Abstract

This paper presents a mechanism for embedding both immediately readable and steganographically hidden information in human-\-readable output, particularly in hard copy format. The mechanism is embedded within a domain inaccessible to unprivileged users in the operating system's Trusted Computing Base. A realization is presented which permits the embedding of such markings in arbitrary printing systems under the Microsoft Windows NT family of operating systems.
