  • Patent number: 7574440
    Abstract: When a user, who has logged onto an information processing apparatus (100), executes a logoff procedure, a saving unit (160) executes the following processes. Firstly, from among the files residing in a data storage unit (110), any files that are recognized as requiring a security protection and hence are to be saved are copied into an external storage device (300) via a network (200), and the original files in the data storage unit (110) are then deleted. At this moment, the address of the copy destination is stored, as management information, into a portable information recording medium (400) possessed by the user. When the user logs onto the information processing apparatus (100) again, a restoring unit (170) restores, based on the management information stored in the portable information recording medium (400), the files saved in the external storage device (300) into the data storage unit (110).
