Abstract

In this paper, we propose a reversible steganography scheme for 3D mesh models. The scheme first find a subset of vertices for data embedding, followed by encoding the prediction residues of these vertices and the secret bit string by arithmetic coding method. The mantissa part of these vertices is then substituted by the coded arithmetic real numbers. This scheme embeds the secret information into multiple layers such that it is high confidential and capacity flexible. In this scheme, the maximum distortion on the stego model is controlled by the setting of a real value thus it can be controlled to be imperceptible. Experimental results show the efficiency of this scheme.
