Signal-blocking wallpaper stops Wi-Fi stealing (and comes in a snowflake pattern!)

By Olivia Smith, Special to CNN

New York (CNN) - Imagine wallpaper that does work for you and for your electronics. Wallpaper that doesn’t only protect your walls, but also protects your health, equipment and data.

Researchers at France’s Institut Polytechnique de Grenoble have worked with the Centre Technique du Papier to develop Wi-Fi-blocking wallpaper. The product, also known as metapaper, claims to selectively filter, reduce or reflect electromagnetic waves.

Metapaper not only protects against intruders stealing Wi-Fi from buildings, but also ensures that signals inside a building are more secure and stronger, the group says. Benefits include data security for companies or people that need dependable Wi-Fi. The wallpaper can also be used to create quieter spaces for places like hospitals and movie theaters.

The high-tech paper does, however, allow FM radio waves and emergency frequencies to pass through. The paper, which has a snowflake pattern on it but can be covered up by traditional wallpaper, is made from renewable resources and is recyclable, according to the Centre Technique du Papier.

Conductive silver ink and metallic patterns on the wallpaper filter around 99% of waves coming from outside, according to the French newspaper Le Monde, which published a story on the topic earlier this year. However, a room cannot be completely safeguarded by the paper - unless you use it to seal off floor, ceilings and windows, of course.

The metapaper also advertises itself as a healthy alternative, since it claims to reduce a person's exposure to electromagnetic waves. Scientists behind the product point to studies that say the overuse of wireless technology could cause harmful heath effects.

The Finnish firm Ahlstrom acquired the rights to the metapaper. Exact cost estimates have not been released. According to the Centre Technique du Papier, the paper is not yet commercially available because it is still in the industrialization phase.

      First, your comment is the same as hudreds before you, and my response to all is the same: Encrytion doesn't stop it from being captured and decrypted! WPA2 is vulnerable to a targeted boomarang attack that does not need a supercomputer to hack, only minutes to hours with a desktop/laptop, depending on how many packets and the length of the key. Second, Just because you hide the SSID doesn't mean that a packet sniffer can't see it. 3rd, MAC addresses can be spoofed.

      All in all, treat encryption like a made-up language, give someone enough time, and they will beable to learn it... babies do it every day.

      Second, it is amazing to me how many people don't understand privacy is not the only benefit. I used to live on a block with 10 multifamily homes. So there were about 10 signals my laptop could see (without using a packet sniffer) and my cantennae picked up on 3-4 more broadcasted SSIDs. Channels 2, 7, and 11 were packed... I ended up using 3 with the most success... just to connect two devices together wirelessly when 1 was hardwired and the other was 15-20 feet away from the router. The significance of blocking incoming RF traffic on 2.4 GHz bands would have been huge, even if it wasn't perfect. To get my PS3 to connect from 50 feet away, I had to go by a wireless network bridge. Also, this doesn't effect most people anymore, but every use Wifi when someone was using a cordless landline phone that happend to use the 2.4 GHz band? If you haven't, know that it effectively jams wifi.

    In a world of ever increasing RF radiation and a growing number of people that are sensitive to EMF, products like this will become commonplace. You can already purchase shielding paint, shielding film and a variety of other products to protect yourself. For those with EHS this is a various serious issue.

    Interesting stuff. Basically a modified faraday cage, that limits the amount of 2.4GHz and 5.2GHz transmissions... but how does it ensure it's success without blocking needed signals... AM/FM/VHF/UHF... Perhaps it only cuts a couple of dBs from the signal... more like a dampener than a wall? Think of it like earplugs for WiFi: your head is the house, the paper is the earplugs, and sound is the WiFi signal... Some sound gets through, you hear what is going on inside better while what is outside is muffled. But only more sublte since the AM/FM et al signals are much stronger than your little WiFi... I just hope you don't plan on relying on your ISP's public WiFi at home.
    Also, in theory, you would be wise to only use it on your exterior walls as to not block the signal from going room to room. The performance boost of the WiFI though is only if you are trying to connect in an area with a lot of signals broadcasting – which end up interfereing with each other.

