Affordable WiFi blocking wallpaper, Metapaper, revealed

If you have a home WiFi network, you are likely afraid that the signal could be picked up or even hacked into from the outside. Until now, the best you could do is change your password every so often and hope for the best. Now MaximumPC.com reports that two groups of French researchers have come up with a way to block WiFi signals from leaking out, and it will involve some redecorating.

The teams from the Institut Polytechnique de Grenoble and the Centre Technique du Papier have created a special wallpaper called Metapaper. It has silver triangle shapes that are coated in a special ink made up of silver particles. WiFi signals should be blocked wherever Metapaper is applied, while still allowing for outside signals such as cellular wireless networks to get through.

The price of this wallpaper is supposed to be reasonable, with the creators saying that it should be about the same price as "a classic wallpaper mid-range." You can even place another wallpaper design on top of the Metapaper without losing its WiFi blocking abilities. The catch is that to obtain full WiFi signal blocking, a user would have to cover pretty much all of a home's walls, roof and floors in order to prevent any signals from leaking out. There's no word on when Metapaper will be released.

Surely if someone was so concerned that they would go to the lengh of putting up this wallpaper then turning off wifi and hardwiring would be a better option.
I just don`t see where this "product" is usable, could anyone enlighten me???

Maybe blocking external signals? Less stray waves = better wifi signal in your house/business. For some it's just not feasible to go hardwired - especially if you have a lot of mobile devices. I don't know about you but I can't hook up an ethernet cable to my phone (yes there's USB tethering, but really??).

Tuned Faraday cage wall paper, well it's not original but glad to see someone is finally trying to fill the niche. It has applications that may go beyond just it's intended purpose, I could see the folks that get headaches and claim related other issues from wifi power meters and related things might gobble this up, as long as it actually is effective and is affordable.

Or just turn on access control and only allow your devices' MAC addresses to connect...

this command can change your wireless card MAC address in linux to any MAC you choose

macchanger -m 00:11:22:33:44:55 wlan0

we can sniff your MAC using tools like airodump, then change our MAC to yours

Well some people claim to have health problems because of wifi this combined with wifi blocking paint that already exists may prove useful to them....

"prove useful" == "money from suckers".

So urr, what about windows?

Windows has wallpapers, but be sure to close the Metro, so the wallpaper is actively blocking the signal!

Sounds good also if you want to block outside WiFi networks to help your own WiFi work better if changing the wireless channel and wireless bandwidth settings (to avoid WiFi overlap) doesn't work for you. I see several networks at my home. Not sure about security, because new future wireless technologies might pass through.

This is dumb. WiFi signals suck with every wall it has to go though. I want a better signial not it completely gone. If your worried about getting hacked then put a password on your WiFi.

There are many tools out there to crack wifi passwords within seconds or capture the handshake and bruteforce it using cloud services.

- WEP can be broken in less than 5 mins
- WPA can be broken, but results vary depending on key length
- WP2 secure but still vunerable to a bruteforce attack like WPA

and incase you thought your fancy new router with WPA2 was safe
- Unless disabled, WPS can be exploited in under 30 mins

and dont bother hiding your SSID, it gets broadcast by the wireless devices that use your wifi, it takes only seconds to detect your "hidden" SSID

Sadly the best way to secure your wifi is for people to believe you don't have wifi

Steganographic principle.

Encrypt, but hide also.

Interesting...
Although I won't deny that my first thought when I read the title of this article was a desktop wallpaper that blocked WiFi xD
