IMAGE FORMING APPARATUS AND METHOD OF CONTROLLING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus that stores the read data in a memory device such as an HDD and the like in the high security without forcing an operation load on a user. Ž<P>SOLUTION: The image forming apparatus includes: a key generation part for altering an encryption key to generate an encryption key different from the encryption key used up to that time for each alteration; an encryption part for encoding image data by the encryption key generated by the key generation part; a first memory for storing the encrypted image data; a second memory for storing the encryption key, and a table correlating the image data encrypted by the encryption key with the encryption key; and a decryption part for decrypting the data stored in the first memory by using the encryption key correlated by the table.
