Abstract:

A model based on proximity breach for numerical sensitive attributes is proposed.At first,it divides numerical sensitive value into several intervals on the premise of protecting the internal relations between quasi-identifier attributes and numerical sensitive attributes.Secondly,it proposes a (k,ε)-proximity privacy preserving principle to defense proximity privacy.In the end,a maximal neighborhood first algorithm (MNF) is designed to realize the (k,ε)-proximity.The experiment results show that the proposed model can preserve privacy of sensitive data well meanwhile it can also keep a high data utility and protect the internal relations.

Key words: privacy preserving, numerical sensitive attributes, proximity privacy, discretization
