Online social network (OSN) users upload millions of pieces of content to share with others every day. While a significant portion of this content is benign (and is typically shared with all friends or all OSN users), there are certain pieces of content that are highly privacy sensitive. Sharing such sensitive content raises significant privacy concerns for users, and it becomes important for the user to protect this content from being exposed to the wrong audience. To help with this burden, sites like Facebook allows the user to group friends into specific lists, known as friendlists, and encourages to use these pre-created lists in order to specify access control lists (ACLs) while sharing content. While this approach greatly reduces the burden on the user to specify ACLs, it still forces the user to create and populate the friendlists themselves and, worse, makes the user responsible for maintaining the membership of their friendlists over time. In this project we aim to help users further by showing that we can manage these friendlists automatically using network structure over time.
