Abstract
Access control in a collaboration system is realized, in which, even when only particular one of users working together has access permission to a resource, the other users are allowed to access the resource under certain conditions.
The collaboration system includes multiple terminals 100 exchanging data through a network to perform collaborative work, and a collaboration server 200 that acquires a resource in response to a request from each terminal 100 and sends the resource to the terminal 100. When an access request for an access-controlled resource is made from a user terminal 100 not having the access permission to the resource, the collaboration server 200 uses access authorization of a session owner to the resource to acquire the resource.
