Administrators of DaaS is the third party from the data owner, privacy-preserved data storage and query architectures are needed.  In this paper we propose a privacy preserving query method hiding schema information and multiple query condition for DaaS. A range query method of numerical data using bloom-filter [6] can also apply for keyword matching for string data. Then the proposed method generates an index for a tuple which is combined index for all attribute values of the tuple. The method also translates conjunctive query conditions into an encrypted condition using an index attached to each tuple. An adversary can't any information about the relation schema of the table and query conditions are applied from the query log, then user can store and search privacy sensitive data to DaaS.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"168","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"163","bibliographicIssueDates":{"bibliographicIssueDate":"2008-09-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"88(2008-DBS-146)","bibliographicVolumeNumber":"2008"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
