IDENTIFICATION MANAGING SYSTEM FOR AUTHENTICATION OF ELECTRONIC DEVICE

摘要

In operation of a conventional vertical integration system a primary user cannot provide services to a secondary user belonging to other service group. An identification managing server is proposed to carry out the retrieval of a master-slave relation information by using common identification information as a key and outputs an assurance including its result when the identification managing server receives an assurance request output from a first judgment server at a request of a second judgment server from a first electronic device used by a primary user. Further, the first judgment server outputs an assured service based on such assurance to the second judgment server in order for the primary user to have services from the other vertical integration system to which the secondary user belongs.
