This paper presents a security system for enforcing security policies throughout distributed environments. The aspects of the system dealing with the protection of digital data using object labeling and mandatory encryption at the operating system level are described briefly; the main focus is on the protection afforded by the system in the analog domain. This is accomplished by embedding multiple digital watermarks identifying the copyright owner, the identity of the object, and of users accessing the object into any markable object accessed by users.
