APPARATUS AUTHENTICATION SYSTEM

摘要

An apparatus authentication system comprises a terminal, a data communication device connected to the terminal, and a service provider. The terminal encrypts stored apparatus information, generates authentication information, and sends user information on the data communication device and the encrypted apparatus information. The service provider decrypts the encrypted apparatus information by means of an apparatus authentication server, uses the decrypted apparatus information to check if the terminal is one that matches a service content provided by the service provider and, according to this authentication result, controls whether or not user information is to be sent to a user authentication server.
