Word Spacing and Character Encoding Based on a Combination of Text Features Digital Watermarking Algorithm

Abstract:

The current structure of fine-tuning the text watermarking algorithm against attack is not strong, poor robustness, this paper proposes a word-based encoding and character spacing feature combines text digital watermarking algorithm. This algorithm in the encoding process, a line of text in a word to the left or right horizontal embedded watermark information, and does not move adjacent words, the position of the decoding process as a reference, in the text character width adjustment embedding watermark information. Experimental results show that the algorithm has good invisibility and robustness.
