Small sum privacy and large sum utility in data publishing.
Journal of Biomedical Informatics(2014)
摘要
•We identify the dilemma allowing inference attacks on privacy preserving publishing.•We show that utility and privacy guarantees can co-exist.•We propose a mechanism, called SPLU-Gen, for offering small count privacy and large count utility.•We introduce a sophisticated reconstruction method for enhanced utility.•We provide a comprehensive set of experiments on two real datasets.
