Abstract:
We propose a technology that can invisibly embed information into the image of a real object captured with a video camera. It uses illumination light that illuminates the real object. The illumination light invisibly contains information. As the illumination contains information, the image of the object illuminated by such light also contains information. Information in the light is produced by modulating luminance according to the embedded pattern at half-frame frequency. Frame images over a certain period are added up after the sign of the even- or odd-numbered frames is changed. Changes in brightness by modulation in each frame are accumulated over the frames while the object image is removed because the even and odd frames are opposite in sign. This makes it possible to read out the embedded patterns. This paper demonstrates the feasibility of information hiding from our experimental results.
