The Wall Street Journal has come forward with a lengthy article about Android and iOS applications, and how they transmit your data to advertisement companies. They assembled a selection of 101 smartphone apps (50 Android apps, 50 iOS apps, and the WSJ's iPhone app -- they haven't seen fit to release an Android version just yet) and found that 56 of them transmit unique identifying data from your smartphone. More specifically -- apps are transmitting the unique device ID, age, location, gender, time spent using the app and other possibly personal identifying data. Yes, it's wallpaper-gate all over again. Let's dissect this a bit, after the break. [WSJ.com]
While Google says app makers bear all the responsibility of how their applications handle the data, they do provide all permissions the application requests access to. We've all seen that when we install apps, but let's be honest, most of us click right past. We shouldn't, but we do. So what happens to all this data that gets sent out?
Mobclix, which handles data for more than 15,000 apps over 25 different ad networks, describes it a bit. Basically, they take your device ID, scramble it so it's no longer humanly readable but can be used in a database, then match it against your location and get Neilsen demographic and spending habits data for your area. With this data, they claim to be able to place you in one of 150 "segments" -- categories like "soccer moms," or "die-hard gamers." This lets the ad company know what ads are likely to interest you. Mobclix does say that the categories are broad enough so that you can't be personally identified, and this is about "tracking people better."
Scary stuff? Maybe. But it's pretty familiar, as it's been happening on the Internet for years. Websites use tracking cookies to do the exact same thing, because there's money to be made in it. As a matter of fact, the Wall Street Journal shouldn't be throwing too many stones in this glass house. Michael Learmonth at Advertising Age found that the WSJ installs on average of 60 tracking files (which the WSJ does admit is true, and classifies their site as a "medium" risk) that followed users to sites like car dealerships, Players club, YouTube, SyFy, and more. And one of the Web's (and smartphone apps) biggest offenders, MySpace, is owned by the WSJ's parent company NewsCorp.
So what does all this really tell us? For one, old media will do and say anything to scare people into pulling back from the "digital age," and are some of the biggest online offenders as well. That and you're never alone on the Internet, which we all should know by now. Pay attention to what an app does, ask yourself why an app needs your gender or age, and use some common sense. It's not the end of the world if Paper Toss knows you drive a Toyota, no matter what people like Rupert Murdoch want you to believe.
