Recently, the importance of information management has been getting higher. However, it is costly to set up the information management system.

 Users can perform the information management system with only a piece of Information CD-R. If a user, who stores any information in CD, designates people in certain Class (Level) in advance that will see the information, the designated people with ID and password provided can see only the information. The user can set the information in order not to be stored and printed.
