Big Brother! According to the New York Times, Copenhagen International Airport is currently testing a new program that monitors passengers based on WiFi data emitted from devices like laptops and smartphones. Airport officials observe travelers from a remote computer, and can tell, within 10 feet of accuracy, where they spend their time -- those arriving and departing are represented by different colored dots. The program, created by Geneva-based SITA, also gives visitors the option to download an iPhone app that provides location-based information, like promotions from nearby restaurants. SITA's VP said the software isn't intrusive, as it follows devices, not individuals, but we're not sure we want anyone to know how long our Android spends in the bathroom -- and you thought those naughty-bit scanners were creepy.
