Facebook has introduced a raft of features aimed at giving users more control over their personal data.
A groups feature will allow people to specify circles of friends with whom they want to share different updates and information.
For the first time, users will also be able to download all the data they have uploaded onto the site.
They will also find it easier to see how individual applications are using personal information, Facebook's chief executive Mark Zuckerberg said.
