<p><P>PROBLEM TO BE SOLVED: To provide an authentication method which makes an amount of authentication information-setting processing to a server device at authentication information generation independent of the number of server devices. <P>SOLUTION: A converting device receives service data which include first connection destination data and authentication information on a user already authenticated, and generates second connection destination data which identifies the first connection destination data, and then correlates the authentication information on the user already authenticated with the first and second connection destination data to transmit them to a relaying device. Then, the converting device transmits the service data obtained by replacing the first connection destination data with the second connection destination data to a client and the client transmits the second connection destination data selected by the user to the relaying device. The relaying device transmits the authentication information to a server which the first connection destination data indicate on the basis of the authentication information which corresponds to the second connection destination data transmitted from the client and the first connection destination data, and also transmits the address of the server to the client. Then, the client communicates with the server by using the address and the authentication information to solve the problem. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
