摘要

A personal information managing device issues a personal information registration certificate corresponding to personal information one to one and sends the issued personal information registration certificate to a service providing device through a user terminal. The user terminal checks the personal information registration certificate, so that the user terminal confirms that the personal information managing device has not falsified the personal information. Further, when personal information is transmitted/received, the user terminal and the service providing device check the relationship between the personal information registration certificate and the personal information, so that the service providing device confirms that the personal information managing device has not falsified personal information. Moreover, when sending personal information, the personal information managing device attaches its signature, so that the personal information managing device confirms that the service providing device has not falsified the personal information.
