Abstract
A method for preserving a digitally signed document (160) in a digital data preservation system (10). A secure preservation request (176) combines the document (160) with a preservation signature (174) that is generated using an identification mark (172) and the document's associated digital signature (168). Once the document (160) is authenticated by the digital preservation system vendor, both the document (160) and the identification mark (172) are recorded onto preservation media (210) in human-readable form.
