Edit your Facebook profile to secure your data
To edit your profile and privacy settings, log in to your Facebook account, then use the Edit option next to each entry to remove some or all of your date of birth entry. Further down the page you can clear entries relating to your email address, employer's address and phone number as well your mobile phone number.
Alternatively, Facebook has now made it easier to control who can and can't view information about you. Click the Privacy option at the top of the screen and then alter the Profile and Search settings to restrict who can and can't find you. Lower down this page are options governing what others are able to do having found you online via your Facebook profile.
Another important change is to the Photos and Videos pages. Click on Profile (from within privacy) and alter the photo tagging and video tagging dropdown menu options from All my friends and networks to either Only my friends or even Only me. Oddly, there is no option under Contact Information, further down this page, to completely hide your IM (instant messaging) screen name, mobile or landline phone number, address or website. You can, however, keep your email address to yourself here.
Click on the Preferences option by the News Feed list and you can then select whether Everyone can see the applications you've installed and recently used.
Facebook has rapidly become an online means of expression for the social networking site's millions of fans, with videos and photos being posted, users sharing likes and dislikes about music, books, films and pet peeves, as well as voting in polls. This also makes it both a voyeur's and a marketing man's dream, allowing all but untrammelled access to the tastes and whims of whole swathes of the populace.
