Input image data is stored in local memory 10 and subjected to image processing, and then it is saved in a hard disk device 4. The image data that is read from the hard disk device 4 is stored in the local memory 10, and then printed as an image from a printing portion 3a or transmitted from a communication section 5 in data communication. When image data input is completed, image data is left stored in the local memory 10. Therefore, the image data is overwritten with random data and invalidated so that the image data is unreadable. Also, when image data processing is completed, image data is invalidated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data processing apparatus","description":"In local memory that stores image data, the image data is invalidated to prevent leakage of the image data.
