Online social networking has become one of the most popular activities on the web. Online Social Networks (OSNs), such as Facebook, are increasingly utilized by many people. OSNs allow users to control and customize what personal information is available to other users. These networks allow users to publish details about themselves and to connect to their friends. Some of the information revealed inside these networks is meant to be private. A privacy breach occurs when sensitive information about the user, the information that an individual wants to keep from public, is disclosed to an adversary.
