Drew Conway comes to the rescue with an R package (amusingly called stalkR) that lets you import the data from a named device into an R object for visualization or other analysis. Within that, I included some steps detailing how you can prevent advertisers. If you have more than one iDevice the tool only shows the data from the one you most recently synced, and more importantly it doesn't (directly) give you access to the location data if you want to do more with it. I recently wrote a useful guide on how to use Apple’s new privacy features in iOS 14. Here's why the data for my iPhone looks like when zoomed in on California: ![]() Pete Warden has provided a tool that lets you easily access and map the data. Personally, I'm kind of interested to get access to where I've been over the past year: wherever I go, my iPhone goes. ( Update Apr 27: Apple responds that the locations are those of nearby cell towers and wi-fi hotspots, not the device itself.) Naturally, there's been some controversy over the privacy implications of the data keing kept, but from a data scientist's perspective this represents a rich and interesting data source for analysis. It’s a very fresh way to look at our lives.Earlier this week, data scientists Pete Warden and Alasdair Allen reported that iPhones and cell-enabled iPads keep an internal log of the devices location, which is accessible from the backup that iTunes creates when you sync the device. Intriguing and beautiful patterns emerge as people cross paths. Maria Scileppi has created the Living Brushstroke project (see video below) to capture people’s movements at events, and turn the data into art. I’ve long been a fan of Geoloqi’s opt-in service for recording and sharing your travels, but several other projects in the same area have appeared in my inbox over the last few days. And by that, we dont mean just your current location. Unfortunately, that means that similar information that’s harder to access behind a company’s firewall may not get the same scrutiny, just because it’s harder to show in a way that connects with people. Visualization Of An iPhones Saved Location Data Yes, your iPhone is secretly tracking your location. I think one of the reasons that the iPhone Tracker application has had so much use is that it shows people their own data in an understandable way. It’s built from details that a German politician forced his cell phone provider to share after it was caught storing six months of location data on its subscribers. The Tell-all telephone visualization also makes for thoughtful viewing. ![]() It’s eye-opening what the “law enforcement, government, and corporate examiners” who purchase the system can uncover about your behavior. The iPhoneTracker app, developed by Pete Warden, maps the location data logged by your iPhone for the past year. Using forensics tools like the Lantern program that Alex Levinson helped build, anyone with physical access to the device can construct a picture of the user’s life. What Does Your iPhone Know About You? More Than You Think - Alexis Madrigal has written a fascinating follow-up piece covering the data that professionals can read from your phone. At this point we’re just relieved to get an explanation and a fix, but people can examine their own data and decide for themselves how happy they would be sharing it with strangers. Our conclusions still apply.Īpple doesn’t address our claim that this reveals sensitive information about your travels. The Q&A explains the technical workings behind the log and reassures us that only anonymous data is sent back. It explains why there’s lots of locations that don’t match towers, and also why the accuracy is within a few-hundred meters, since we’ve learned that “micro-cells” in urban areas are clustered closely together. These locations are from a “crowd-sourced database of Wi-Fi hotspot and cell tower data.” This matches the picture that was emerging from research. “The reason the iPhone stores so much data is a bug we uncovered,” Apple notes in the statement.Īpple explains that nearby locations are pulled down from an Apple database and stored on the phone. The fixĪpple has just released a Q&A covering this problem and they will be fixing the issues we spotted with a software update. It’s now been a week since we published the iPhone tracking story, so it seemed a good time to cover what we’ve learned.
