METHOD AND SYSTEM FOR EMBEDDING COVERT DATA IN TEXT DOCUMENT USING CHARACTER ROTATION |
摘要 |
A method and system for embedding data covertly in a text document using character rotation encoding. A character that occurs in first and second occurrences is selected, where the first occurrence of the character is a reference character and the second occurrence of the character as a rotatable character. The rotational orientation of the rotatable character is altered to produce an altered character with a predetermined rotation with respect to the reference character, wherein the rotation represents the embedded covert data. A text document is formatted based on the altered character.
