Abstract
Provided are a three-dimensional (3D) data generation device, an analysis server, and a 3D printing method employing a homomorphic encryption scheme. The 3D data generation device includes a memory, a scan module, and a processor connected to the memory and the scan module. The processor generates 3D data of an object scanned through the scan module and encrypts the 3D data in accordance with a homomorphic encryption scheme.
Claims20
A three-dimensional (3D) data generation device, comprising:
- a memory;
- a scan module;
- and
- a processor connected to the memory and the scan module,
- wherein the processor generates 3D data of an object scanned through the scan module and encrypts the 3D data in accordance with a homomorphic encryption scheme.
An analysis server, comprising:
- a server communication module;
- a server memory;
- and
- a server processor connected to the server communication module and the server memory,
- wherein the server processor receives homomorphically encrypted three-dimensional (3D) data from a 3D data generation device through the server communication module, acquires optimized 3D printing control information by performing a homomorphic operation on the homomorphically encrypted 3D data, and generates homomorphically encrypted result data including the optimized 3D printing control information.
A three-dimensional (3D) printing method employing homomorphic encryption, the 3D printing method comprising:
- encrypting, by a 3D data generation device, 3D data generated by scanning an object in accordance with a homomorphic encryption scheme, and transmitting the homomorphically encrypted 3D data to an analysis server;
- performing, by the analysis server, a homomorphic operation on the homomorphically encrypted 3D data to acquire optimized 3D printing control information and transmitting homomorphically encrypted result data including the optimized 3D printing control information to a 3D printing device;
- and
- decrypting, by the 3D printing device, the homomorphically encrypted result data to generate the 3D data and the optimized 3D printing control information and three-dimensionally printing the decrypted 3D data on the basis of the optimized 3D printing control information.
