Camcorder Piracy – IR Based Antipiracy Screen

Abstract

Privacy protection is of increasing importance in this era of information explosion. One major source of the piracy is camcorder piracy i.e., Information are recorded by portable devices and then sold on internet and grey markets. Different techniques and strategies are explored to overcome the problem and secure the digital content, some are based on spatiotemporal modulation of light, watermarking techniques, maximizing annoyance and temporal effects. In this paper, we take an interesting look on identifying the pirates by exploiting the technology of RFID. The unique information embedded in the RIFD's serves as tracking information to reveal the one responsibility for the piracy. This raises the question that to what extent antipiracy actions have been effective in deterring piracy? This is a challenging issue to explore because of the difficulty to capture user behavior. We tackle this question by embedding infrared led behind the screen through which a layer of IR rays generated aids in defecting piracy. A human viewing a screen containing information sees only the information on the screen and does not see the infrared rays being displayed simultaneously. Video cameras aimed to record a screen containing the information, though it comprises of IR filters they are unable to prevent the IR rays from interfering with recording the information.
