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.enlabeldigital watermarkinghard copy006conference paper
