%X An information hiding algorithm based on texture mapping of one kind of the document formats of 3D models (OBJ) is proposed in order to improve the robustness. First, 3D model texture maps are transformed into multivariate wavelet form. Second, the singular value decomposition theory is used to extract the multivariate wavelet static coefficients. Last, the secret information and the above static coefficients are merged by multiplication using the three-dimensional Arnold scrambling and texture mapping algorithm, and the merged coefficients are operated by orthographic projection to form the embedding regions. The experiment results indicated that the robustness against some attacks such as wireframe rendering, vertex rendering, patch extrusion, and shearing was improved, and the feasibility of this method was acceptable.
