  • Method for accessing information
    Patent number: 6728888
    Abstract: An information accessing method permits the user data belonging to a client-server system to be accessed by a user belonging to another client-server system under proper security and controls the permission for accessing the user data according to the security ranks of the user whose data is to be accessed and the user who wants to access the data. When a client unit issues a request for accessing the user data of the user belonging to the other client-server system, the request for access is sent to an ID conversion unit through a user ID management unit. The ID conversion unit operates to convert a user ID into a guest ID by referring to an ID conversion table, and then sends the request for access to a user ID management unit. The user ID management unit makes sure that the guest ID is registered by referring to the user ID table.
