The compressive mechanism, one of the mechanisms that provide differential privacy, reduces the output error by compressing sparse data containing many zeros into low-dimensional data using a sensing matrix and reducing the noise to be added. However, there seems to be less effectiveness of the noise reduction from the viewpoint of the sensitivity. In this study, we propose a method for reducing the output error of the differential private mechanism by using a sparse sensing matrix that satisfies the L1 Restricted Isometry Property. We theoretically evaluate the output error of the proposed method and compare it with that of existing mechanisms. We also discuss the properties of the proposed method through experiments using mesh population data.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1338","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1324","bibliographicIssueDates":{"bibliographicIssueDate":"2024-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"65"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00239247","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"id":239367,"links":{}}
