Use of physical location and timing delay in fraud detection
View Patent ↗Using timing delays associated with user devices on a network and the demographics of the neighborhood(s) in which the user devices reside to determine whether to generate a fraud alert.
1. A method for alerting of a movement of a user device comprising:
recording a first timing offset for a user device;
obtaining a subsequent timing offset for the user device;
determining whether a difference exists between the first timing offset and the subsequent timing offset;
if a difference exists between the first timing offset and the subsequent timing offset, then, based on a subscriber address associated with a subscriber account associated with the user device, determining a population density characteristic of a premises location within which the user device should be located;
applying a timing offset difference threshold related to the characteristic; and
if the timing offset difference threshold related to the characteristic is exceeded, then performing an alert.
2. The method of claim 1 , wherein the population density characteristic comprises an indication of a multiple dwelling unit (MDU).
3. The method of claim 1 , wherein the population density characteristic comprises an indication of a suburb.
4. The method of claim 1 , wherein the population density characteristic comprises an indication of a rural area.
5. The method of claim 1 , wherein the population density characteristic comprises an indication of large estates.
6. The method of claim 1 , wherein the alert is processed and the movement of the device is recorded for emergency purposes.
7. A method for alerting of a movement of a user device comprising:
recording a first timing offset for a user device;
obtaining a subsequent timing offset for the user device;
determining whether a difference exists between the first timing offset and the subsequent timing offset;
if a difference exists between the first timing offset and the subsequent timing offset, then, based on a density associated with a plurality of other user devices located in an area encompassing the user device, determining a population density characteristic of a premises location within which the user device should be located;
applying a timing offset difference threshold related to the population density characteristic; and
if the timing offset difference threshold related to the population density characteristic is exceeded, then sending an alert.
8. The method of claim 7 , wherein the population density characteristic comprises an indication of a multiple dwelling unit (MDU).
9. The method of claim 7 , wherein the population density characteristic comprises an indication of a suburb.
10. The method of claim 7 , wherein the population density characteristic comprises an indication of a rural area.
11. The method of claim 7 , wherein the population density characteristic comprises an indication of large estates.
12. The method of claim 7 , wherein when the alert is triggered, the movement of the device is recorded for emergency purposes.
13. The method of claim 7 , wherein the density of other user devices located in an area encompassing the user device is estimated based upon a number of addresses associated with the plurality of other user devices that are within a service radius of the address associated with the user device.
