A Better Approach for Privacy Preserving Data Publishing by Slicing

Mohd Faquroddin | G. Kiran Kumar ^[4]

Abstract: In order to preserve Micro data publishing, several anonymization techniques, such as generalization and bucketization, have been designed. Recent work has shown that generalization loses considerable amount of information, especially for high dimensional data. Bucketization, on the other hand, does not prevent membership disclosure and does not apply for data that do not have a clear separation between quasi-identifying attributes and sensitive attributes. Hence, a novel technique called slicing is presented, which partitions the data both horizontally and vertically. The slicing preserves better data utility than generalization and can be used for membership disclosure protection. Another important advantage of slicing is that it can handle high-dimensional data and also slicing can be used for attribute disclosure protection and develop an efficient algorithm for computing the sliced data that obey the diversity requirement. Several experiments confirm that slicing preserves better utility than generalization and is more effective than bucketization in workloads involving the sensitive attribute and also demonstrate that slicing can be used to prevent membership disclosure.
