Thus, obtaining the optimal combination of measures to reduce one risk while considering other risks has become a major issue. Because risk decisions involve multiple participants, such as a manager, customer, and employee, communication between all decision makers is important for reaching an agreement on the necessary risk measures. Moreover, due to opposing factors such as security, privacy, and development cost, it is not always easy to find the optimal combination of measures that reduce the risk and are agreeable to all decision makers. Therefore, this situation would benefit from the development of a \“multiple risk communicator” (MRC) with the following functions: (1) a model of the support role of the risk specialist, (2) an optimization engine, and (3) a display of the computed results for viewing by the decision makers. In this paper, we propose a design for developing the MRC program and present an example implementation. Then, we apply the results to problems of personal information leakage, illegal copying, and internal control. Keywords: security, privacy, risk, risk communication, discrete optimization.
