IM-10-02 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Information Management, School of Engineering and Technology Privacy and access control enforcement in Online Social Networks have been of great concern due to the massive use of social network to share information. Online Social networks are like offline social networks that is composed of social behavior being carried out in some context, which makes it even more difficult to formally define and capture privacy. In our work, we identify the similar concept of Privacy as Contextual Integrity by H.Nissenbaum in current social networking scenario(Nissenbaum, 2004). Contextual Integrity is a philosophical concept that captures various aspects related to privacy in a social ambience. We then present the need of categories in OSNs which leads to the finding that not all categories are same and some of them are in conflict in the context of information sharing. For privacy and access control in such a situation we adapt The Chinese Wall Model (Brewer and Nash, 1989) for access control. As a result our model allows sharing of information among various user categories according to the preference of the user. Thesis (M.
