If you live in South Carolina (USA), your car's license plate may joining the Internet soon. The state government is evaluating technology that can be used to make electronic vehicle license plates remotely controlled by the Department of Motor Vehicles. It's strikingly similar to the concept of future license plates shown back in 1989 during the second Back to the Future (video)
film. The idea would be downright scary if it wasn't so cool. Instead of getting your plates stolen, in the future they can be hacked to be advertise your vehicle as stolen and you as a dangerous criminal. That's a new and very different kind of game than the License Plate Game
we know and played as kids.

Researchers at Purdue University have developed a new method to hide information in network communications that they call a temporal (time) cloak. The technical paper, titled A Temporal Cloak at Telecommunication Data Rate
(payment required) describes how waves of light in optical communications can be manipulated to make some data in the communication stream invisible... literally. This explanation of Purdue's invisibility time cloak
compares it to changing the direction of water on a flowing river. The technology isn't ready to be used in any real-world system yet but looks very promising for future wireless network security applications.

Did you know that by measuring how radio signals flow throughout a room, stationary and moving objects can be detected? University researchers recently demonstrated such a proof-of-concept system using Wi-Fi
wireless network equipment. The WiSee
system allows test subjects to trigger home automation
devices, like light switches and consumer electronic gadgets, by detecting their movements and hand gestures.
Wi-Fi was not designed to support such applications, but WiSee illustrates the potential to integrate wireless detection systems like Kinect with computer networks.

If your smartphone discovers nearby Wi-Fi
hotspots, wouldn't it be great if the phone automatically switched from its cellular connection to Wi-Fi, but only when the Wi-Fi link is providing better service, and then automatically changes back to cellular when needed? That's the idea behind real-time traffic steering
. The concept involves adding intelligence into different networks that allows them to share information about their quality of service and enable devices to regularly make decisions about which network they prefer to join. It's not very interesting when your devices are only ever in the presence of one network at a time, but as networks continue proliferating around the world, real-time traffic steering is looking better and better.
