Social networks are emerging as the arteries for information flow on the web. In a previous paper, we introduced a new community-centric approach for information flow control for the social web. This paper introduces two key improvements to the previously introduced mechanisms. The first improvement is the ability to model user heterogeneity with regard to information relaying on the social web. The...
In this paper, we present a novel community-centric confidentiality control mechanism for information flow management on the web. We use a Monte Carlo based algorithm to determine the potential spread of a shared data object and inform the user of risk of information leakage associated with the different sharing decisions she can make in a social network. Using the information provided by our algorithm...
In this paper, for controlling information sharing in online social networks (OSNs) we present a community-centric access control mechanism called myCommunity. We develop heuristic ideas for efficiently computing myCommunities in OSNs and evaluate it using traces from actual OSNs. The experimental results indicate that myCommunity is a feasible idea and simple estimation strategies can be effective...
