suitable for anticounterfeit and authentication of commercial bills. |
