US agency to locate surfers by IP address
The US National Security Agency has been granted a patent for technology that can provide the rough physical location of internet users based on their IP address.
Granted last month, the patent application outlines how the geographic location of internet users could be used to "measure the effectiveness of advertising across geographic regions" or flag a password that "could be noted or disabled if not used from or near the appropriate location".
