Risk Management to User Perception of Insecurity in Ambient Service

In recent years, Ambient service has attracted attention as a ubiquitous, future intelligence infrastructure. The Ambient service provides service suitable for user needs automatically by making a sensor and a computer cooperate, and gathering and analyzing the information about each user. However, with the Ambient service, in order to manage personal information, various risks, such as an information leakage, are assumed. In this research, about a risk of being assumed with the Ambient service, it analyzes from a viewpoint by the side of service provision and service use, and clarifies the proposed measures. Specifically, risk breakdown structure and the risk matrix which are the typical risk management methods of project management were used. These results extracted 40 factors as a risk factor of the Ambient service. As the main feature of countermeasure, for Risk Transference, a countermeasure, such as preparing a third party´s inspection on the service provision side, was proposed. Moreover, for Risk Mitigation, a countermeasure, such as a rule for a new specification corresponding to the Ambient service, was proposed. As mentioned above, the risk management of the Ambient service was proposed in this paper. A future subject is evaluating the effectiveness of the proposed countermeasure.
