Om Malik on yesterday’s big reveal from Facebook:
In fact, Facebook Home should put privacy advocates on alert, for this application erodes any idea of privacy. If you install this, then it is very likely that Facebook is going to be able to track your every move, and every little action. It is a future I wrote about a few days ago, and let me explain using that very same context.
The new Home app/UX/quasi-OS is deeply integrated into the Android environment. It takes an effort to shut it down, because Home’s whole premise is to be always on and be the dashboard to your social world. It wants to be the start button for apps that are on your Android device, which in turn will give Facebook a deep insight on what is popular. And of course, it can build an app that mimics the functionality of that popular, fast-growing mobile app. I have seen it done before, both on other platforms and on Facebook.
But there is a bigger worry. The phone’s GPS can send constant information back to the Facebook servers, telling it your whereabouts at any time.
So if your phone doesn’t move from a single location between the hours of 10 p.m. and 6 a.m. for say a week or so, Facebook can quickly deduce the location of your home. Facebook will be able to pinpoint on a map where your home is, whether you share your personal address with the site or not. It can start to build a bigger and better profile of you on its servers. It can start to correlate all of your relationships, all of the places you shop, all of the restaurants you dine in and other such data. The data from accelerometer inside your phone could tell it if you are walking, running or driving. As Zuckerberg said — unlike the iPhone and iOS, Android allows Facebook to do whatever it wants on the platform, and that means accessing the hardware as well.[Emphasis added]
Android users, as always, beware.
