Paper Abstract

In 3D steganography and watermarking, the synchronization of the hidden data is a major problem. We need to know where the message is embedded in order to extract the correct information. Various algorithms have been proposed for the last couple of years and we focused on a method based on Euclidean minimum spanning tree (EMST) for the mesh vertices. In this paper we analyze the sensitivity of the EMST structure in order to propose a new method more robust. We present a new theoretical analysis and we propose to visualize the robustness of the EMST. Moreover, we can apply this analysis to various applications that can be useful in 3D steganography such fragile area detection and prediction of the 3D object robustness during transmission on a noisy channel.
