My "dumb" phone works just fine for me.Ars Technica reports on a new smartphone privacy threat that bares thinking about: it uses inaudible, ultrasonic sounds to surreptitiously track a person's online behavior across a range of devices, including phones, TVs, tablets, and computers. These sounds, above the range of human hearing, are embedded into TV commercials or are played when a user encounters an ad displayed in a computer browser. While you can't hear the sound, nearby tablets and smartphones can detect it. When they do, browser cookies can now pair a single user to multiple devices and keep track of what TV commercials the person sees, how long the person watches the ads, and whether the person acts on the ads by doing a Web search or buying a product. Of course, they also know the location of all those appliances, too.
