camera blockers

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.

“We’re at a point right now where the prototype we have developed could lead to products for markets that have a small, critical area to protect,” Abowd said. “Then we’re also looking to do additional research that could increase the protected area for one of our more interesting clients, the motion picture industry.”

Abowd said the small-area product could prevent espionage photography in government buildings, industrial settings or trade shows. It could also be used in business settings — for instance, to stop amateur photography where shopping-mall-Santa pictures are being taken.
