<P>PROBLEM TO BE SOLVED: To suppress connection from an unauthorized user which is not normally permitted in connection between a user terminal and a service server through a network and to realize a safe connection system in multi-connection to a plurality of new service servers. <P>SOLUTION: In a connection procedure from a user terminal accepting permission from a conventional authentication server to a service server, there may be risk of unauthorized connection due to unauthorized processing from the user. Thereby, a connection system from the service server side to the user terminal is adopted without allowing the user to participate connection processing. Since the connection system from the service server side is adopted, security of multi-connection can be improved as compared with a conventional method. <P>COPYRIGHT: (C)2009,JPO&INPIT |
