Abstract
Multiple service servers can store identification tags, which identify each user, after associating the identification tags with the identification tags of other users; and can also store identification data, which uniquely identifies users across multiple service servers, after associating the identification data with an encryption key for each identification datum. A management server device stores as identification data the user address data encrypted by means of an encryption key that has been generated for each identification datum. A gateway server device receives the identification tags from a first service server, receives the other identification tags associated with the first identification tags, receives the encryption keys associated with the other identification tags, and obtains the encrypted data from the management server. The gateway server device then decodes the encrypted information, and commands delivery that uses the obtained address data.
