Optical watermarking technology for protecting portrait rights of three-dimensional shaped real objects using one-dimensional high-frequency patterns

Paper Abstract

We propose a new technology of optical watermarking that uses a one-dimensional high-frequency pattern to protect the portrait rights of three-dimensional (3-D) shaped real objects by preventing the use of images captured illegally with cameras. We conduct experiments using human faces as real 3-D objects assuming that this technology would be applied to human faces to protect their portrait rights. We utilize 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 opposite. The experimental results demonstrate that this technique was robust against the pattern being deformed due to the curved surface of the 3-D shaped object, and the highest degree of accuracy of 100% in reading out the embedded data was possible by optimizing the conditions under which data were embedded. As a result, we can confirm that the technique we propose is feasible.
