Dynamically generating sharing boundaries

Abstract:

A collaboration system provides network access to a plurality of content objects. The collaboration system facilitates collaboration interactions between particular users by allowing or denying network access to the plurality of content objects based on user invitations. A computing module observes and records user-to-user or user-to-content collaboration invitations over the plurality of content objects. On an ongoing basis, a collaboration network graph is constructed and maintained, with updates to the collaboration network graph being continually applied based on observed collaboration interactions. On demand, such as upon receipt of a user request for access to a content object, the updated collaboration network graph is consulted so as to generate a then-current sharing boundary. If the user that raised the user request is within the generated then-current sharing boundary, then access to the content object is granted, otherwise further processing is invoked to determine if the user should nevertheless be granted access.
