A method is described to prevent video images and videos displayed on screens from being re-shot by digital cameras and camcorders. Conventional methods using digital watermarking for re-shooting prevention embed content IDs into images and videos, and they help to identify the place and time where the actual content was shot. However, these methods do not actually prevent digital content from being re-shot by camcorders. We developed countermeasures to stop re-shooting by exploiting the differences between the sensory characteristics of humans and devices. The countermeasures require no additional functions to use-side devices. It uses infrared light (IR) to corrupt the content recorded by CCD or CMOS devices. In this way, re-shot content will be unusable. To validate the method, we developed a prototype system and implemented it on a 100-inch cinema screen. Experimental evaluations showed that the method effectively prevents re-shooting.
