Pkm-anonymity and ε-differential privacy are privacy protection notions proposed by Kobayashi et al and Dwork et al., respectively, in different contexts, and the relationship between the two is not fully clear. In previous research, the authors introduced the property of record-independence, which states that the processing of one record does not affect the values of other records, and showed the relationship between Pk-anonymity and ε-differential privacy when an anonymization method satisfies record-independence. In this paper, we show that, under the same conditions as the above relationship between Pk-anonymity and ε-differential privacy, Pkm-anonymization algorithms satisfy ε-differential privacy. Since it has already been shown that Pkm-anonymity includes km-anonymity, these relationships can also be used to show the relationship between km-anonymity and ε-differential privacy. Next, we will conduct numerical experiments to quantitatively evaluate the relationship between the parameters of Pkm-anonymity and ε-differential privacy.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告セキュリティ心理学とトラスト（SPT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-11-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2024-SPT-57"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":241409,"updated":"2025-01-19T07:40:45.426448+00:00","links":{},"created":"2025-01-19T01:45:59.785312+00:00"}
