| Abstract: | This work presents an information hiding technique based on the vertex representation for 3D models. The vertex index of the sorted vertex sequence of a cover model (model without messages) is employed to hide messages sequentially, and to identify the correct arrangement of extracted message units. While embedding messages, a vertex is offset to (j + 1)th element in the output vertex sequence, which is saved as the stego model (model with messages), if the integer value of the message unit is j (namely, convert a bit string into an integer). Some vertices are as message vertices and others as non-message and delimiter vertices to deal with collision which means that more than two vertices are offset to the same element. The hidden information is obtained by arranging all message vertices by the vertex order in the sorted vertex sequence. Experimental results show that the proposed approach achieves high capacity without any distortions, gains efficiency in real time, and is robust against rigid body transformations and uniform scaling. |
