Abstract(in Japanese) (See Japanese page)
Abstract(in English) An anonymization infrastructure for secondary use of data has been proposed. The infrastructure was proposed to publish data that include sensitive and privacy information while preserving the privacy by anonymization techniques. The infrastructure should consider a situation that some data users might redistribute the data without permissions. To solve this problem, we propose a combined watermarking technique for anonymized data. We implemented and evaluated the proposed technique. Evaluation results show that the proposed technique is available even if 70 % of watermarked anonymized data are deleted or replaced, or the watermarked data is combined with another data that size is 95% of the watermarked data.
