Abstract: To satisfy the requirement of confidential communication,an information hiding scheme based on Mean Shift clustering analysis was proposed for 3D models.Local height is introduced into this scheme to measure the significance,which can be considered as one of the energy characteristics of vertex.Based on this,Mean Shift is used to analyze the vertex into three categories with different energy characteristics.Different information can be hidden into different kinds of vertex by modifying structure characteristic parameters.And the energy characteristics of information and its carrier should be matched as much as possible.Experimental results show that this scheme is of good performance.Especially the anti-analysis ability and the sensitivity to tamper are much better than others and the capacity is also improved greatly.

Key words: Information hiding,Carrier preprocessing of 3D mesh,Energy characteristics of carrier,Mean Shift
