In this paper, we present a new scheme for digital steganography of three-dimensional (3-D) triangle meshes. This scheme is robust against translation, rotation, and scaling operations. It is based on a substitutive procedure in the spatial domain. The key idea is to consider a triangle as a two-state geometrical object. We discuss its performance in terms of capacity, complexity, visibility, and security. We validate the use of a principal component analysis (PCA) to make our scheme

We conclude by giving some other solutions, including open steganographic schemes that could be derived from the basic ideas presented here.
