Claim:
A method of determining the validity of a request for information over a network, the method comprising: receiving a first request from a node of the network, the request associated with first location information and a first time attribute; receiving a second request from the node of the network, the request associated with second location information and a second time attribute; determining a first location of a device from the first location information; determining a second location of the device from the second location information; determining a time difference between the first time attribute and the second time attribute; determining a geographic distance between the first location and the second location; selecting, from a plurality of statistical records of requests each associated with a time difference and a threshold distance, a statistical record of requests based on the time difference; generating a list of valid combinations identifying valid combinations of device information and transmission information; and identifying the second request as a valid request if the geographic distance is less than the threshold distance associated with the selected statistical record; wherein the identifying of the second request as a valid request further includes identifying a geographic location, device information and device transmission information identified in the list of valid combinations.
