On the Feasibility of Localising Smart Devices using Air Pressure

Many devices, such as phones and fitness trackers, contain barometers to measure air pressure, allowing the tracking of air pressure over time. While such changes can be used to identify changes in altitude, if a device is stationary, changes could also be used to identity a person’s location in conjunction with meteorological information, which potentially makes pres- sure data sensitive information. We will use the meteorological data to see how effective device localisation can be when matching air pressure profiles to different locations in Ireland
