Internet users hoping to protect their privacy by using Web anonymizers, false identities and disabled cookies on their computer's Web browser have something new to think about – a patent filed by the National Security Agency (NSA) for technology that will identify the physical location of any Web surfer.
A patent granted last 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 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.
