Existing k-anonymization methods assume that a data owner has only a personal record and ensure k-anonymity for a record. However, actually, each data owner has multiple personal records with having the same identifier. In this case, k-anonymized records may break k-anonymity because the number of candidates for a data owner can narrow down less than k by linking records having the same identifier. This paper proposes a data anonymization method which prevents such record linking.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"91","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2012論文集"}],"bibliographicPageStart":"84","bibliographicIssueDates":{"bibliographicIssueDate":"2012-10-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2012"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:37:39.747690+00:00","updated":"2025-01-21T17:34:57.390082+00:00"}
