considered an important issue, and Provable Data Possession (PDP) is a solution to this problem. In contrast to Public PDP, where data integrity is audited by a trusted third party, Private PDP is a model where data integrity is verified between the data owner and the Cloud Service Provider (CSP). As it is difficult to completely prevent fraud by third parties, the model of Private PDP is useful as it does not require a third party: as Private PDP is a bilateral audit, there is no entity to judge which claim is correct if integrity cannot be proven. In this paper, we propose a scheme in which a blockchain is intervened in the process of data storage and integrity verification, which enables bilateral private integrity verification and, in case of data corruption, can determine whether the data custodian or the CSP has made a false declaration.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"734","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2023論文集"}],"bibliographicPageStart":"727","bibliographicIssueDates":{"bibliographicIssueDate":"2023-10-23","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
