Preventing information leakage between collaborating organisations

Information sharing and protection against leakage is a critical problem especially for organisations having sensitive information. Sharing content between individuals in the same organisation extends to exchanging and sharing content between collaborating organisations. In this paper we propose a novel solution for preventing shared information between collaborating organisations from getting leaked to unauthorised users inside the distination organisation or out side it. In addition, once the content is in the hands of authorised users our solution prevents unethical authorised users from leaking such content to other users in the same organisation or third parties.
