Abstract
Embodiments of the present invention relate to methods and systems for probe data management that facilitate anonymity between a device providing probe data and the probe data. Some embodiments relate to the removal of an association between a device identifier and an assigned probe identifier if no position information is received from the probe device for a predetermined time period, e.g. between 10 and 20 minutes. Other embodiments relate to periodic extraction of probe objects from a data store, such that a probe object is stored for at most a predetermined time period, e.g. 24 hours, and the use of position information from probe objects having the same probe identifier to create a historic journey trace.
