| Research Abstract |
In order to publish the social network data to provide the data to many data analysts, we should apply anonymization for protecting users' privacy in the social network service. We investigate the useful and secure anonymization algorithm for social network data. Especially we focus on two anonymization measure named k-degree and k-automorphism, and we propose the algorithms which can deal with the social network graph with node attributes and the algorithms. In addition we propose the algorithms which can keep the feature of original SN data after anonymization.
