We evaluated our previously proposed technique to protect 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 spherical objects by constructing their inside with small cavities, and thermography was used for readout. An experiment was conducted to examine whether the cavities inside spherical objects could be recognized from thermal images, and the results obtained from the experiment indicated that they were recognized. We demonstrated that the proposed technique was applicable to spherical objects. |
