Towards Privacy Preserving
Publishing of Set-valued Data on Hybrid Cloud
Abstract— Towards Privacy Preserving Publishing of Set-valued Data on Hybrid Cloud. Storage as a service has become an important paradigm in cloud computing for its great flexibility and economic savings. However, the development is hampered by data privacy concerns: data owners no longer physically possess the storage of their data. In this work, we study the issue of privacy-preserving set-valued data publishing. Existing data privacy-preserving techniques (such as encryption, suppression, generalization) are not applicable in many real scenes, since they would incur large overhead for data query or high information loss. Motivated by this observation, we present a suite of new techniques that make privacy-aware set-valued data publishing feasible on hybrid cloud. On data publishing phase, we propose a data partition technique, named extended quasi-identifier-partitioning < Final Year Projects 2016 >, which disassociates record terms that participate in identifying combinations.
