Abstract
There is disclosed a system and method of extending the labels on an encryption technique so that different users can utilize the same files under different rights established by both the user and the system administrator. This system and method take advantage of an extension of the file label which contains configuration capabilities and user rights and privileges to that file. The extended labeling is expandable so that several users can each be identified having specific rights and specific encryption capability with respect to the file.
