Abstract

We propose a new optically written watermarking technology that uses a one dimensional high frequency pattern to protect the portrait rights of 3-D shaped real objects by preventing the use of images captured illegally with cameras. We conducted experiments using a manikin’s face as a real 3-D object assuming that this technology would be applied to human faces in the future. We utilized the phase difference between two color component patterns, i.e., binary information was expressed if the phase of the high frequency pattern was the same or its opposite. The experimental results demonstrated this technique was robust against the pattern being deformed due to the curved surface of the 3-D shaped object and a high accuracy of 100% in reading out the embedded data was possible by optimizing the conditions under which data were embedded. As a result, we could confirm the technique we propose is feasible.
