‘Researchers develop prototype system to thwart unwanted video and still photography’

A boot stamping on a camera... forever. Yes, I know this is an SLR. But I was using the digital camera to take the photo!

Via Boing Boing, ‘Researchers develop prototype system to thwart unwanted video and still photography’, news from Georgia Tech of a system that scans and finds the CCDs of digital imaging equipment and shines bright light (or a laser) into them in order to flood them with light and prevent usable images being recorded.

“Commercial versions of the technology could be used to stymie unwanted use of video or still cameras. A Georgia Tech camera-neutralizing prototype could soon be used to stop movie piracy and other forms of unwanted digital-camera photography…

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…

…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
