We evaluated our previously proposed technique for protecting copyrights of digital data for 3-D printing. The proposed technique embedded copyright information into not only digital data but also fabricated objects and read it out from the objects to confirm illegal acts such as bootleg products. In this study, copyright information was embedded into low infill density objects by constructing their inside with small high infill density areas, and a near-infrared camera was used for readout. The results obtained from the experiment indicated that the high infill density areas inside low infill density objects could be recognized from near-infrared images. We demonstrated that the proposed technique was applicable to the methods using near-infrared cameras for reading our copyright information embedded inside fabricated objects. |
