The invention relates to anti-falsification paper and a manufacturing method thereof. The anti-falsification paper is applied to customized packing of products. The method comprises the following steps: anti-falsification marks are set according to information of products, wherein the anti-falsification marks have truth-falsification information of the products; multiple anti-falsification marks are printed on transfer films in an unified mode; the multiple anti-falsification on the transfer films are transferred onto copper paper; and the copper paper is used for packing the products. The anti-falsification marks are printed on the transfer films in the unified mode, and are transferred onto the copper paper, so that the jet printing process of the anti-falsification marks onto the copperpaper one by one is simplified, and the manufacturing efficiency of anti-falsification packages is improved. The anti-falsification paper has the information of the products, so that the informationcarrying quantity is high, the package duplication is difficult, and the anti-falsification performance of product packages is improved.
