The team in the Interactive and Intelligent Computing division of the Georgia Tech College of Computing used off-the-shelf equipment (camera-mounted sensors, lighting equipment, a projector and a computer) to scan for, find and neutralize digital cameras. The system works by looking for the reflectivity and shape of the image sensors and saturating them with a thin beam of visible white light. The principal applications are expected to be protecting areas such as government buildings and trade shows against clandestine photography, stopping unauthorized amateur photography of, for example, shopping-mall Santas (really!) and defeating video copying in theaters. The countermeasure: film." Sounds perfect for copyrighted public spaces.
