Location verification

Abstract

A location verifier can be configured to receive a location report of a target mobile device, wherein the location report includes data characterizing a location for the target mobile device. The location verifier can also be configured to receive a list of mobile devices that are within a predefined proximity of the target mobile device. The location verifier can further be configured to interrogate each mobile device in the list of mobile devices for a list of detected devices. Each device in the list of detected devices can be detected through peer-to-peer communications.

What is claimed is: 
     
         1 . A location verifier comprising one or more computers having machine readable instructions, the location verifier being configured to:
 receive a location report of a target mobile device, wherein the location report includes data characterizing a location for the target mobile device;   receive a list of mobile devices that are within a predefined proximity of the target mobile device;   interrogate each mobile device in the list of mobile devices for a list of detected devices, wherein each device in the list of detected devices is detected through radio frequency (RF) peer-to-peer communications; and   determine a likelihood that the location for the target mobile device has been spoofed based on the interrogating.
