3D Object Encryption Through a Disruptive Rotational Symmetry Transformation

The need to secure 3D objects that are exchanged over unsecured channels is unprecedented. In this paper, we propose a simple 3D object encryption scheme. The scheme is based on a rotational symmetry transformation that disrupts the pixel locations. Each 3D object is first sliced into a number of 2D images, then the disruptive transformation is applied on sets of 3 pixels of each 2D image at a time. The proposed scheme is shown to exhibit good security properties, in terms of visual analysis, statistical analysis (MSE, PSNR and SSIM), as well as robustness to brute force attacks.
