UIDs are uniquely identifying numbers assigned to every Facebook user that can be used to identify a user’s real name and any publicly available Facebook profile information. Facebook’s developer policies forbid applications to share Facebook user data, including UIDs, with third parties.
What the Congressmen Want
Where’s the breach?
Unlike previous Facebook privacy problems, such as the Instant Personalization flap and Facebook’s loosening of privacy controls, there is some debate about whether leaking Facebook user names is a serious privacy concern.
Blogger, author and professor of journalism Jeff Jarvis said via Twitter that learning that someone is using Facebook is no different than finding someone’s name in the phone book. Forbes writer Kashmir Hill said, “using “breach” to describe this strikes me as overwrought. The applications reveal your name, that you are on Facebook, and possibly which application(s) you’ve downloaded. Is that something that we should be freaking out about?”
In a blog post addressing the issue Facebook said, “Press reports have exaggerated the implications of sharing a UID. Knowledge of a UID does not enable anyone to access private user information without explicit user consent.” The social network promised to do better stating that Facebook is “committed to ensuring that even the inadvertent passing of UIDs is prevented and all applications are in compliance with our policy.”
The real question here may not be the seriousness of this specific privacy breach, but whether Facebook needs to do a better job of policing how its partners are treating, storing and transmitting Facebook user data.
