| Abstract: | Based on the research of the significance of text digital watermarking in trace of secret paper documents, the common text digital watermarking technology is described, and then Brassil classic Row shifting encoded text digital watermarking technology is analyzed. The three parts to improve the labeling strategies of Mark watermarking algorithm are inspection coding, text line spliting and base reference line. The improved method has a greater capacity of the watermark information, more robust and controlled amount of computation. |
