Security and privacy have emerged as important issues owing to the proliferation of social networking site. Sharing and distribution of relationship-based information on social network sites can have a serious impact on an individual's activity. Moreover, it can exert a negative influence on the overall information society. To solve security and privacy issues of social networking, the authors introduce a policy-based access control model to support access control based on privacy policies. Their system helps to protect users from potential dangers in social network environments. This paper examines the practical applicability of the model by prototyping the system implementation method in the web environment. They also compare their research with other papers on privacy protection for social networks.
