Looks like Bill Gates is firing some shots at Google Glass. A new patent on which Gates is listed as an inventor proposes a technology that would blur computer monitors or alert users when a camera is present.
Granted, cameras are not just in Google Glass, they're in everything these days - cell phones, laptops, they're even on the sides of buildings. But only recently have they become part of a soon-to-be ubiquitous eyewear that could easily record over you shoulder as you, say, check your balance on an ATM or enter sensitive information at your terminal at work. Even the illustration from the patent (seen at the top of the article) pictures an interloper not holding a camera or a cellphone, but wearing conspicuous looking glasses.
Still, as near as I can tell from reading the patent, the camera will be detected by - what else? - a camera. It's like a panopticon arms race that everyone loses because they will be recorded at every angle. Even protecting yourself from surveillance requires a form of surveillance. But it's not as though you aren't already on camera at an ATM, and if this technology will protect you from getting your identity stolen, that would be tremendously useful.
