However, as trending topic extraction algorithms become more sophisticated and report additional information like the characteristics of users that participate in a trend, significant and novel privacy issues arise. We introduce a statistical attack to infer sensitive attributes of Online Social Networks users that utilizes such reported community-aware trending topics. Additionally, we provide an algorithmic methodology that alters an existing community-aware trending topic algorithm so that it can preserve the privacy of the involved users while still reporting topics with a satisfactory level of utility. %G English %Z TC 11 %Z WG 11.3 %2 https://inria.hal.science/hal-01684372/document %2 https://inria.hal.science/hal-01684372/file/453481_1_En_11_Chapter.pdf %L hal-01684372 %U https://inria.hal.science/hal-01684372 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC11 %~ IFIP-WG11-3 %~ IFIP-DBSEC %~ IFIP-LNCS-10359
