An anonymous reader writes "HP has received a patent on technology that would allow anyone who didn't want their picture taken to remotely instruct cameras to blur their face. While this is being promoted as a privacy measure, does anyone else see the serious rights issues here? What's to prevent this being used by police to block their images when they're beating or otherwise mistreating people? If this tech can be used to blur faces, it can be quite easily adapted to turn cameras off altogether, with deeply troubling implications. And even without these 'what if' scenarios, isn't there an expectation that, if you're in a public area, you're fair game for being photographed?"