    To those who say the stuff is dumb and just used WPA2 with a strong password are missing the point. You won't have to worry as much about your wireless encryption because you will know where the boundries are to your network.

      Encryption, doesnt solve everything. In the 2.4 GHz radio range, there are only 3 truly separate frequency channels, the rest overlap. So if you live in an area with lots of WIFI, the overlapping signals will slow everyone down, regardless if they encrypted as there just room for them on the radio bands. By blocking out the outside signals, this paper may help with that problem.

      1) Encryption can be broken, especially when so many vegetables never change the default WEP key on their routers.
      2) Reduction of incoming RF noise improves signal reception inside the building by reducing interference.

      Encryption is a good idea but it isn't sufficient. WEP meets your test but is not secure. WPA TKIP was considered very strong by many until November 2008. Then there's the WPS PIN problem and the PIN can't be changed.

      Excuse me, slow readers? The article does state that the product is aimed largely at businesses, who actually have data worth stealing, and not so much for home users who want to protect their precious pr0n and MP3 stashes.
      When you have a large facility with multiple internal access points, requiring a lot of signal for proper coverage, applying a solution like this to the outer walls will prevent people from sitting in your parking lot and hacking your network. (Yes, this is quite common... when there is actually data worth stealing.)
      Not to mention that yes VA., there are benefits to reducing interference from incoming RF noise.
      Additionally, the article also states that you can cover this up with something a little more to your tastes, like Iron Maiden and Sponge Bob posters.

    I have a 2 story house, with 2 WAPs, one per floor. In my surrounding neighborhood, there are no less than a dozen other WAPs within detection range, so finding a clean signal with no bleed-over from a near-by transmitter can be hellish in the event that I need to replace a WAP or do something radically different with my WAPs.

    For the record, I *do* use WPA2, but unlike most home users, I also use kerberos encryption over the wire internally, and LDAP authentication on all internal resources. I do security audits regularly, and my coworkers have told me that my network is more secure than our employer's network, which is a government agency.

    That said, I'd love to install this 'signal blocking wallpaper' along the inside of my exterior walls in my house to reduce the interference from other wifi nets in my neighborhood. The one problem I could see with that, would simply be a matter of inconvenience to a few guests I have by regularly that use my WiFi from their vehicle out in the street in front of my house (totally authorized; d00d lives in the country and needs a fast link occasionally to update his laptop... I service his systems, so I don't mind). But, outside of them, this could be a big boon to signal dampening where I actually need dampening, and without the expensive cost of building an actual Faraday Cage, which I've considered doing for a few years now.

    For your average Joe Consumer, yes... setting up WPA2 (16chars or better password) should be sufficient. For the paranoid, go ahead and disable SSID broadcasting and maybe even implement MAC ACLs to limit accessibility to a specific list of systems. But for those of us that require advanced signal-transmission screening, this wallpaper could be useful.

    If you need an example of a Faraday Cage, see the movie "Enemy of the State", in which the character played by Gene Hackman has a Faraday Cage in his house (loft), along with enough explosives to trash anyone that would come looking for evidence that he even existed.

    No... the average Joe would have no use for this... but a hacker, or signalling researcher on the other hand could really make use of something like this, because they actually understand the implications of not having it, and the applications in which it can be utilized.

