<p>The invention reduces a communication load when uploading processed data from a user device to a second system, after the data has been downloaded from a first system to the user device and processed in the user device. A process instruction receiving unit (72) receives a process instruction operation for which substitute data for original data is the item for processing. The following are sent from the user device (10) to a data processing device (30): original data acquisition-use information, which is for the purpose of acquiring the original data from a storage device; and processing instruction information related to the nature of the processing instruction operation performed on the data for processing. On the basis of the received original data acquisition-use information, the original data is acquired from the storage device, and on the basis of the received processing instruction information, the original data is processed, thereby generating process data.</p> |
