Abstract

This invention is a method for annotating and redacting a final-form document archived in a computerized system where it is important that the fidelity of the final form document is preserved. More particularly, this method allows final-form documents containing objects such as texts, graphics and images to be annotated or redacted by other objects carried in the same data stream without compromising the integrity of the original document.