      Sry, I can defeat every protection mechanism mentioned (yes, no bcast (you can illicit beacon packets from a WAP even if bcast is off) and mac acls are trivial to bypass) and that paper will not stop me unless you cover the surface of the entire room or structure – even then you have to consider that I can use a directional antenna and my own power to push the signal through (possible may not be practicle however practicle for some is trivial for others – it is simply a matter of resources). Furthermore, I think your security posture will be better served by following a few basic rules: identify and catagorize your secure accounts and credentials; do not use your most critical credentials over wireless connections at all; implement and use one-time passwords and account numbers; add static entries to your arp caches for your default gateway mac addy (and for other critical systems). Your best bet would be a WAP with IPS capabilities however as you have probably already guessed that can be defeated too. If you are very paranoid or just have good reason then look under the hood of your WAP – most are running embedded Linux and have tcpdump available at the cli – dump all layer2 traffic to a console window and watch the frames fly across your WAP; maybe filter out the legitimate traffic from the dump and you may have a chance of catching a hacker – assuming you are watching or have an alerting system setup (some scripting skills and smtp capabilities and you can whip one together on that WAPs embedded OS fairly quickly)...

      Does the typical wifi "like your unit" process all incoming data on the same channel "frequency" should you be using the same frequency as your neighbors? This would waste bandwidth processing and the wall paper in the case, if no other channel spreading was usable, would apply in this case. Are you a consultant?

      maybe, maybe not. Solar radiation, cel phone towers, CB radio, FM, AM, TV radio, all pass through you every second. Not to mention magnetic fields from all the electricity. I think it's a question of proximity. Electromagnetics follow an inverse-squared rule – the further away you get from the source, you dramatically reduce the influence. Just don't hang out next to your router 24/7 or keep your celphone next to your head at all times and you reduce the risk to nearly insignificant.

        I love the reference to the inverse square rule:
        The source of a signal is directly proportional to the strength of the signal at the source and indirectly proportional to the square of the distance the signal has traveled.

        For a point source the signal power is proportional to 1/r^3, not 1/r^2 i.e. r cubed not r squared.

        Jon: it's the power density that matters so it's the surface area of the sphere that matters, so 1/R^2 is correct.

        The strength of your password is irrelevant – the password is not secure enough to require a brute-force attack it can be ascertain exactly. Take a look at the Fluhrer, Mantin and Shamir attack to get an understanding of this if you are inclined. Would you like me too show you your password/enc key in ASCII or hex? Don't worry my wireless client will accept the password in either format...

      A strong password is nice, but it's not the be all/end all of network security. There are nice handy tools that even casual wardrivers use to crack consumer-grade encryption.
      I repeat myself yet again... this product is being marketed most heavily towards corporate environments, where there is data that is actually worth the effort to steal. Keeping the signal from penetrating the walls of the building is a big advantage in that situation.

The more people on your connection the slower it is pretty soon if people are stealing it from a coffee shop, users will complain or be upset about the slow network and just go elsewhere.

      For home use, you are right, just secure it with the build in methods of your router. No need for wallpaper.

      Put as strong a password as you want on your consumer wifi router and it can still be easily cracked. Both WEP and most routers with WPA can be easily cracked with simple programs and instructions found on YouTube. The extent of knowledge needed to secure consumer wifi networks properly is far beyond what is reasonable to expect from someone who picks up a $60 Linksys router from Best Buy.

      And even if you secure your network from people using it, that doesn't necessarily mean it's secure from people intercepting or snooping the data being transmitted. Plus, this could be very useful for people in dense buildings who run into interference problems from signal bleed.

      As more and more wireless devices take hold, I can imagine this and other Faraday cage-type solutions will become commonplace.

      I had people throwing random passwords for 6 months at my wifi. Everytime they did this, it caused the wifi to shut down, then you would have to re-enter your password to get it to come back on, only to have them try another password with in 15 minutes. Eventually I had to buy about six 50 foot earth net cables, for all the computers, and game machines. After all of this, I will give anything a try...

        Apparently your WiFi name can be seen/known by those around you when searching for connections. You need to first create a new WiFi connection name and then have all your internal computers auto connect to this every time you power them up or log in. Then go into your routers setup and turn OFF the broadcast SSID feature. Now not even your computers will see the WiFi spot when searching for connections but they will know to auto connect to this location even if it isn't broadcasting its name. If you can do this within a span of a few minutes at a time during the day when not many folks are awake (4 AM) you can minimize the exposure time and nobody would be the wiser.

