This enables secure data processing even in untrusted environments. Services such as MEVAL have been put to practical use as a service that enables fast and secure use of secret operations. MEVAL offers a wide range of computational functions and facilitates cross-company analysis. In addition, MEVAL is a paid service. However, there is a demand for a simplified version of secret computation that general users can use. In this study, we propose a simplified secret computation system that is available for free. Specifically, we investigated applications on the App Store that use spreadsheets to understand general user demand. Based on the applications surveyed, we identified the necessary features for simplified secret computation. Additionally, we implemented a secret computation system using a spreadsheet-based approach.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1941","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2024論文集"}],"bibliographicPageStart":"1934","bibliographicIssueDates":{"bibliographicIssueDate":"2024-10-15","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T01:45:31.285568+00:00","updated":"2025-03-06T06:12:37.161421+00:00"}
