Limiting privacy breaches in privacy preserving data mining
TL;DR: This paper presents a new formulation of privacy breaches, together with a methodology, "amplification", for limiting them, and instantiate this methodology for the problem of mining association rules, and modify the algorithm from [9] to limit privacy breaches without knowledge of the data distribution.
Proceedings ArticleDOI
Privacy preserving mining of association rules
TL;DR: A class of randomization operators are proposed that are much more effective than uniform randomization in limiting the breaches of privacy breaches and derived formulae for an unbiased support estimator and its variance are derived.
Proceedings ArticleDOI
Information sharing across private databases
TL;DR: This work formalizes the notion of minimal information sharing across private databases, and develops protocols for intersection, equijoin, intersection size, and Equijoin size.
