Probe: Many on Facebook don’t use privacy controls

Nearly 13 million U.S. Facebook users do not use, or are not aware of, the site’s privacy controls, according to a Consumer Reports investigation on Facebook and privacy.

As a result, users are potentially exposing personal information beyond their network of Facebook friends.

The report also revealed that a projected 4.8 million people have posted about where they planned to go on a certain day, a potential tip-off to burglars.

Some 4.7 million users have “liked” a Facebook page about health conditions or treatments, details that insurers might use against them.

The CR investigation focused on Facebook as it is the largest social network, with a little more than 900 million users worldwide and more than 150 million users in the United States.

The service makes it easy for people to keep up with friends, family and colleagues; discover great content; and connect to causes.

To deliver this service, Facebook and other social networks collect enormous amounts of information and distribute it widely and quickly.

CR points out that all of this data collection is not without risk.

A projected 7 million households using Facebook said they had trouble last year, ranging from someone using their log-in without permission to being harassed or threatened — up 30 percent from the previous year, according to the Consumer Reports Annual State of the Net survey.

And unless an individual has chosen his privacy settings meticulously, one of his friends who runs an app could grant it access to his information without his knowledge, including information that was set to “friends only” view.

Only 37 percent of users say they have used the site’s privacy tools to customize how much information apps are allowed to see, according to the CR survey.

For its part, Facebook says it takes privacy and safety issues seriously. CEO Mark Zuckerberg has said that the company does privacy access checks tens of billions of times each day and that it would offer users greater access to records of its past Facebook activity.

STAYing PROTECTED

Facebook offers many privacy controls that may not be easy to understand. Below are nine tips from CR that will help users understand and use privacy tools:

Think before typing. Even if a user deletes his or her account (which takes Facebook about a month), some info can remain in Facebook’s computers for up to 90 days.

Regularly check Facebook exposure. Each month, check out how the page looks to others. Review individual privacy settings if necessary.

Protect basic information. Set the audience for profile items, such as town or employer. And users should remember: Sharing info with “friends of friends” could expose them to tens of thousands of people.

Know what cannot be protected. Each user’s name and profile picture are public. To protect your identity, don’t use a photo, or use one that doesn’t show your face.

“UnPublic” the wall. Set the audience for all previous wall posts to just friends.

Turn off Tag Suggest. If users would rather not have Facebook automatically recognize their faces in photos, they could disable that feature in their privacy settings. The information will be deleted.

Block apps and sites that snoop. Unless users intercede, friends can share personal information about them with apps. To block that, use controls to limit the info apps can see.

Keep wall posts from friends. Users don’t have to share every wall post with every friend. They can also keep certain people from viewing specific items in their profile.

When all else fails, deactivate. When a user deactivates his account, Facebook retains profile data, but the account is made temporarily inaccessible. Deleting an account, on the other hand, makes it inaccessible forever.
