Description

Storage as a facility has become an significant example in cloud computing for its great suppleness and financial investments. However, the growth is disadvantaged by data privacy concerns: data owners no longer physically possess the storage of their data. In this work, we education the issue of privacy-preserving set-valued data publication. Current data privacy-preserving techniques (such as encryption, suppression, generalization) are not appropriate in numerous real scenes, since they would experience big above for data query or high info loss. Interested by this remark, we current a suite of new methods that make privacy-aware set-valued data magazine possible on hybrid cloud. On data printing phase, we propose a data divider method, named lengthy quasi-identifier-partitioning (EQI-partitioning), which divorces record terms that contribute in classifying mixtures. This way the cloud waiter cannot subordinate with high likelihood a best with rare term mixtures. We prove the confidentiality assurance of our device. On data inquiring phase, we adopt communicating differential privacy strategy to resist privacy openings from arithmetical inquiries. We finally evaluate its presentation using real-life data sets on our cloud test-bed. Our widespread experiments prove the validity and realism of the future arrangement.
