A roundup of today's "Locationgate" news

Last week's news that relatively imprecise cell phone tower location data from iPhones is stored in a file that is backed up onto your computer seems to be gathering a lot of attention. It was even the main topic of discussion on last night's TUAW Talkcast.

"Locationgate" began when two researchers released a Mac app (iPhone Tracker) that not only finds the file on your computer, but also displays that information. The iPhone Tracker plot of my location information (seen above) shows that I seem to spend a lot of time in the Denver area. That's not surprising, since that's where I live.

Bloomberg reported that the South Korean government has contacted Apple for information about location information collection. In South Korea, the collection of GPS coordinates violates privacy laws, so the government wants to know how the information is stored and whether users can choose to turn off the storage of location data. The Korea Communications Commission also wants to know why Apple captures the information and if it is stored on the company's servers.

South Korea isn't the only country in which privacy advocates are up in arms -- French, American, German and Italian regulators also want to know why Apple collects the information. Razorian Fly notes that Apple has already explained why it collects and store this data in a letter to the US Congress last year. Basically, it's done so Apple has its own location services and is not dependent on Google or Skyhook for that information. It's this location data that your iPhone queries when it initially tries to figure out where it is, before the device locks onto the GPS satellite constellation.

Over the weekend, a MacRumors reader allegedly sent an email to Apple CEO Steve Jobs asking why Apple was "tracking him" and threatened to move to an Android-based phone because "they don't track me." Jobs, in one of his typically terse responses, reportedly replied, "Oh yes they do. We don't track anyone. The info circulating around is false." Update: Arnold Kim of MacRumors reports that the email appears to be legitimate and that he's "reasonably confident" that the response came from Jobs.

Essentially, Jobs is correct. Apple isn't actively tracking anyone. Anybody who has watched either CSI or Law & Order for the last 10 years or so can tell you, if law enforcement agencies want to know where you are, they can do so in real time via cell tower triangulation regardless of what kind of cell phone you're using. It doesn't need to be an iPhone -- any phone can be identified as it is passing amidst the grid of towers, and your location can be approximated. The only difference here is that the data is being stored and then synced to your computer after the fact.

The Wall Street Journal whacked the proverbial hornet's nest with a stick this morning when it noted that even when location services are turned off on an iPhone, location data is still stored on the devices. The Journal also reported that the cell tower triangulation method produces rather inaccurate location readings saying that during tests, "the coordinates were not from the exact locations that the phone traveled, and some of them were several miles away."

Locationgate is obviously a hot topic right now, and the best thing that Apple can do to toss this onto the heap of previous teapot tempests is to quickly and publicly disclose exactly how and why it creates the file, what purposes the data is used for, and how other phone manufacturers use location data.

Update: For one of the most logical explanations of the story from an expert in geospatial technology, look no further than Peter Batty's geothought blog.

I can't get this to work... it can't find the "consolidated.db" file. I want to see what it says about me.

It's a Verizon iPhone 4, if that matters, but backups are working again. For the past three years, I've had them disabled, since it would take over an hour to sync my iPod touch.

I just checked my location data.
I was in Greece in September, and there is no record of that.
I was never in Texas, but there are a lot of data locations there.
It has me in Los Angeles, a LOT, and I have only passed through there.
This is really disconcerting, because if something when haywire, and I was accused of something, I have NO faith in the iphone's backing up my alibi(s). Scary to have inaccurate data being collected about oneself.

When I used to have a Palm Pre, using Mobile Hotspot, and I had location enabled on Twitter, it would often put me in Connecticut and New Hampshire, despite being in western New York.

This paragraph from the iPhone Tracker site may (partially) clear up why the data isn't exactly accurate:

"To make it less useful for snoops, the spatial and temporal accuracy of the data has been artificially reduced. You can only animate week-by-week even though the data is timed to the second, and if you zoom in you’ll see the points are constrained to a grid, so your exact location is not revealed. The underlying database has no such constraints, unfortunately."

No, I downloaded the source and took that code out and the data was still inaccurate. Even with the unmodified app, I can see that the grid points near my house don't show much activity, while grid points three miles away (where the cell towers are) show a lot of activity.

