A Two Step Chaos-Based 3D Model Encryption.

Augmented and virtual reality, game designing, medicine, medical engineering, and many other fields all revolve around 3D models. This is because 3D models have superior visual information than digital images. However, in recent years the advancements in digital image encryption are more rapid than in 3D model encryption. As such, more study on 3D model encryption is deemed necessary. In this paper, a new 3D model chaos-based encryption scheme is suggested based on a shuffling process on the vertices and faces that compose the 3D object and a modulation on the vertex coordinates. The effectiveness of the proposed encryption technique is then verified through the distribution of occupied position analysis, peak signal to noise ratio, structural similarity index and correlation coefficients.
