| Outline of Final Research Achievements |
A method for preventing unauthorized copying of information shown on a display is proposed. The proposed method applies our previously proposed method to prevent unauthorized copying of films by using the difference in sensitivity between human beings and devices. A near-infrared ray unit, which has no effect on human vision, is installed on existing displays to enable the prevention of unauthorized copying of information shown on the display. Also described is an effective countermeasure against the use of a camera fitted with a short wavelength pass filter based on IR specular reflection of the filter. Testing using the prototype implementation demonstrated that it can effectively prevent the unauthorized copying of displays by completely corrupting the recorded content.
