Abstract
Abstract Image, video, or audio data is encoded with both a frail and a robust watermark. The two watermarks respond differently to different forms of processing (e.g., copying the object may render the frail watermark unreadable), permitting an original object to be distinguished from a processed object. Appropriate action can then taken in response thereto.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
53 words
A method comprising: encoding a set of sampled data with a first watermark that is designed to withstand at least one generation of distortion, and a second watermark that is designed not to withstand even a single generation of distortion; and distributing the sampled data, or a tangible representation thereof, to the public.
Claim 2
Independent Claim
53 words
A method comprising: encoding a set of sampled data with a first watermark that is designed to withstand at least one generation of distortion, and a second watermark that is designed not to withstand even a single generation of distortion; and distributing the sampled data, or a tangible representation thereof, to the public.
Claim 3
Dependent Claim
14 words
The method of claim 1 in which the sampled data corresponds to a graphic.
Claim 4
Dependent Claim
15 words
A printed object having the graphic produced by the method of claim 2 printed thereon.
Claim 5
Dependent Claim
13 words
The method of claim 1 in which the sampled data corresponds to audio.
Claim 6
Dependent Claim
16 words
A tangible machine readable storage medium having audio encoded in accordance with claim 4 stored thereon.
Claim 7
Dependent Claim
17 words
The method of claim 1 wherein said distortion comprises compression and subsequent decompression with a lossy process.
Claim 8
Dependent Claim
12 words
The method of claim 6 wherein the sampled data corresponds to audio.
Claim 9
Dependent Claim
12 words
The method of claim 6 wherein the sampled data corresponds to video.
Claim 10
Dependent Claim
25 words
The method of claim 1 , wherein the watermarking of at least the first watermark is effected by slight alterations to the sampled data's color.
Claim 11
Dependent Claim
15 words
The method of claim 9 , wherein the distortion comprises at least scanning and reprinting.
Claim 12
Dependent Claim
83 words
A computer storage medium having instructions stored thereon for causing a computer programmed thereby to perform a method comprising: encoding a set of sampled data with a first, relatively robust, steganographic watermark; and encoding said set of sampled data with a second, relatively frail, steganographic watermark; wherein the first watermark is reliably conveyed with the data notwithstanding various distortions, and the second watermark is lost with such distortions, wherein an original set of said sampled data can be distinguished from a distorted reproduction.
Claim 13
Dependent Claim
83 words
A computer storage medium having instructions stored thereon for causing a computer programmed thereby to perform a method comprising: encoding a set of sampled data with a first, relatively robust, steganographic watermark; and encoding said set of sampled data with a second, relatively frail, steganographic watermark; wherein the first watermark is reliably conveyed with the data notwithstanding various distortions, and the second watermark is lost with such distortions, wherein an original set of said sampled data can be distinguished from a distorted reproduction.
Claim 14
Dependent Claim
14 words
The computer storage medium of claim 11 wherein said sampled data corresponds to audio.
Claim 15
Dependent Claim
17 words
The medium of claim 11 wherein said distortions comprise compression and subsequent decompression with a lossy process.
Claim 16
Dependent Claim
12 words
The medium of claim 13 wherein the sampled data corresponds to audio.
Claim 17
Dependent Claim
12 words
The medium of claim 14 wherein the sampled data corresponds to video.
