A print management system includes a policy that determines a protection
level for a document to be printed. The document is printed using forgery
detection and deterrence technologies, such as fragile and robust
watermarks, glyphs, and digital signatures, that are appropriate to the
level of protection determined by the policy. A plurality of printers are
managed by a print management system. Each printer can provide a range of
protection technologies. The policy determines the protection
technologies for the document to be printed and the print management
system routes the print job to a printer that can apply the appropriate
protections and sets the appropriate parameters in the printer. Copy
evidence that can verify that a document is a forgery and/or tracing
information that identifies the custodian(s) of the document and
restrictions on copying of the document and use of the information in the
document are included in the watermark that is printed with the document
information. A document can be verified as an original or a forgery by
inspecting the copy evidence and/or tracing information in the watermark.
