Abstract
To achieve the Japanese government’s Society 5.0 initiative, the goal of which is to realize a better society by utilizing both the physical space and the virtual space created by computer networks, it is essential to ensure that the data used accurately reflect social trends and that the privacy of individuals is not violated. This paper discusses how to handle information on the actions and behavior of individuals when seeking to realize a society in which people can live with a sense of peace and safety. It first argues that, when applying the theoretical framework of the P2M (project and program management) to a social system construction program, it is necessary to consider not only positive but also negative scenarios at the program design stage. As we proceed with engineering experiments based on the positive scenarios, we should also take appropriate measures and develop usage rules to avoid falling into the negative scenarios. As an example, this paper describes a positive scenario in which we realize a better society 20 years from now by using IoT and AI, and a negative scenario in which personal security is threatened by monopolistic data management that may result from technological evolution. This paper proposes a hierarchical model for managing information on the activities of individuals. This model shows how a negative scenario can be averted and helps the development of the industry. The paper proposes that introducing a distributed data management system, such as a blockchain, would be an effective way to prevent the improper use or disclosure of private information.
