Abstract: Targetted at demands in law or military fields where digital media do not allow any losses,we present a robust reversible text watermarking scheme.According to 0/1 watermarking sequence and the synonymy substitution evaluation model,the watermark is selectively embedded in the original text.The majority voting rule improves the watermarking robustness and reduces the probability of false positives.The original data can be recovered losslessly from the unmodified watermarked text by users who own the private key and secret parameters.Theoretical analysis and experimental results show that the proposed scheme can improve the robustness and invisibility of watermarking.
