Abstract:
A data structure that includes at least one partition containing non-confidential quasi-identifier microdata and at least one other partition containing confidential microdata is formed. The partitioned confidential microdata is disguised by transforming the confidential microdata to conform to a target distribution. The disguised confidential microdata and the quasi-identifier microdata are combined to generate a disguised data structure. The disguised data structure is used to carry out statistical analysis and to respond to a statistical query is directed to the use of confidential microdata. In this manner, the privacy of the confidential microdata is preserved.