Now if I put up Wi-Fi shielding in my own house, then how am I going to get an optimum signal in the kitchen or living room from my office?

    This is the best news of the day. I live in an apartment complex and we had major attacks on our wifi a little over a year ago. The attacks at certain times of the day were every 15 minutes or less. We were able to narrow it down to a family that was living up above us, but even then, there was nothing we could do about it. Unfortunately after 6 months of this, we were at our wits end and we lost our cookies, we notice a teenage boy was staying there with a girl that was definitely under age big time. (We thought they were brother and sister, until we saw them kissing one day.) We decided to call child protective services, we also found out at the time, they had not paid any rent for three months, but with in a two days of making that call, all attacks on our wifi came to an end, and they moved out a month later. Until you go through some thing like this, you have no clue what it is like. Try watching a movie from Netflix, or just watching a video, or just looking up some thing on the internet, or downloading anything, and then all of sudden you lose the wifi, because someone is throwing passwords at it, trying to break in. I will be the first in line to buy this wallpaper.

        If you use WPA2 + PSK and make the key no less than 32 bytes of gibberish, it would take 2 to 3 lifetimes to crack. In addition you only allow MAC address of your devices and in addition to that you DO NOT advertise you SSID then it is really really really really hard ,dam near impossible to access your network.

    Most rooms in a house have windows, so exactly how is this going to prevent the signals from entering/exiting exactly?

      While you have a window in the interior wall the that separates your apartment from the one next to yours, most people don't.

      I guess stopping your neighbor from stealing your WiFi has its advantages, though I would simply use a stronger pass phrase before going thru the trouble of wallpapering.

      Exactly. It would be nice if routers would come with modes to adjust the signal strength. Or even better, an auto adjustment based on feedback from connected devices. Then one doesn't have to worry about their signal being accessible to someone accross the street....

      But I think what will most likely sell this wallpaper, is the supposed "health" benefits from blocking all those "harmful" EM waves.

    The issue I see is weather it blocks internal signals when you have a router in one room and a device in another room or floor. Seems to me this would then create a situation your trying to avoid? I would suspect that the blocking wallpaper would have to be confined to outside walls so as to not interfere with internal signals. I also heard its price tag was not cheap.

      If you use this only on the exterior walls, you won't have that issue. The signals will bounce around inside the home but not leak out. Since you can wallpaper over this stuff, you can treat specific walls with it and still have a consistent look on the interior walls as well.

    Years ago my wife wallpapered our bedroom with a metallic foil pattern. One stormy night lighting struck the corner of our house where our bedroom was at. Once we recovered from the flash blindness we saw two dime-sized holes blown in opposite walls where the lighting had arced across the bedroom. Also all the places at the wallpaper seams around the room where the foil pattern was close had been peeled back by the lighting strike. We were sleeping in a Faraday Cage and didn't know it. We had the paper removed that week. So be careful.

He just finds the strongest signal in the area, somehow gets the password in a matter of seconds, and he's got free wifi.

      2 told 1 the password for the strongest wifi signal. It was a random jumble of numbers and letters, and since I was sitting next to them and could easily hear everything I tried it, too. And all of the sudden 3 random people were using someones super secure wifi :)

        New laws are cracking down on hacking into secured WiFi networks. These laws even go further to include unsecured WiFi networks.

        I completely disagree with the ruling for unsecured systems, and it is quite possible that part of these laws will be eventually overturned. If the owner can't be bothered to use password protection, then the signal should be treated as a public over the air broadcast, just like terrestrial "free to air" radio and TV.

        However, I absolutely agree that hacking a password protected system should be a felony. It is no different than hacking into cable or satellite TV system to avoid paying for it.
