Share Your iPhone Location Data Like You Mean It 94

An anonymous reader writes "The crazy guys over at crowdflow.net are begging you for the location data that your iPhone collected without you being aware of it. All your data will be anonymized, and the whole combined data set of all donations will be shared under an OpenDataCommons license. Those people are data and visualization geeks and create beautiful visualizations like this from the data. They previously did a visualization of data retention caused by the German 'Vorratsdatenspeicherung.' Please consider donating your location data. ...and be fast, too, since the upcoming iOS software update (see Apple press release) will prevent further evaluation of the collected data."

      From what i read in the previous slashdot discussion (and from what they write on their webpage) they only want the "base station log", so they wouldn't be able to correlate the data to anyone in particular (unless you are somehow verifiably the only user of a cell tower at a certain point in time.)

        Apple collected the information on their iDevice, and Apple is evil - so everyone rose up in hysteria when the news about this file came out.

      Depends on where you live. I have at least a dozen APs in my list here at home, at least two of them I know to be in the same building, just on different floors. Good luck pinpointing where exactly I live, even if you could fetch out my data set.

      If you're interested in me, there are a lot of easier ways to get my address.

      Really, I dig privacy and all that, but people do get freaked out too easily. Sure I have something to hide, everyone does. But the something is usually what I do, and not where I do it.

      And quite frankly, if you're upset about this data collection (on the device!), but you check in with FourSquare whenever you are anywhere at all, you're messed up.

      Reading someone's Twitter or Facebook postings would probably reveal more about them then checking out their location data. For the average american, I guess a visit to the local whorehouse is the worst that location data would reveal. Sure you don't want that to be public, but the end of the world it is not. Well, maybe the end of your marriage. Then again, if you do stuff that you positively don't want to be discovered, one of the things you do is turn off your mobile phone. That's not news. A guy working closely with the german equivalent of the secret service said 10 years ago that he turns off his mobile phone and takes out the battery routinely whenever he doesn't use it.

      Nothing here is new, except for the specifics of the individual event.

      • Really, I dig privacy and all that, but people do get freaked out too easily.

        Perhaps it's because very few people are experts in data mining; and when you look at the conglomerate of data that is collected about you from various sources, to tell what is "safe" to release and what isn't, you really need to be. So it's best to opt out of tracking even when it is apparently anonymous/harmless/unimportant information, if you want to preserve your privacy.

        • by Tom ( 822 )

          No, I think it is because few people are experts in anything. They have a rough idea that they treasure their privacy, but don't even know what exactly that is.

          I don't blame them, because you are being assaulted from all sides with conflicting messages. The one side tells you that you need to be paranoid about your privacy and the other side tells you "if you have nothing to hide..." - and very few people manage to get their bearings there.

      That doesn't make sense. Either you trust them or you don't. Apple, or any other company, would never anonymize data that they collected, and then run some complicated algorithm to de-anonymize the data again; they would just keep one version that is not anonymized and another version to show everyone that is all anonymized. And you would never find out. _If_ they were lying to you.

The next update will cut the log retention time to a week and not back it up on the host computer (so it will be less accurate for awhile if you restore from backup, but the data can't be compromised via the backup.)

        Apple do the exact same thing. Unless they've changed their Privacy Policy [apple.com] recently. Hold on, I'll check.

        Nope. No change since June 2010, according to the page.

        We may collect information such as occupation, language, zip code, area code, unique device identifier, location, and the time zone where an Apple product is used so that we can better understand customer behavior and improve our products, services, and advertising.

        Keep in mind that's under the section describing the "anonymous" user info they collect. Well, they call it "non-personal information" and explain that it can't be used to identify you, specifically.

        Just the device you use, through that "unique device identifier" they collect.

        Also notice that they don't "use" that information, they "collect" it. Meaning that it's saved.

And only things Apple doesn't know about already would be sent - so let's say once a month when you stumbled on a new WiFi router, Apple would send a rough location of that (accurate to within 1/2 mile or so) and with no other data, including your cell phone ID or name or anything.
