Rainbow: Preventing Mobile-Camera-based Piracy in the Physical World
IEEE International Conference on Computer Communications,
Since the mobile camera is often small in size and easy to conceal, existing anti-piracy solutions are inefficient in defeating mobile-camera-based piracy, thus it remains a serious threat to copyright of Intellectual property. This paper presents Rainbow, a low-cost lighting system which prevents mobile-camera-based piracy attacks on intellectual property in the physical world, eg, art paintings. Through embedding invisible illuminance flickers and chromatic changes into the light, our system can significantly degrade the imaging quality of Rainbow: Preventing Mobile-Camera-based Piracy in the Physical World
