3 つの情報共有モデルを取り上げ,悪意の例として,情報源の信用度を実際よりも高く偽る行為をモデルに組み込む.悪意の効果を評価し,情報源の信用度が低いことよりも,低い信用度を高く偽ることの方が大幅な悪影響を与えることを明らかにする.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ(CSEC)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2020-11-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"17","bibliographicVolumeNumber":"2020-CSEC-91"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":207943,"updated":"2025-01-19T18:59:43.019841+00:00","links":{},"created":"2025-01-19T01:09:32.859805+00:00"}
