In an information processing apparatus which transfers target information to an external data processing device to process the information, and saves the processed information, a data management unit stores second identification information corresponding to the target information in association with the target information to which first identification information is attached. The first changing unit deletes the first identification information from the target information and adds the corresponding second identification information to the target information in the data management unit. The transfer unit transfers the target information processed by the first changing unit to the external data processing device.
