Design and Implementation of a Multiple Watermarking Algorithm for English Texts

For the deficiency of current digital watermarking methods for English texts,the paper proposes a multiple text watermarking method which is based on the characters’ attribute and the words’ content.This method can make a huge contain of the watermarking,on the other hand,the watermarking can be hided effectively.Moreover,it has a strong ability of testing and correcting the watermarking after the demolishing made to the text content or the watermarking by attackers.Attacking experiments have shown that the watermarking has a good ability of robustness.
