A service providing device () includes: one-time PW generating processing section () which generates, for each operation device (), authentication information for use in authentication processing carried out by the service providing device () in a case where the service providing device () is accessed by a display processing device (); and an image data generating processing section () which (i) generates operation data including the authentication information generated and processing specifying information specifying the authentication processing, and (ii) transmits the operation data thus generated to the operation device ().

Data providing device, operation device, and data processing device

The present invention provides a transmitting/receiving method capable of selecting a combination of communication media of the own and its counterpart reflecting the preference of the user or an application for each of flows on communication terminals and capable of doing execution without being known by counterpart the preference information. It presents means for selecting a combination of CoAs (the CoA of the communication counterpart and that of the own) of the Mobile IP referring to the preference information of the application when communication terminals transmit/receive one or more flows (data flows) through one or more paths (communication channels). In consideration of combinations of flows and paths, the score is calculated for the combinations, and transmitted to the counterpart terminal of the communication, the approval is obtained to select the optimum path. As a result, the CoA suitable to the preferences of both parties can be selected for each flow.
