Privacy Protection Method for Multiple Sensitive Attributes Based on Strong Rule

الملخص EN

At present, most studies on data publishing only considered single sensitive attribute, and the works on multiple sensitive attributes are still few.

And almost all the existing studies on multiple sensitive attributes had not taken the inherent relationship between sensitive attributes into account, so that adversary can use the background knowledge about this relationship to attack the privacy of users.

This paper presents an attack model with the association rules between the sensitive attributes and, accordingly, presents a data publication for multiple sensitive attributes.

Through proof and analysis, the new model can prevent adversary from using the background knowledge about association rules to attack privacy, and it is able to get high-quality released information.

At last, this paper verifies the above conclusion with experiments.
