Patent 6,947,978, granted this week, describes a process based on latency, or time lag between computers exchanging data, of "numerous" known locations on the Internet to build a "network latency topology map" for all users. Identifying the physical location of an individual user, reports CNET News.com, could then be accomplished by measuring how long it takes to connect to an unknown computer from numerous known machines, and using the latency response to display location on a map.
...The...patent does not describe the intended use of the technology by the agency, noting only general uses like measuring the "effectiveness of advertising across geographic regions"
The patent-holder? NSA.
Time to clean up the acts, boys and girls.
