Google Describes Wi-Fi Sniffing In Pending Patent
theodp writes "After mistakenly saying that it did not collect Wi-Fi payload data, Google had to reverse itself, saying, 'it's now clear that we have been mistakenly collecting samples of payload data from open (i.e. non-password-protected) Wi-Fi networks.' OK, mistakes happen. But, as Seinfeld might ask, then what's the deal with the pending Google patent that describes capturing wireless data packets by operating a device — which 'may be placed in a vehicle' — in a 'sniffer' or 'monitor' mode and analyzing them on a server? Guess belated kudos are owed to the savvy Slashdot commenter who speculated back in January that the patent-pending technology might be useful inside a Google Street View vehicle. Google faces inquiries into its Wi-Fi packet sniffing practices by German and US authorities."

As scary as the poster tries to make this sound, this is how you listen for public access points. This post is a scare-mongering dupe.
Yellow journalism is getting to be awfully common here on Slashdot. For instance this troll of a story which just so happens to be from the same author:

There is no reading comprehension in the world, apparently. This patent is about what Google claims it was trying to do -- recording SSID and MAC information for location purposes. It has nothing to do with the "mistaken" data packets (sent unencrypted over the air). How the submitter connected the two, I don't know. I suspect lack of coffee and excess Google hate.
Put identity in the browser.
The difference here is that they actually intercepted data by mistake. If you use Kismet (probably the best wireless sniffing tool for Linux), you can set it to not save data packets, only beacon packets (which really have all the data that Google needs), but by default, it saves everything, including any data packets it sees (encrypted or unencrypted).
It depends on what you're doing what packets you want. If you're trying to break WEP, you only care about encrypted data packets; if you're just doing innocent wardriving, you only want the beacons.
