Information Hiding Algorithm for Word Text Document Based on Positioning Key
Liang Liu · Communications technology · 2010
For the mothod that hides the information through setting the character’s character grid attributes could not resist adding or deleting attack, in combination with the font scaling method and by introduction of the positioning key, an improved algorithm is proposed, in which the confidential information is embedded in multiple times and spread evenly into the text by different means. Experimental results show that the improved algorithm is of a fair hiding, could raise its ability in resistance of adding and deleting attack, and enhance the security of secret information and the flexibility of embedding position.
