An Effective Algorithm for Data Privacy in Distributed Environment Using Wavelets

Organizations including census bureau, medical establishments and Insurance companies collect and publish statistical information. Recent researches about the disclosing of individual records shows that £-differetial privacy gurantees higher data utility in the statistical area and provides privacy. Existing methods those capture the data provides little data utility. This paper focuses on privacy preserving data publishing that achieves £-differential privacy through wavelet transform. The experimental studies based on the real and the synthetic datasets.
