No Pictures Please: Researchers Develop System to Thwart Unwanted Video and Still Photography
Researchers at the Georgia Institute of Technology have completed a prototype device that can block digital-camera function in a given area. Commercial versions of the technology could be used to stymie unwanted use of video or still cameras.
The prototype device, produced by a team in the Interactive and Intelligent Computing division of the Georgia Tech College of Computing (COC), uses 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-producing sensors used in digital cameras.
