<p>The present invention provides, for a connection from an unspecified communication device, an information processing system, information processing device configuring the information processing system, and communication connection method for between the communication device and the information processing device which are capable of securing communication security while simplifying operation in the communication device. In order to transmit image data to a multi-function device from a communication terminal device in order to printout the same, the multi-function device generates a one-time password that is limited in period of validity to a period related to the printout so as to display the same together with the SSID of the device itself upon a display unit, whereupon at the communication terminal device, the displayed SSID and the one-time password are input so as to make a connection in order to transmit image data. After completion of reception of the image data and start of the printout, even if the SSID and the password which have been displayed are used, it is not possible to connect from the communication terminal device to the multi-function device.</p> |
