| Abstract | Existing search-based coverless text steganography algorithms according to the characteristics of the text, do not need to modify the carrier, and have good resistance to detection, but they rely on a large text data set and have a limited hiding capacity. For this reason, this paper proposes a coverless steganography method based on the source XML file organization of the OOXML documents from a new perspective. It analyzes the organization of OOXML documents, and uses the differences of organization to construct the mapping between documents and secret information, so as to realize the coverless information hiding. To achieve the efficiency of information hiding, a compound tree model is designed and introduced to construct the OOXML document category library. Compared with the existing coverless information hiding methods, the text set size that this method relies on is significantly reduced, and the flexibility of the mapping is higher under the similar hiding capacity. |
