Text Information Hiding Method Using the Custom Components

摘要

Open Office Xml (OOX) is the Microsoft Office document format type, which has been widely used in the world. It is of great significance to research the OOX document information hiding technology. In this paper, a text information hiding algorithm was proposed. The proposed method used OOX document custom components to hide secret information. Because the custom component was not referenced by the main document, the content and format of the main document have not been modified. In addition, since the information hiding process does not cause any change in the content and semantics of the displayed text in the document, it can resist content-based attacks, semantics-based attacks, and format-based attacks.
