JOINT OWNERSHIP OF PROTECTED INFORMATION

Disclosed herein is a system and method for managing a collaborative document that is owned by two different users who belong to different organizations. The users first create a document that will be owned by both users. Both users are also granted full ownership rights in the document. The users then contribute to the document by providing information that may be confidential to their organization. The users want to ensure that they can cut off access to the confidential information if and when the relationship between the users or organizations sours. When one of the users with full ownership privileges decides to end the cooperation with the other users, that user simply revokes access to the document to the other user. As a result of the revocation all users are no longer able to see or access the entire document. In this way the confidential information of all parties is protected.
