Automatic Social Group Organization And Privacy Management

With the dramatic increase of users on social network websites, the needs to assist users to manage their large number of contacts as well as providing privacy protection become more and more evident. Unfortunately, limited tools are available to address such needs and reduce users' workload on managing their social relationships. To tackle this issue, we propose an approach to facilitate online social network users to group their contacts into social circles with common interests. Further, we leverage the social group practice to automate the privacy setting process for users who add new contacts or upload new data items. We conducted a user study to evaluate the effectiveness of our solution.
