Facebook launched its widely popular application developer program back in May 2007. As of press time, there were more than 14,000 applications. Some, including most of the popular apps, are made by companies, while a few of the popular apps, and a significant number of the long tail of the less popular applications are made by individual developers.

But a new study suggests there may be a bigger problem with the applications. Many are given access to far more personal data than they need to in order to run, including data on users who never even signed up for the application. Not only does Facebook enable this, but it does little to warn users that it is even happening, and of the risk that a rogue application developer can pose.

Privacy problems for the user

In order to install an application, a Facebook user must first agree to “allow this application to…know who I am and access my information.” Users not willing to permit the application access to all kinds of data from their profile cannot install it onto their Facebook page.

What kind of information does Facebook give the application developer access to? Practically everything. According to the Application Terms of Service,

“Facebook may…provide developers access to…your name, your profile picture, your gender, your birthday, your hometown location…your current location…your political view, your activities, your interests…your relationship status, your dating interests, your relationship interests, your summer plans, your Facebook user network affiliations, your education history, your work history,…copies of photos in your Facebook Site photo albums…a list of user IDs mapped to your Facebook friends.”

The applications don’t actually run on Facebook’s servers, but on servers owned and operated by the application developers. Whenever a Facebook user’s profile is displayed, the application servers contact Facebook, request the user’s private data, process it, and send back whatever content will be displayed to the user. As part of its terms of service, Facebook makes the developers promise to throw away any data they received from Facebook after the application content has been sent back for display to the user.
