Recently, privacy protection attracts more and more research efforts especially for social network data. In the literature, most of existing approaches assume that social data are independent to each other which is not the case in the real world applications. In this paper, we are the first attempt to investigate the privacy protection issue when social data are correlated. We model the correlation...
In the era of big data, privacy becomes a challenging issue which already attracts a good number of research efforts. In the literature, most of existing privacy preserving algorithms focus on protecting users' privacy from being disclosed by making the set of designated semi-id features indiscriminate. However, how to automatically determine the appropriate semi-id features from high-dimensional...
