<p>A data processing apparatus capable of using, without change, a password used at the time of backup as a password at the time of restoration to thereby realize backup and restoration which are high in security and user-friendliness. Upon being backed up into an external storage medium, data stored in a box in the data processing apparatus and protected by password information is encrypted with an encryption key generated based on the password information and is stored into the external storage medium. Upon restoration of the encrypted data from the external storage medium to a multifunction peripheral, password information input by a user is set as a new password, and the data decrypted with a decryption key generated based on the password information is protected with the new password.</p> |
