Abstract
Abstract A carrier is watermarked and then an image is printed or displayed on this carrier. A watermark can then be read from the image. If the image is printed on the carrier, the watermark can be read from the printed image or from any copy of the printed image. If the watermark is displayed on the carrier, and the displayed image is then copied, the copies will bear the watermark.

Claims Analysis
Total Claims: 32
Claim 1
Independent Claim
85 words
A method of watermarking an image comprising the steps of, applying a first material on a substrate in a pattern corresponding to a digital watermark, said first material being transparent, printing an image on said substrate, said image having different characteristics in the areas where said first material is located, wherein the first material affects the printing of the image to embed the digital watermark in the printed image such that the digital watermark is readable from a digital image scanned from the printed image.
Claim 2
Independent Claim
85 words
A method of watermarking an image comprising the steps of, applying a first material on a substrate in a pattern corresponding to a digital watermark, said first material being transparent, printing an image on said substrate, said image having different characteristics in the areas where said first material is located, wherein the first material affects the printing of the image to embed the digital watermark in the printed image such that the digital watermark is readable from a digital image scanned from the printed image.
Claim 3
Dependent Claim
14 words
The method recited in claim 1 wherein said first material comprises a transparent wax.
Claim 4
Dependent Claim
19 words
The method recited in claim 1 wherein said first material is applied by using a wax sublimation printing process.
Claim 5
Dependent Claim
17 words
The method recited in claim 1 wherein said image is printed using an ink jet printing process.
Claim 6
Dependent Claim
30 words
The method recited in claim 1 wherein said first material is applied by using a wax sublimation printing process and said image is printed using an ink jet printing process.
Claim 7
Independent Claim
58 words
A method of watermarking an image comprising the steps of, applying a first material on a screen in a pattern that represents a digital watermark, projecting an image on said screen, said screen reflecting said image with different characteristics in the areas where said first material is located, whereby recordings of said projected image bear said digital watermark.
Claim 8
Independent Claim
58 words
A method of watermarking an image comprising the steps of, applying a first material on a screen in a pattern that represents a digital watermark, projecting an image on said screen, said screen reflecting said image with different characteristics in the areas where said first material is located, whereby recordings of said projected image bear said digital watermark.
Claim 9
Dependent Claim
13 words
The method recited in claim 6 wherein said screen is a movie theater.
Claim 10
Dependent Claim
19 words
The method recited in claim 6 wherein a series of images comprising a movie is projected on said screen.
Claim 11
Independent Claim
44 words
A method of watermarking recorded images comprising the steps of projected an image on a screen which has areas with different reflective characteristics in a pattern that represents a digital watermark, recording images from said screen, whereby the recorded images bear said digital watermark.
Claim 12
Independent Claim
44 words
A method of watermarking recorded images comprising the steps of projected an image on a screen which has areas with different reflective characteristics in a pattern that represents a digital watermark, recording images from said screen, whereby the recorded images bear said digital watermark.
Claim 13
Dependent Claim
19 words
The method recited in claim 9 wherein a series of images comprising a movie are projected on said screen.
Claim 14
Dependent Claim
75 words
A material suitable for printing comprising a substrate and a layer of material positioned on said substrate in a pattern that represents a digital watermark, said material being invisible to the human eye and affecting ink deposited on said substrate, wherein the first material affects the printing of an image to embed the digital watermark in the printed image such that the digital watermark is readable from a digital image scanned from the printed image.
Claim 15
Dependent Claim
75 words
A material suitable for printing comprising a substrate and a layer of material positioned on said substrate in a pattern that represents a digital watermark, said material being invisible to the human eye and affecting ink deposited on said substrate, wherein the first material affects the printing of an image to embed the digital watermark in the printed image such that the digital watermark is readable from a digital image scanned from the printed image.
Claim 16
Dependent Claim
11 words
The method recited in claim 11 wherein said material is transparent.
Claim 17
Dependent Claim
13 words
The method recited in claim 11 wherein said material is a transparent wax.
Claim 18
Dependent Claim

Claim 19
Dependent Claim
53 words
A screen on which images are projected, the screen comprising: a pattern of areas having different reflectivity or light absorption properties representing a digital watermark such that when an image is projected onto the screen, the areas modify the projected image so that the projected image on the screen bears the digital watermark.
Claim 20
Dependent Claim
53 words
A screen on which images are projected, the screen comprising: a pattern of areas having different reflectivity or light absorption properties representing a digital watermark such that when an image is projected onto the screen, the areas modify the projected image so that the projected image on the screen bears the digital watermark.

The screen of claim 15 wherein the pattern of areas is formed from a coating on the screen.
Claim 22
Dependent Claim
21 words
The screen of claim 15 wherein the pattern of areas is formed from a layer of adhesive applied to the screen.
Claim 23
Dependent Claim
69 words
An object for receiving a printed image, the object comprising: a substrate; and a material on the substrate in a pattern corresponding to a digital watermark, said material being operable to change characteristics of an image printed on the object according to the pattern to embed the digital watermark in the printed image such that the digital watermark is readable from a digital image scanned from the printed image.
Claim 24
Dependent Claim
69 words
An object for receiving a printed image, the object comprising: a substrate; and a material on the substrate in a pattern corresponding to a digital watermark, said material being operable to change characteristics of an image printed on the object according to the pattern to embed the digital watermark in the printed image such that the digital watermark is readable from a digital image scanned from the printed image.
Claim 25
Dependent Claim
13 words
