Abstract
Text digital watermarking, which is an important research direction of information hiding, can be used for copyright protection of text document. This paper proposed a text digital watermarking algorithm based on human visual redundancy. As the human eye is not sensitive to the slight change for text color, watermarks were embedded by changing the low-4 of RGB color components of characters. Experiment shows that the proposed method has good invisibility and robustness to resist deletion, modification attack etc. As long as there are N/8.6 consecutive characters left in the document, the watermarks can still be extracted completely using proposed algorithm.
