GEOSPATIAL LOCATION VERIFICATION

摘要

This invention provides a location verification server and a geospatial database in which is stored identity and geospatial location data pertaining to network elements (for instance GSM towers and base station transceivers (BTS)) and transaction devices (such as POS terminals). When a transaction is initiated on a transaction device, a location verification request is transmitted to the location verification server which is programmed to: communicate with the mobile network of the mobile device associated with the transaction to determine the identities of network elements located in the vicinity of the mobile device; to perform a lookup in the geospatial database to determine the stored geospatial locations of the identified network elements and the originating transaction device; and to compare the locations of the transaction device and network elements to confirm location of the mobile device.
