Summary
Wireless hackers, beware--this window treatment is meant to keep
Wi-Fi signals in and you out.
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
<

traveling through windows.
The film, called
<
http://www.glasslock.co.uk/products_services.htm>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, claims GlassLock UK, a company that sells the
film in Britain.
"The film is developed by the U.S. National Security Agency," said
John Hall, managing director of GlassLock UK. "The only way you can
get hold of it here is through us."
<

Group), the information assurance arm of the U.K.
<
http://www.gchq.gov.uk/>Government Communications Headquarters, has
backed the product, but the intelligence community is keeping an eye
on who buys it.
"We have to get permission to sell it," said Hall. "We have to tell
<
http://www.mi5.gov.uk/>MI5 who we sell it to. It's no problem unless
they're known terrorists."
GlassLock is demonstrating the product at

exhibition ends Thursday.
