Output system for secure image processing, image processing apparatus, and output method thereof

An output system comprising:

• an image processing apparatus;
• and
• a server connectable to a terminal device via a network, the terminal device requesting the image processing apparatus to output an image, wherein the server includes a controller configured to control:
• a first identification information obtaining unit configured to obtain, from the terminal device, identification information for identifying the terminal device;
• an identification information registration unit configured to register the identification information obtained by the first identification information obtaining unit when a request to register the identification information is received from the terminal device;
• a generating unit configured to generate output data for settings for outputting the image, the output data for settings including the identification information of the terminal device registered by the identification information registration unit;
• and
• a transmission unit configured to transmit the output data for settings generated by the generating unit to the terminal device, wherein the image processing apparatus includes a controller configured to control:
• a second identification information obtaining unit configured to obtain the identification information from the terminal device;
• a receiving unit configured to receive data relating to output of the image from the terminal device from which the second identification information obtaining unit obtains the identification information;
• a determination unit configured to, when the data received by the receiving unit includes the output data for settings, determine whether the identification information obtained by the second identification information obtaining unit is equal to the identification information included in the output data for settings;
• an available terminal registration unit configured to register the terminal device as an available terminal device, if the determination unit determines that the identification information obtained by the second identification information obtaining unit is equal to the identification information included in the output data for settings;
• and
• an output control unit configured to control an output process according to the data received by the receiving unit from the terminal device registered as the available terminal by the available terminal registration unit.
