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 ). In this way, a sufficient security can be retained when a plurality of users share a single information processing apparatus.
