As a result of the widespread use of social networking sites, millions of individuals can today easily share personal and confidential information with an incredible amount of possibly unknown other users. This raises the need of giving users more control on the distribution of their resources, which may be accessed by a community far wider than they can expect. Our concern is how to specify and enforce access rules in a social network. The solution proposed in this paper relies on connection characteristics between users, in an extended sense that includes indirect connections. It provides a conditional access to shared resources based on reachability constraints, between the owner and the requester of a resource, specified through access rules. Experimental results show the effectiveness of our approach over a real social network dataset.
