【Abstract】 In this paper,some typical coding methods for information hiding are introduced and their information hiding capacity is analyzed.And a new method of hiding secret information is presented by analyzing the structure of the word text document,zooming characters,coding RGB value of font gray and modifying the RGB value of the character underline in the word text document.The theoretical analysis and experiment show that it can obtain high information hiding capacity.更多还原
