Abstract
Methods, systems and apparatuses, including computer program products, are described for detecting movement of a mobile computing device based upon geospatial data about a property location of the mobile computing device. The mobile computing device generates a baseline geospatial profile including baseline altitude data, baseline pressure data, and a predetermined pressure range. The mobile computing device enters a first operational mode permitting a user to establish a user session on the mobile computing device. The mobile computing device obtains altitude data from a first sensor and pressure data from a second sensor, and generates a geospatial signature based upon the altitude data and the pressure data. The mobile computing device compares the geospatial signature and the baseline geospatial profile, and enters a second operational mode if a difference between one or more corresponding values of the baseline geospatial profile and the geospatial signature exceeds a predetermined threshold.
