How to Opt Out of Google's Wi-Fi Network Mapping

By - Source: Google | B 61 comments

Don't want your Wi-Fi network mapped by Google? Just add the "_nomap" tag to the SSID of your access point and/or router.

On Monday, Google said that wireless access point and router owners can now option out of having their wireless network included in the Google Location Server. All they need to do is change the wireless network name (or SSID) so that it ends with "_nomap." That means if you're one of the millions who use "linksys" as a network name, it will now need to read "linksys_nomap" to avoid Google's Wi-Fi network mapping.

"As we explored different approaches for opting-out access points from the Google Location Server, we found that a method based on wireless network names provides the right balance of simplicity as well as protection against abuse," said Peter Fleischer, Global Privacy Counsel for Google. "Specifically, this approach helps protect against others opting out your access point without your permission."

The solution might not be reasonable for everyone. Google is asking Wi-Fi network administrators, whether they're public networks or located in the home, to manually change their network's SSID name. The task of actually renaming the SSID isn't a big deal for experienced users, and re-connecting Wi-Fi devices to the re-named network may take a few annoying minutes. But what about those who simply hook up their router and move on to other things? Or those who really have no knowledge of setting the proper security or changing the SSID? Some users don't even broadcast an SSID on purpose.

Thus, the idea of asking everyone to change their network's ID on behalf of Google is simply preposterous, outlandish. "99-percent of the people who will want to do this will have absolutely no idea what [changing the SSID] means," rants MG Siegler. "I mean, [Google's] entire post is a joke, right? Please tell me this is a joke."

Yet it's no joke, and Google is hoping that the "_nomap" tag will be adopted by all location providers, not just Google. "Because other location providers will also be able to observe these opt-outs, we hope that over time the '_nomap' string will be adopted universally," Fleischer said. "This would help benefit all users by providing everyone with a unified opt-out process regardless of location provider."

Google came under fire when it was recently discovered that Google's Street View cars were not only taking photos of neighborhoods, but "mistakenly" collecting street addresses, Wi-Fi router SSIDs, MAC addresses, unencrypted passwords and even email addresses. Google quickly halted the collection of personal data, but continued to pick up the unique MACs, SSIDs and physical addresses of Wi-Fi access points and routers.

But now owners of access points and Wi-Fi routers can remove their devices from Google's Location Server using the "_nomap" SSID tag. Once that's changed, the next time a Wi-Fi enabled device like an Android smartphone or tablet tries to use the network to fix its location, Google's Location Server will take note of the SSID and remove its information... so Google claims.

Changing the SSID is rather simple: just hook up to the network via an Ethernet connection and log onto the router or access point (typically 192.168.1.1 or something similar) via a browser. The wireless network name (SSID) is typically changed under the Wireless section. Just add "_nomap" and hit apply, and the device will reboot using the new name. Now you just need to reconnect your wireless devices to the "New" Wi-Fi network (and delete the old one to avoid confusion).

    Good idea, but if a user has the SSID "linksys," what makes Google think the user has the know-how to be able to change it to "linksys_nomap"?

    IMO, a better option would be to allow users to opt-in. "linksys_mapme" or something.

    Oh cmon
    I have a Wii,PSP 3000,laptop,two desktops and family who all have my SSID set
    Now because of Google I have to go thru the trouble of changing my SSID!!! WTF
    this isnt a five minute thing to do
    this is work
    and I shouldnt have to do it
    how about yes_map if you want to be on the Google wifi map
    make it so if you want this done then you do the change
    if you dont want this done then you do nothing

    this is the whole reason I removed Google Earth and Google Chrome
    they are annoying and intrusive with all their background services
    even now I still have a Google update service run on my main Win7 rig
    that even using msconfig and manage-services I can f-ing get rid of!

    this is ridiculous
    why should I have to take time to opt out of something
    it should be if you want to opt in you have to do something

    Google is lame

    i would have thought an opt in would have been a better idea, _mapme makes alot more sense, generally speaking google is providing exposure for these wifi hotspots, so chances are these folks would actively want to be mapped, plus they will have the technical expertise on hand to handle such task

    I'm sure Google is hoping that the average computer user (novice) doesn't know anything about this and/or doesn't add "_nomap" to their SSID. They've really become intrusive regarding information.

    why the !@#$ would the users be the ones to opt out? can't google stop itself from invading privacy or spy map people's wifi networks?
    oh wait, google is the giant corporation that mines loads of data and stores them for personal gain. users are once again the losers.
    the government should step in and make google to comply with privacy laws like germany and other countries did (afaik).

