Reclaim your Privacy on Facebook using a Simple Bookmarklet

20 05 2010

Of all social networking sites, Facebook causes the greatest privacy concerns. Certainly since it has changed its privacy options over time.

In the beginning, Facebook restricted the visibility of a user’s personal information to just their friends and their “network”, but the default privacy settings have become much more permissive, as you can see in the video below.
This short video is based on a visualization made by Matt McKeon and gives only an impression of a work-in-progress
(for up to date info check the original animation at http://mattmckeon.com/facebook-privacy/).

The reason? According Facebook founder Mark Zuckerberg the controversial new default and permanent settings just reflect the way the world has changed, becoming more public and less private (see ReadWriteWeb).

“Default” is the key to the problems. You have to opt out to protect your privacy. However to fully protect your privacy on Facebook, you have to navigate through 50 settings with more than 170 options (see great charts at the NY Times!). Facebook’s privacy policy is longer than the American constitution!!!

Shocked by the results of the ACLU’s Facebook Quiz (see Mashable), I already changed my privacy settings last summer. Doing a simple quiz on Facebook meant everything on your profile (whether you use privacy settings or not), is available to the quiz. Even more worrying, when your friends do a quiz, everything on your profile is made available to the developers as well.

Since the default privacy settings have changed, my settings needed to be adapted again. But where were the leaks in the 170 options?

Luckily there is a very simple bookmarklet Reclaim Privacy that can check and fix your profile in 2 minutes (see Mashable.com) It is very easy.

1. First go to Reclaim Privacy and drag the bookmarklet to your web browser bookmarks bar
(in the example I dragged the bookmarklet into Chrome’s bookmarks (upper arrow)

2. Go to your Facebook privacy settings and then click that bookmark (Scan for Privacy, see arrow) once you are on Facebook.

3. You will see a series of privacy scans that inspect your privacy settings and warn you about settings that might be unexpectedly public.
In my case my friends could still accidentally share my personal information. This is indicated by a red sign: “insecure.

4. So I clicked “prevent friends from sharing your data”, and in seconds this was the result:

5. I tweaked the contact information a bit (caution) by changing my contact settings, but I still would allow everyone to add me as a friend (I still have to approve, don’t I?)

Piece of cake!
