Abstract

Abstract A print management system includes a policy (113) 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 (130) are managed by a print management system (112). Each printer (130) can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system (112) routes the print job to a printer (130) that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian 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 on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 79 words
A document forgery protection printing method comprising: processing an image of a document; determining forgery protection requirements for the document to be printed; determining a protection level to be applied to the document based on the determined forgery protection requirements; selecting a printer from a plurality of printers that can print the document; and based on the determined protection level, printing at least one watermark on the document that corresponds to the determined protection level using the selected printer.
Claim 2
Dependent Claim 89 words
A document forgery protection printing system, comprising: at least one image processor that processes an image of document including at least one page; at least one server having a print management system and a policy that determines a forgery protection level for the document; a plurality of printers, each printer able to print the document and able to apply at lest one protection level to the document by printing at least one watermark including copy evidence and tracing information on the document that corresponds to the determined protection level.
Claim 3
Dependent Claim 23 words
A method or system according to claim 1 or 2, wherein the copy evidence and/or the tracing information is encoded in the watermark.
Claim 4
Independent Claim 20 words
A method or system according to any preceding claim, wherein the copy evidence varies with each page of the document.
Claim 5
Independent Claim 37 words
A method or system according to any one of the preceding claims, wherein the watermark comprises the contents of each page printed using invisible fluorescing toner or ink and offset from the visible contents of each page.
Claim 6
Independent Claim 40 words
A method or system according to any one of the preceding claims, wherein the tracing information is digitally signed and encoded in a glyph and printed using invisible fluorescing toner or ink and located in a margin of each page.
Claim 7
Independent Claim 26 words
A method or system according to any one of the preceding claims, wherein the watermark comprises random generated patterns printed using invisible fluorescing toner or ink.
Claim 8
Independent Claim 23 words
A method or system according to any one of the preceding claims, wherein the watermark is printed using fluorescing black toner or ink.
Claim 9
Dependent Claim 35 words
A method or system according to claim 8, wherein the watermark comprises fixed portions or random portions of each page or content dependent portions of each page printed using the fluorescing black toner or ink.
Claim 10
Dependent Claim 30 words
A method or system according to claim 7 or 9, wherein the randomly generated patterns or random portions of each page are encoded in a glyph and preferably digitally signed.
