In this embodiment, the data provider may be the owner of the user data, and the data receiver may be the user of the user data. For example, the data consumer may be one server and the data provider another server, both operated by different operators. As another example, the data consumer may be an application installed on the user terminal that is connected to an application server of the data consumer, and the data provider may be another server and communicate with the data consumer.
