Sun, Xiaoxun, Wang, Hua and Zhang, Yanchun (2012) On the identity anonymization of high-dimensional rating data. Concurrency and computation: Practice and experience, 24 (10). pp. 1108-1122. ISSN 1532-0626

Abstract

In this paper, we mitigate a privacy threat to a large survey rating data set using an anonymity principle. We apply the flag matrix to formulate the problem, through which we provide a greedy approach to anonymize rating data. Extensive experiments confirm that our technique produces anonymized data sets that are highly useful and preserve the key statistical properties.
