Novel Method to Watermark Anonymized Data for Data Publishing
Yuichi Nakamura, Yoshimichi Nakatsuka, Hiroaki Nishi · IEICE Transactions on Information and Systems · 2017
In this study, an anonymization infrastructure for the secondary use of data is proposed. The proposed infrastructure can publish data that includes privacy information while preserving the privacy by using anonymization techniques. The infrastructure considers a situation where ill-motivated users redistribute the data without authorization. Therefore, we propose a watermarking method for anonymized data to solve this problem. The proposed method is implemented, and the proposed method's tolerance against attacks is evaluated.
