Watermarking Method Using Line and Diagonal Profile for Text Documents
Yi Bin Ying · Mini-micro Systems · 2005
A watermarking method for text documents was presented using line and diagonal profile. The watermark is embedded into text documents based on its characteristic, and watermark bits embedded can be very large. The watermark is extracted using line diagonal profile without resorting to original unmarked text document. In addition, the text diagonal profile can be used to detect the integrality of text document. Experimental results show that this method is robust with a certain extent to the typical image processing attacks such as cut and noise addition.
