Privacy Preservation Models for the Independent Data Release of High-Dimensional Datasets

Abstract

A major challenge is when datasets are released to utilize in the outside scope of data-collecting organizations, it is how to balance data utilities and data privacies. To achieve this aim in data collection (datasets), there are several privacy preservation models that have been proposed such as k-Anonymity and l-Diversity. Unfortunately, these privacy preservation models can be sufficient to address privacy violation issues in datasets that do not have high-dimensional attributes. For this reason, a privacy preservation model, LKC-Privacy, can address privacy violation issues in high-dimensional datasets to be proposed. With this privacy preservation model, datasets cannot have any concern of privacy violation issues when all L-size distinct quasi-identifier values are distorted (suppressed or generalized) to be at least K indistinguishable tuples. Moreover, every protected sensitive value relates to each group of indistinguishable quasi-identifier values, it must have the confidence of re-identifications to be at most C. Although LKC-Privacy is more efficient and effective than k-Anonymity and l-Diversity, it is generally efficient and effective to address privacy violation issues in location-based datasets. Moreover, we see that datasets satisfy LKC-Privacy constraints, they still have privacy violation issues from using data comparison attacks and they further have data utility issues that must be addressed. Therefore, a new privacy preservation model can address privacy violation issues in high-dimensional datasets such that its satiable released datasets do not have any concern of privacy violation issues from using data comparison attacks and are highly efficient and effective in data maintenance to be proposed in this work. Furthermore, we show that the proposed model is more efficient and effective by using extensive experiments.

Aggregate Query Frameworks for Preserving Privacy Data in Big Data Analytics

“…For this reason, a challenge of data utilization is when datasets are utilized in big data analytics or shared with the outside scope of data collecting organizations, it is how to balance data utility and data privacy because they are traded-off. To achieve these aims in datasets, there are several well-known privacy preservation models to be proposed such as data anonymization models [34] [35] [36] [37] [38] [39] [40] [41] [42] [43] [44], data anatomization models [45] [46] [47] [48], and aggregate query frameworks [49]. Moreover, we further see that some privacy preservation models have been proposed, they are based on data anonymization in conjunction with aggregate query frameworks such as k-Likeness [50] and (l p1 , .…”
