The context based privacy model (CBPM) has proved to be successful in strengthening privacy specifications in social media. It allows users to define their own contexts and specify fine-grained policies. Collective-CBPM learns the user policies from community. Our experiments on a sample collection of Facebook data demonstrated the models feasibility in real time systems. These experiments however, did not capture all of the user scenarios; in this paper we simulate users for all possible user scenarios in a social network. We operationalize the C-CBPM model and study its functional behavior. We conduct experiments on a simulated environment. Our results demonstrate that even the most conservative user never incurs risk greater than 20%. Moreover, the risk diminishes to 0 as the trust increases between donors and adopters. The model poses absolutely no risk to other liberal or semi-liberal users. © 2014 Springer International Publishing Switzerland.
