Previously, applications such as games and online greeting cards which have been very popular on Facebook were required to get permission to access profile information but without specifying any particular data.
Bret Taylor of Facebook said in his blog,"Today, we're taking the next step by providing more transparency and control over the information you share with third-party applications and websites."
"With this new authorization process, when you log into an application with your Facebook account, the application will only be able to access the public parts of your profile by default."
"The majority of people on Facebook actively interact with applications and Facebook-integrated websites every month," Taylor said.
"In order for these applications and websites to provide social and customized experiences, they need to know a little bit about you."
The move to revamp Facebook's privacy setting is to appease critics and privacy activists who complained that the company was not properly safeguarding the users' personal information and also to give users more control over the use of their personal data.
