Abstract
A mobile device's location and identifier corresponding to the mobile device is received. The mobile device's location is mapped to a plurality of landmarks proximate to the mobile device's location. The proximate landmarks are stored in association with the mobile device's identifier in a geo data store, and the received location data is then discarded. These steps are iterated over time to build up a data store that can be represented as a frequency distribution of the landmarks that surround mobile devices. Such a frequency distribution can be built for each of a plurality of mobile devices, without maintaining records of any mobile device's location.
