forensic investigation, a risk-communication can be poor because the interaction is hold between experts and non-experts. This problem surfaces as the problem of not being able to show the appropriateness of the investigation contents and cost. In this paper, we propose a risk-communicator to be used between a forensic investigation company and its client. Also, we show that forensic investigation selection can be formulated as a discrete optimization problem, and that the most cost-effective investigation can be derived using the proposed equation. In our method, the relationship between the residual risk and the investigation cost is formulated as a discrete optimization problem by quantifying the investigation rate of the cause and the investigation cost by measure of investigation workloads.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"498","bibliographic_titles":[{"bibliographic_title":"コンピュータセキュリティシンポジウム2021論文集"}],"bibliographicPageStart":"492","bibliographicIssueDates":{"bibliographicIssueDate":"2021-10-19","bibliographicIssueDateType":"Issued"}}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":214467,"updated":"2025-01-19T16:37:09.017973+00:00","links":{},"created":"2025-01-19T01:15:17.053272+00:00"}
