Abstract

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 106 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.

Claims

1. A method of locating a mobile communication device comprising:

in a preparatory process, the step of recording, in a network element data store, data pertaining to a plurality of network elements constituted by communication devices capable of communicating with the mobile device in a device location process, including the identity and geospatial location of each network element; and

in a process of locating the mobile communication device, the steps of;

communicating, from the mobile device, with one or more network elements located in the vicinity of the mobile device;

determining the identity of each such network element; and

looking up, in the network element data store, the geospatial location of each identified network element, thereby to locate the mobile communication device in the vicinity of the network element.

2. The method of claim 1 including the steps of:

in a supplemental preparatory process, recording, in a transaction device data store, data pertaining to a plurality of transaction devices constituted by devices capable of conducting financial transactions, including the identity and geospatial location of each transaction device;

in response to a location verification request originating from a transaction conducted on a transaction device, implementing a location process including the steps of;

determining the identity of the originating transaction device;

looking up, in the transaction device data store, the geospatial location of the originating transaction device;

querying the network to determine the identity of one or more network elements located in the vicinity of the mobile device;

determining the identity of each such network element;

looking up, in the network element data store, the geospatial location of each identified network element; and

comparing the geospatial location of the transaction device, with the geospatial location of the mobile device, as determined in the first location process.

3. The method of claim 2 in which the geospatial location data pertaining to the network elements and the transaction devices are stored in a digital map in a polygon mesh format, the method including the steps of:

determining the location of the originating transaction device with reference to a map polygon;

digitally locating the mobile device in a map polygon with reference to network elements in the vicinity of the mobile device; and

determining the proximity or otherwise of the map polygons of the originating transaction device and the mobile device.

4. A system for locating a mobile communication device, the system comprising:

a network element data store containing data pertaining to a plurality of network elements constituted by communication devices capable of communicating with the mobile device in a device location process, including data pertaining to the identity and the geospatial location of each network element;

means to determine the identity of each such network element; and

programmable logic means programmed to look up, in the data store, the geospatial location of each identified network element thereby to locate the mobile communication device in the vicinity of the network element.

5. The system of claim 4, including a transaction device data store containing data pertaining to a plurality of transaction devices, which data includes data pertaining to the identity and the geospatial location of each transaction device, the system programmable logic means being programmed:

to receive a location verification request originating from a transaction conducted on a transaction device;

on receipt of a location verification request, to determine the identity of the originating transaction device;

to look up, in the transaction device data store, the geospatial location of the originating transaction device; and

to compare the geospatial location of the transaction device with the geospatial location of each identified network element thereby to locate the mobile communication device.

6. The system of claim 4 in which the system programmable logic means is programmed to store the geospatial location data pertaining to the network elements and the transaction devices in a digital map in a polygon mesh format, the programmable logic means being programmed:

to determine the location of an originating transaction device with reference to a map polygon;

digitally to locate the mobile device in a map polygon with reference to network elements in the vicinity of the mobile device; and

to determine the proximity to one another of the map polygons of the originating transaction device and the mobile device.

7. The system of claim 4 including, in the network element data store, data pertaining to supplemental network elements.

8. A method of locating a mobile communication device is substantially as described in this specification with reference to the accompanying drawing.

9. A system for locating a mobile communication device substantially as described in this specification with reference to the accompanying drawings.
