Scientists Develop Invisibility 'Time Cloak' to Hide Data

[East Coast Pirate]

Researchers have developed an invisibility 'time cloak' which makes it possible to hide data in a continuous stream of light, reported the journal Nature.

The 'cloak' manipulates the speed of light in optical fibers in such a way that it acts as a pocket in time through which data can pass and leave no trace -- that is, the event is entirely obliterated from history.

The 'invisibility cloak' idea is nothing new. In the recent years there has been several announcements of rudimentary invisibility cloak technology that relies on bending light around an object. The temporal cloak idea is built on the same principles, but in this case light waves are pulled apart then compressed to generate time pockets that cloak events.
