In communication, information goes through the central server and users lose its control. Therefore, sensitive data might be revealed by government censorship in the future. To counter such a threat, it is necessary for data to set an expiration time and to be automatically deleted. In this paper, we propose a protocol that satisfies the above requirement by combining blockchain and secret sharing. This system differs from previous research in that it is not requiring trusted third parties or secure hardware and resistant to a Sybil attack.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2017論文集"}],"bibliographicIssueDates":{"bibliographicIssueDate":"2017-10-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2017"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:53:57.359086+00:00","id":187271,"links":{}}
