Using two factor authentication to locate the user's physical location

Companies often wish to perform market segmentation for their users by location. Other times legal requirements or contracts may limit the provision of data to people

within certain geographic locations.

    The known solutions rely upon the honesty of the user, or the user's device. Certain products only available in set geographic locations map the user's IP address to a location. Many smartphone applications rely upon the device's built in GPS system. However these rely on devices fully under the control of the user. An IP lookup can be countered with a simple proxy or VPN. Using a smartphone's built in GPS can be defeated by customising your smartphone OS so that it will obfuscate your location when desired.

    This article describes a method associated with creating a specified gadget that is locked down, and which contains a GPS chip - it only needs to be accurate to the nearest country. This device will create numeric strings that the user will manually type into a login page, which the application will be able to use to

determine the current location of the user.

    The advantage of this system is that it relies on a small gadget that, unlike a smart phone or a computer, cannot be modified by the user to aid them in circumventing region lockouts.

The following components are required:

A GPS receiver, accurate to the nearest country. Caching is essential.

A list of countries.

A hashing algorithm...
