<p><P>PROBLEM TO BE SOLVED: To carry out data communication by easily authenticating a one-time ID generated for each communication section when the data communication with a transmission-destination terminal is performed through a relay device. <P>SOLUTION: One-time IDs by the relay device 300 are generated by communication sections 410 and 420 and a one-time ID for the down communication session 420 between them is transmitted to a communication terminal 200. Then the one-time ID for the communication session 420 sent to the communication terminal 200 at the transmission destination is sent to the relay device 300 from the communication terminal 100 and when the one-time ID for the communication session 420 is registered in a database section 320 and its communication partner is not set yet, the relay device 300 connects the communication session 410 and 420 by a relay session to relay image transmission from the communication terminal 100 to the communication terminal 200. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
