Content-based access control in an online community

This paper demonstrates how semantic web can provide a solution for controlling access to contents around a community. The main intention of online communities is enabling a platform for users to share information with each other. But there may be some information to which access must be restricted, such as the personal information of a user in the National ID Network. Traditional OSNs or other online communities provide very few or no controlling access to these information semantically. In this paper we have proposed a semantic approach to enhance the access control in any online community depending on the sensitivity of information content. We also mention some major challenges in access control paradigm and show how our model can meet them.
