A New Data Perturbation Method of Reference Control in Statistical Database

Abstract:

Data perturbation is a method of reference control in statistical database. Data modification and data exchange are two methods of data perturbation. Data modification replaces the original data with the sample data sequence after deciding probability distribution function of the original data and generating sample data sequence. Data swapping interchanges attribute values of records. While the algorithm of the former is complex, this paper presents a new method in which the sample sequence generation is skipped. We simply sort the original data, divide them into different groups and exchange attribute values of the same group. Experiments show that the proposed method can effectively simplify the former method and guarantee the safety of the statistical data at the same time.
