the number of cloud computing users has been soaring, it is solicited to establish a secure computing platform where people can employ machine learning algorithms while preserving privacy of data. In this paper, we propose a privacy-preserving decision tree classification protocol using ring-LWE-based homomorphic encryption. It applies to cloud computing system with three-party: a client who has sensitive data, a model holder who has a pre-trained decision tree, and an outsourced server that supplies computing resource. To protect data privacy, input data and tree construction are encrypted by a client and a model holder, respectively, before being sent to an outsourced server. We demonstrate that the proposed privacy-preserving decision tree classification protocol works within a practical time for several public data sets.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"327","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2019論文集"}],"bibliographicPageStart":"321","bibliographicIssueDates":{"bibliographicIssueDate":"2019-10-14","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2019"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
