Owner registration service system and information service method therefor

摘要

To an article manufactured by a maker, an ID recognition unit such as a contactless IC microchip in which a unique article ID is stored is attached. In a data base of an owner registration service company, the article information including the article ID and a current owner of an article are registered for each article. When a user purchases an article from a store, the article ID in the ID recognition unit and the personal information in the card for the article are sent to an authentication organ. When the authentication organ requests an updating of the owner to the owner registration service company by these information, the owner registration service company updates the owner information and the like included in the article information associated with the article ID in the data base.
