Online Social Networks (OSNs) have attracted a large amount of users to regularly connect, interact and share information with each other for various purposes. Users share a tremendous amount of content with other users in social networks using various services. The recent growth of social network sites such as Twitter, Facebook and MySpace has created many interesting and challenging security and privacy problems. In OSNs, users manage their profile, interact with other users, and self-organize into different communities. Users profiles usually include information such as the user's name, address, birth date, contact information, emails, education, interests, photos, music, videos, blogs and many other attributes.
