Not surprisingly, managing fine-grained access control in software is rather challenging. In particular, if access is not configured carefully, information leakage may happen: Users may infer sensitive information through the data explicitly accessible to them in centralized systems or in the cloud. In this paper we formalize this information-leakage problem, by modeling sensitive information as answers to “secret queries,” and by modeling access-control rules as views. We focus on the scenario where sensitive information can be deterministically derived by adversaries. We review a natural data-exchange based inference model for detecting information leakage, and show its capabilities and limitation. We then introduce and formally study a new inference model, view-verified data exchange, that overcomes the limitation for the query language under consideration.}, journal={BIG DATA ANALYTICS AND KNOWLEDGE DISCOVERY}, author={Alborzi, Farid and Chirkova, Rada and Yu, Ting}, year={2015}, pages={403–415} } @article{fattahi_mahootchi_husseini_keyvanshokooh_alborzi_2015, title={Investigating replenishment policies for centralised and decentralised supply chains using stochastic programming approach}, volume={53}, number={1}, journal={International Journal of Production Research}, author={Fattahi, M. and Mahootchi, M. and Husseini, S.
