Detecting device movement through analysis of device environment
Methods, systems, and computer readable media can be operable to facilitate the monitoring and detection of a device relocation. A location fingerprint may be generated for a device, wherein the location fingerprint includes information associated with proximal devices. Proximal devices may be identified based on communications received by the device from the proximal devices, and may include devices that are determined to be near in proximity to the device. A baseline location fingerprint may be generated at an instance when the device is expected to be within a designated premise. Subsequent captures of a location fingerprint of the device may be periodically or conditionally taken, and the subsequent location fingerprints may be compared to the baseline location fingerprint. If a significant difference exists between a subsequent location fingerprint and the baseline location fingerprint, a determination may be made that the device has potentially been relocated away from a designated premise.
