Aim To propose an anti-attack watermarking based on synonym substitution algorithm for Chinese text. Methods According to the high accuracy of WSD algorithm,two indicators are proposed,which are Lexical Similarity and Sense Similarity. For reducing the accuracy rate of WSD,it was argued that it should choose the word,which is low Lexical Similarity and high Senses Similarity,in the synonym substitution. Therefore,the automatical-ly attack will failure. Results The experiment showed the algorithm reduced the accuracy of WSD from 90. 4% to 74. 5%. Conclusion The robustness of watermarking have been improved.
