PROBLEM TO BE SOLVED: To provide devices and methods for encryption and decryption of graphical 3d objects.SOLUTION: An asset, which is a graphical 3D object, is protected at a processor of an encryption device that obtains S202 the asset and a proxy including polyhedrons, processes S204 points of the asset to obtain transformed points lying within the polyhedrons of the proxy, and outputs S206 a protected asset including the transformed points. A decryption device includes a processor that decrypts the protected asset by obtaining S208 the transformed points of the protected asset, processes S210 transformed points using a reverse of the transformation to obtain reconstructed points of the asset, and obtains S212 a reconstructed asset using the reconstructed points.SELECTED DRAWING: Figure 2 |
