Slicing:一种新的隐私保护数据发布方法

Slicing: A New Approach to Privacy Preserving Data Publishing

Tiancheng Li, Ninghui Li, Jian Zhang, Ian Molloy

摘要:

已经设计了几种匿名化技术,例如泛化和桶化,用于隐私保护微数据发布。最近的研究表明,泛化丢失了大量的信息,特别是对于高维数据。另一方面,桶化并不阻止成员身份泄露,也不适用于在准识别属性和敏感属性之间没有明确区分的数据。在本文中,我们提出了一种新的技术,称为切片,分区的数据水平和垂直。我们表明,切片保存更好的数据实用性比泛化,可用于成员披露保护。切片的另一个重要优点是它可以处理高维数据。我们展示了如何切片可以用于属性披露保护,并开发了一个有效的算法来计算切片数据,遵守l-多样性的要求。我们的工作负载实验证实,切片保留更好的实用性比泛化,是更有效的比桶化的工作负载涉及敏感属性。我们的实验还表明,切片可以用来防止成员披露。

英文摘要:

Several anonymization techniques, such as generalization and bucketization, have been designed for privacy preserving microdata publishing. 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. In this paper, we present a novel technique called slicing, which partitions the data both horizontally and vertically. We show that 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. We show how slicing can be used for attribute disclosure protection and develop an efficient algorithm for computing the sliced data that obey the l-diversity requirement. Our workload experiments confirm that slicing preserves better utility than generalization and is more effective than bucketization in workloads involving the sensitive attribute. Our experiments also demonstrate that slicing can be used to prevent membership disclosure.
