Abstract
Some embodiments described herein relate to a method of defining and/or calculating an accuracy score for untrusted location data. The method can include receiving multiple signals including location data. Some or all of the signals may include untrusted location data. When a signal including location data is received, that location data can be stored, for example in a database. The accuracy score can be defined based on the number of entries in the database matching the received location data. If location data is statistically overrepresented in the database, it may be an indication that the location data has been assigned by an untrusted third party, rather than organically determined by the mobile communication device. Accordingly, a relatively low accuracy score indicating that the location data is synthetic can be defined when received location data matches a location that is statistically overrepresented in the database.
