Crave privacy? New tech knocks out digital cameras
Researchers at the Georgia Institute of Technology have come up with an inexpensive way to prevent digital cameras and digital video cameras from capturing that secret shot, reports News.com.
"The technology they've devised detects the presence of a digital camera up to 33 feet away and can then shoot a targeted beam of light at the lens, according to Shwetak Patel, a grad student at the university and one of the lead researchers on the project.
That means that someone trying for a surreptitious snapshot of, say, a product prototype or an amorous couple gets something altogether less useful--a blurry picture (or a video) of what looks like a flashlight beam, seen head on.
... The technology is a stab at ameliorating the privacy problems that have arisen with the advent, quick ubiquity and tiny dimensions of digital cameras and camera phones..
