Abstract: Film theft has such a profound impact on a wide range of economy that it is a crime in almost all countries. One major source of the movie piracy is camcorder piracy i.e., movies are recorded by portable devices inside theaters and then sold on internet and grey markets. Different techniques and strategies are explored to overcome the problem and secure the digital cinema content, some are based on spatiotemporal modulation of light, watermarking techniques, maximizing annoyance and temporal effects. This paper deals with a projection technique to avoid piracy in movie theaters. We aim to defeat camcorder piracy by severely degrading the visual quality of the recorded movie while making the interference signals invisible to the audience. Infrared emitters are installed in movie theaters to interfere with the camcorder and create glares in the recorded frames.
