| 摘要 |
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. |

1. An apparatus, comprising:
a network module configured to receive a signal identifying an untrusted location, the untrusted location associated with a mobile communication device, the untrusted location having an unknown accuracy; a first data source comparator module implemented in at least one of a processor or a memory, the first data source comparator module configured to compare the untrusted location to a database of known spoofed locations to define a first match when the untrusted location matches a known spoofed location from the database; a second data source comparator module implemented in at least one of a processor or memory, the second data source comparator module configured to compare the untrusted location to a plurality of locations previously received by the network module to define a second match when the untrusted location is statistically overrepresented in the plurality of locations; and a spoofed location detection module operably coupled to the first data source comparator module, the second data source comparator module, and the network module, the spoofed location detection module configured to determine if the untrusted location was determined by the mobile communication device, the spoofed location detection module configured to determine based, at least in part, on at least one of (1) the first match, or (2) the second match. |
