The NSA is Inventive - Just Look at Their Patents

What do a voice identifier, an automated translator, a "tamper-indicating" document tube, and a supersecure manhole cover have in common? They're all technologies for which the secretive National Security Agency (NSA) has been granted patents by the U.S. government, giving the agency the exclusive rights to its inventions.

The four technologies represent a tiny fraction of the more than 270 sleuthy devices, methods, and designs for which the nation's biggest intelligence agency has been granted a patent since 1979, the earliest year for which public figures are available. As the patent holder, the NSA can license the particular technology -- for a fee -- to anyone who wants to use it, so long as the patent hasn't expired.

The NSA's cryptologists and computer scientists have been busy over the years inventing methods of encrypting data, analyzing voice recordings, transferring digital files, and removing distortion from intercepted communications -- all things you'd expect from the world's largest and most sophisticated eavesdropping agency. And the digital spooks have patented gadgets straight out of a James Bond flick, such as tamper-indicating envelopes and finely tuned radio antennas. (more) (The List)
