According to the embodiment described above, the blockchain 5 can be used to record multiple user association information that associates the user comprehensive information with all the users whose user information was used for the user comprehensive information. As a result, it is possible to verify how the user information of the users used for the comprehensive user information is being used, using the multiple user association information recorded using blockchain 5. .

Note that the blockchain 5 may also be used to record each user's location information (for example, movement history of a mobile terminal). Thereby, the location information of each user can be managed on the blockchain 5. Furthermore, if the user's location information managed on the blockchain 5 matches a predetermined benefit granting condition, a predetermined benefit may be granted to the user. For example, one or more stamp granting bases are predetermined as a benefit granting condition, and if the user's location information managed on the blockchain 5 matches the stamp granting base, a predetermined benefit is granted to the user. Give. As a result, the blockchain 5 can be used to manage location information of participating users, for example, in a stamp rally that goes around a plurality of stamp giving locations.

Furthermore, as this can improve the overall service quality of systems that provide information services, for example, it is possible to achieve goal 9 of the United Nations Sustainable Development Goals (SDGs): Developing resilient infrastructure. It will be possible to contribute to "promoting sustainable industrialization and expanding innovation."
