Abstract
An asset, which is a graphical 3D object, is protected at a processor of an encryption device that obtains the asset and a proxy including polyhedrons, processes points of the asset to obtain transformed points lying within the polyhedrons of the proxy, and outputs a protected asset including the transformed points. A decryption device including a processor decrypts the protected asset by obtaining the transformed points of the protected asset, processing transformed points using a reverse of the transformation to obtain reconstructed points of the asset, and obtaining a reconstructed asset using the reconstructed points.
