Abstract

An approach is provided that receives, from a radio frequency identification (RFID) tag included with a device, at least three different charge times. Each of the charge times corresponds to a different RFID reader that separately charges the RFID tag with each of the RFID readers being at a different geographic location. A distance between each of the RFID readers and the RFID tag is approximated based on the respective charge times and these approximate distances are used to identify a geographic position of the RFID tag using trilateration. The geographic position of the RFID tag is then used to determine whether to allow the device wireless access to a computer network.

Claims13

Dependent claims

An information handling system comprising:

one or more processors;
a memory coupled to at least one of the processors;
and
a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions comprising:
receiving, from a radio frequency identification (RFID) tag included with a device, at least three different charge times, each of the charge times corresponding to a different RFID reader, and wherein each of the RFID readers is at a different geographic location;
approximating a distance between each of the RFID readers and the RFID tag based on the respective charge times;
calculating a geographic position of the RFID tag using trilateration based on the approximate distances to each of the three RFID readers at the different geographic locations;
and
determining whether to allow the device wireless access to a computer network based on the geographic position of the RFID tag.
