Zero Based Research on Text Watermark Algorithm

摘要

Previously there was algorithm shortage about making watermark hidden in semantic meaning of text and text formatting, this paper presents a new zero-watermark algorithm based on English text and the algorithm is suitable for Chinese text as well. Firstly, the algorithm determines the textual characteristics through the punctuation mark of texts. Then add the watermark information into the host through coring the information between cryptographic watermark and textual characteristics. The algorithm has a good concealment and strong robustness.
