Draco-Based Selective Crypto-Compression Method of 3D objects
Abstract
3D objects play an essential part in many differ-ent domains. They are considered to be important assets and therefore need to be secured. Sometimes, certain users may have the right to access only a part of the 3D object, for example the shape of the object, but not the content. Recently, selective encryption schemes have been proposed in order to allow this. 3D objects are often stored on the cloud or need to be rendered in real time, and therefore compression is important. In this paper, we propose a selective crypto-compression method for 3D objects. This is based on the Draco compression method, which was developed by Google for 3D objects. Our method is format compliant, and to the best of our knowledge, we are the first to propose a selective cry to-compression method for 3D objects.
