摘要：

An information hiding scheme based on skeleton theory and inscribed sphere analysis for 3D models is proposed to improve the robustness and capacity of the existing algorithms. According to the definition of the skeleton, the model is analyzed by the Euclidean inscribed sphere analysis theory with each skeleton point as the center of the sphere. The number of times of minimum inscribed sphere analysis of skeleton points is considered as the modification for secret information. Preprocessing of carriers is unrelated with the number of vertexes, the change of coordinates and topology modification, so visual changes of carriers due to secret information embedding can be minimized. Experimental results show that this scheme is of strong robustness and good imperceptivity. Especially robustness against rotation is up to 100%, robustness against other common attacks is strong, and the capacity is larger.