    Yeah they are counting on people either 1. not knowing how to change their ssid or 2. being too lazy too. Losing my respect Google =/

    Don't broadcast your SSID if you don't want others to see it.

    wintermintI'm sure Google is hoping that the average computer user (novice) doesn't know anything about this and/or doesn't add "_nomap" to their SSID. They've really become intrusive regarding information.

    People that don't know how to do that really don't care about it. Even people that do know how to do that do not care; yes, my SSD might be associated with an approximated location on the map. So, what? Besides giving me a faster update in location-related services that I use, which is an advantage, I do not see a threat in this.
    I am usually pretty sensitive when it comes to personal information, but this is not something that I would consider intrusive. People that could associate me personally to that SSID are people that know me, like my neighbors, and these people already know where I live. AFAIK, if someone passes down the street and uses a location-based service, and he is getting that location based on some data on Google's servers that know where he is because of the nearby SSIDs, that does not mean that individual knows what SSID the servers got the info from, nor can he associate me with a certain SSID. He might not even have WiFi enabled at that time, and even if he did, no matter; my network is encrypted.
    This re-naming SSID business is useless: if you whip out your phone and sniff some SSIDs around, you will be able to see them even after the name change. That does not mean you will be able to log in those networks, unless they're left open. Conversely, if your phone gets the location based on the SSID datamap from the server, you will never know that for sure, it does it in the background.
    The argument with the businesses is even sillier: they are public entities, and could not care less about this whole thing. Certainly, they would hope this will put them "on the map" somehow, but it doesn't.

    The problem isn't the idiots who don't got a clue out how routers and switches are configured but google collecting data at all in the first place. Aren't there laws against this if not there is a need for them now because of criminals who do such things often do so to break into wireless networks to take confidential information for monetary gain. I am not happy that every email on google's servers is scanned and every little piece of information that comes across their slimy little hands is sold to third parties such as advertisement companies and governments for reports detailing just about everyone's personal habits that can be gathered from online searches.

    In short google is screwing everyone. Even if you are not directly using their "services" you are still are effected.

    This i think is a total invasion of Privacy if i wanted people to know i have a Wi-Fi signal coming out of my house I'd tell them myself. If i had a Wi-Fi in my house it would be secured and i should have to change my own SSID just so Google Won't map it you should be able to go to google maps and pick your house and put a pin in it saying this is what i have.......

    Also this is whats next for google....... " Google Street will not use X-rays to see whats in your house making it easier to identify your home from Google Maps"

    How about I do them one better...rather than add the _nomap to the end of my SSID, how about I run fakeAP on my box (with my 1W card) and have Google sort through that mess. If enough of us do it, their data captures will be completely useless.

    am i the only one who things people are far too worried about this?

    airwaves off our property are public, no? streets are public. i can turn down the power of my ap if i don't want the signal extending past the boundaries of my property. i can not broadcast my ssid.

    i honestly can't think of anything malicious that could be done with this information that wouldn't warrant legal action.

    great ... if i change that i need to reconfigure the misuz's laptop / phone / work phone . my laptop / phone and work phone plus my tablet .... not inconvenient at all ... i mean its not like my ssid is not chosen on purpose. This is such a big pile of donkey manure ...

    For this matter, just hide the SSID name. Is not a security feature,just use WPA2 encryption for that, but atleast it will help to stay off-mapping from the bigbro'. And use only on Win 7, and do not automatcally conect to the network, is more clean. Xp or Win2003 server machine will reveal the SSID. ;)  Oh crap, you will have to acces the pouter-acces point settings. Nvm!

    while annoying that they collect all this information, it doesn't mean anything to me. I mean, my house is on a street corner. Anyone can collect the same exact information by turning on their phone and looking at the street sign :D

    If you're broadcasting your SSID, you deserve to have it captured and distrubuted. I think Google is being quite sporting about it, since they clearly have no obligation to offer this option to people.

    moving past the whole "invasion of privacy" deal, i have just one question.

    Why?

    What the hell good will this do to ANYBODY to know where the wifi spots are?

    And even if the answer is "to find somebody else's wireless internet" then don't you need to be on the 'net in the first place to access this?

    Stupid and useless, at least streetview made sense.

    also, to all the "SUPER NERDZ" that are bragging about their unbroadcasted SSID, How about when you're setting up a wireless network for grammy and grandpa and don't want seven calls a day about how to connect to the wireless network.

    yeah, OS'es are supposed to remember the connection, but if they disconnect, remove the connection, get bugged, etc etc, then what?

    Plain and simple this whole operation makes no sense.
