We outline what you need to know to know maintaining your privacy on Facebook.

Facebook is used by more than one billion people worldwide every month. People have taken to Facebook because it makes connecting with others so easy. Its popularity is all about sharing: comments, likes and dislikes, links to websites, articles and videos, personal information, your whereabouts and activities. 

The downside to all this sharing, however, is that it reveals your personal information and your internet browsing habits to the social networking websites you use and, in turn, to advertisers, marketers and possibly criminals who operate online.

Data collection

Facebook, one of the most widely used sites worldwide, probably holds more data on more people around the world than any government, and this vast repository has been created by participants who voluntarily divulge details of their lives. However, as the number of Facebook subscribers has grown, there’s also been an increasing unease about how it uses this information. 

Governments, privacy experts, activists and many users are concerned about how and where this personal information is used, who can access it and how Facebook can be compelled to be responsible with this goldmine of data.

Understanding all the privacy settings for your account can be daunting. What you may not realise is that while you have some say over what your friends and the public can see of your profile, Facebook can accumulate personal user data for other purposes.

Your valuable personal information is used to provide targeted advertising within the Facebook platform, as well as to provide feedback to advertisers on who is clicking on their ads.

Privacy experts argue users’ personal information is the product being sold by Facebook to advertisers. A website called Facecrooks publishes information on scams and privacy issues related to Facebook and other social networking platforms to alert concerned people to the risks. It has a “safety centre” with tips and instructions on privacy and security. 

Some critics say Facebook exploits personal disclosure without providing adequate ways to permanently delete or redress comments, photos or other contributions that users don’t like, aren’t comfortable with or change their mind about.

It puts the onus on users to monitor and update changing privacy settings, they argue, and doesn’t offer adequate privacy protection for users because its real customers are the online behavioural advertising industry and buyers for online advertisers. Critics also say that Facebook doesn’t adequately address the implications and risks that come with encouraging other people to tag photos and identify you.

  • Log out of any sites each time you’re finished and before going to browse elsewhere online.
  • Use browser plug-ins to limit how and where your cyber movements can be tracked.
  • Don’t use third-party social media-sharing buttons on websites, such as news sites that ask for your Twitter, Facebook or other log-in details and that can post on your behalf.
  • Don’t sign up to third-party apps, tools or games that want your personal information and can share on your behalf.
  • Go through each setting on Facebook to protect your identity.
  • Don’t sign in to other social services and websites using your Twitter or Facebook profile as this links these profiles for potentially cross-posting and cross-sharing your movements.
  • Look for privacy policies on websites that state it doesn’t collect your computer’s  internet address.
  • Sign out of Google or Gmail before using Google search or use a search engine, such as Duckduckgo, that doesn’t collect or share your personal data.
  • Go to the Google Dashboard (if you have a Google account) to check what information is collected and alter your privacy settings.

It’s alarming that Facebook is changing our definition of privacy by encouraging people to share in the name of friendship without due consideration of the business built on it. In the US, a privacy bill of rights has been proposed to give users greater control over how their data is used on the internet, and while this may not get up, the issue of online privacy will continue to gain importance. 

Facebook’s data use policy runs to many pages and outlines how your data may be used.

Facebook gathers data about you and how you use apps within Facebook, and has information about web users on external websites with Facebook buttons. 

It installs cookies (browser plug-ins) on your computer and uses pixels (code used on web pages) to measure web page views and provides user data to aggregators – external companies that analyse the data for personalising ads within Facebook. It also monitors users on some external sites.
