A data distribution intermediary device for mediating data exchange between a data provision device of a data provider that collects and provides personal data provided by a data owner and a data usage device of a service provider that provides service usage data related to the personal data, the data distribution intermediary device comprising:
a personal data metadata management unit configured to acquire personal data metadata that is metadata of the personal data stored in the data provision device;
a service usage data attribute management unit configured to generate service usage data metadata, which is metadata related to the service usage data, based on terms of service related to distribution and usage of the personal data;
a metadata attribute difference detection unit configured to detect a difference between the personal data metadata and the service usage data metadata;
a personal data conversion determination unit configured to determine a necessity of conversion processing of the personal data based on the difference of the metadata detected by the metadata attribute difference detection unit; and
a personal data conversion processing unit configured to convert the personal data to corresponding service usage data, wherein
