An information sharing system manages computing resources such as files and processes by virtually assigning them to a compartment that is a unique area identified by a group ID. As the information sharing system detects a file input event of an object by using the compartment, it authorizes only referring to files belonging to the same compartment or a lower order compartment. Additionally, as the information sharing system detects a file output event of an object, it allows files to be arranged within only the same compartment. By doing so, it is possible for remotely located users of a user group to share confidential information within the group and at the same time also share information ordinarily and more broadly.
