Abstract
A job device for increasing security of job data includes a CPU that encrypts job data while saving job data required in execution of a job. The CPU saves part of the data in RAM, and saves the remaining stored file in an HDD. When the job ends, part of the job data for the job in the RAM is deleted. Part of the job data is therefore completely eliminated as a result of this deletion, and it is not possible to know the complete job data even if the HDD is removed and checked.
