We propose a novel technique for steganography on 3D meshes so as to resist steganalysis. The majority of existing methods modulate vertex coordinates to embed messages in a non-adaptive way. We take account of complexity of local regions as joint distortion of a triple unit (vertice) and coding method such as Syndrome Trellis Codes (STCs) to adaptively embed messages, which owns stronger security with respect to existing steganalysis. Key to the distortion is a novel formulation of adaptive steganography, which relies on some effective steganalytic features such as variation of vertex normal. We provide quantitative and qualitative comparison of our method with several baselines against steganalytic features LFS64, LFS76 and ensemble classifiers and show that it outperforms the current state of the art. Meanwhile, we proposed an attacking method on steganography proposed by Chao et al. (2009) with a high detection rate.
