A Novel Steganography Approach for 3D Polygonal Meshes Using Surfacelet Transform

Steganography is the science and art ofcommunicating secret data in an appropriate multimedia cover.Three-dimensional (3D) meshes have been used more and morein industrial, medical, and entertainment applications during thelast decades. In This Paper, a high-capacity and very lowdistortion3D-Mesh steganography scheme based on noveldirectional N-dimensional Surfacelet Transform, is proposed.Experimental results show that the cover model distortion is verysmall. This novel approach can provide much higher hidingcapacity and lower distortion than existing approaches intransform domain, while obeying the main Steganographicalfactors on 3-D models.
