Abstract
A 3D object is protected by a first device that receives the 3D object, generates translation vectors that are added to the points of the 3D object to obtain a protected 3D object, and outputs the protected 3D object. The protected 3D object is unprotected by a second device by receiving the protected 3D object, generating translation vectors that are subtracted from the points of the protected 3D object to obtain an unprotected 3D object, and outputting the unprotected 3D object. Also provided are the first device, the second device and computer readable storage media.
