Wi-Fi-shielding sheets

Wireless hackers in the United Kingdom could soon face a new obstacle to stealing information. The British government has endorsed a transparent film that can block Wi-Fi transmissions and other wireless signals from traveling through windows. The film, called SpyGuard, can be laminated or fitted inside windows to prevent remote eavesdroppers from penetrating rooms with infrared or Wi-Fi signals to steal information or access private networks. To stop Wi-Fi signals “leaking” from a room, the walls are also covered with a layer of paint that contains the same metals as the SpyGuard film. The film can even prevent hackers from stealing information from the light flicker emitted from computer monitors and reflected on a window.