Your use of the term "locationgate" strikes me as cheesy. Very cheesy.

Everyone needs to learn the difference between the words "tracking" and "caching."

They also need to learn the distinction between the phrases "cell towers" and "my every movement".

Because the general public is unable to deal with the complexity of technology, much less language, and the fuel that the media adds to the fire by using terms like "locationgate," Apple will have no choice but to...

... "always encrypt the cache file of known cell towers it must save after you turn off the phone's power, in order to keep battery use to a minimum and save the phone from having to constantly contact nearby towers it should already know about.

But you can't say that.

The only thing people will remember is "locationgate" and "tracking my every movement."

Sad, the world we live in, unable to deal with itself. We'll just have to live with it though, eh?

Never let reality or rationality get in the way of a good story.

This doesn't seem like a huge deal to me... if someone has my phone long enough to plug it into a computer and see where I've been, chances are, they've already beaten me up and stolen my phone.

This is actually interesting to see where I've been throughout the US. It even showed my trip to Florida this January. It really doesn't make a difference whether Apple knows my location or not. I just don't care.

I'll be looking for another Hoopla video from Jonathan Mann.

Michigan traffic cops, border officials, and other government reps are already grabbing this specific Apple-created data as part of what they consider a legitimate search. However imprecise the data, it can and will be used against you in a court of law. If a little red dot shows up anywhere near a crime scene, they'll try to use it against you. (Check out flexyourrights.org).

It's not up to Apple to decide what it can or cannot do. They may curate their App Store, but they can't curate what laws apply to them in countries where they operate.

Who are these people that are getting arrested for crimes they didn't commit? I've never known anyone who has been arrested (or even investigated) as part of a crime.

I work as an investigator. For me, access to this information is great. Really reduces the amount of time I have to spend seeking information another way.

However, I'm an investigator for an indigent criminal defense firm. I now can subpoena this file from every police officer, witness, District Attorney, and victim so I can see who they've contacted and if they've left any information such as people they've contacted out of their reports and witness lists.

Of course my client will have access to this information once I obtain it. This means the home addresses, friends, families, churches, etc. . . are now available to someone who otherwise would not have access to this information, like where a cop lives.

It will also lead to the addresses of possible "confidential informants" or other investigations that are going on.

So while you may not be doing anything wrong. And my client, who has only been "accused" of a crime, and more often than you think, poor people are wrongly accused, will have access to this information. For our drug related clients, they'll be able to have cohorts follow snitches, intimidate witnesses, threaten DA's through their families, like approaching one of their children at the child's school.


There are far more serious implications to this information than you realize.

For while you may not be doing anything wrong, because this information isn't accurate, you could be targeted as a possible snitch when in fact the snitch lives in a house a few streets over.

I won't even get into what a bonanza this will be in civil cases.

The phone tracker thing produced wildly inaccurate data for me. It thinks I was in many places I've never been, including Las Vegas (unless the phone went without me). It also pegs San Francisco as the place I've been to the most. I was there for three days last year but if you looked at my data it would say that I lived near Market Street (I spent most of my time around Golden Gate park). It also pegs a lot of travel in cities I never spend any time in, or that I passed through once. It's absolutely worthless for tracking me down.

Anyone grounded in reality will recognize this as the non-issue that it is and go back to more important things.

I think this is because it's not tracking your location, but cellphone and wifi locations so it can work out your location next time your cellphone/wifi chip notices the same stations.

Why is every iPhone issue named with "-gate"? I don't find this funny and meaningful.

Every scandal since the 1974 Watergate break in has been Something-gate. Thank Nixon for the break in, and the Democrats for the name, since they chose to set up shop in the Watergate Hotel. (One of the few privileges of age is a long memory.)

Woops, make that 1972 for the break in. 1974 was when Nixon gave up and resigned.

I question the accuracy of the iPhoneTracker application at rendering this data. The application showed that my phone was very active in states that it had never travelled to. My home city was lit up the most at least, but there were regions in my state that had a large amount of activity that my phone never travelled to. There are also distant states that the phone had been, and in use, which did not register at all.
