    Abstract: There has been a growing interest in sharing and mining social network data for a wide variety of applications. In this paper, we address the problem of privacy disclosure risks that arise from publishing social network data. Specifically, we look at the vertex re‐identification attack that aims to link specific vertex in social network data to specific individual in the real world. We show that even when identifiable attributes such as names are removed from released social network data, re‐identification attack is still possible by manipulating abstract information. We present a new type of vertex re‐identification attack model called neighbourhood‐pair attack. This attack utilizes the information about the local communities of two connected vertices to identify the target individual. We show both theoretically and empirically that the proposed attack provides higher re‐identification rate compared with the existing re‐identification attacks that also manipulate network structure properties. The experiments conducted also show that the proposed attack is still possible even on anonymised social network data. Copyright © 2015 John Wiley & Sons, Ltd.

    Abstract: Enterprises today are dealing with the massive size of data, which have been explosively increasing. The key requirements to address this challenge are to extract, analyze, and process data in a timely manner. Clustering is an essential data mining tool that plays an important role for analyzing big data. However, large‐scale data clustering has become a challenging task because of the large amount of information that emerges from technological progress in many areas, including finance and business informatics. Accordingly, researchers have dealt with parallel clustering algorithms using parallel programming models to address this issue. MapReduce is one of the most famous frameworks, and it has attracted great attention because of its flexibility, ease of programming, and fault tolerance. However, the framework has evident performance limitations, especially for iterative programs. This study will first review the proposed iterative frameworks that extended MapReduce to support iterative algorithms. We summarize these techniques, discuss their uniqueness and limitations, and explain how they address the challenging issues of iterative programs. We also perform an in‐depth review to understand the problems and the solving techniques for parallel clustering algorithms. Hence, we believe that no well‐rounded review provides a significant comparison among parallel clustering algorithms using MapReduce. This work aims to serve as a stepping stone for researchers who are studying big data clustering algorithms. Copyright © 2015 John Wiley & Sons, Ltd.
