Abstract
Abstract Watermark detection in an image or the like can be optimized by exploiting the innate biases in the image to emphasize the watermark signal. The watermark signal can be trial-located with different origins in the image to find one that yields improved results. Similarly, the image can be processed (e.g., by changing resolution, rotation, or compression) so as to change the innate biases to better reinforce the watermark signal. Compression of an image can be done in accordance with a desired identifier, with the compressor deciding which image components to retain and which to discard based, in part, on the identifier that is to be associated with the image. The techniques are also applicable to other forms of content, such as audio.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
62 words
A method of steganographically encoding digital content with digital watermark data, comprising: receiving first uncompressed content data representing digital content; processing said first content data to discern components of said content; and identifying certain of said components that may be omitted to effect compression of said content, and whose omission would tend to encode the digital content with said digital watermark data.
Claim 2
Independent Claim
62 words
A method of steganographically encoding digital content with digital watermark data, comprising: receiving first uncompressed content data representing digital content; processing said first content data to discern components of said content; and identifying certain of said components that may be omitted to effect compression of said content, and whose omission would tend to encode the digital content with said digital watermark data.
Claim 3
Dependent Claim
27 words
The method of claim 1 that further includes omitting said identified components to yield a compressed version of the content that also conveys said digital watermark data.
Claim 4
Dependent Claim
10 words
The method of claim 1 wherein the content comprises audio.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein the content comprises visual information.
Claim 6
Dependent Claim
10 words
An apparatus for practicing the method of claim 1 .
Claim 7
Independent Claim
61 words
A method of processing digital content to associate a desired identifier therewith, comprising: receiving first uncompressed content data representing digital content; processing said first content data to discern components of said content; and identifying certain of said components that may be omitted to effect compression of said content, and whose omission would tend to associate the desired identifier with said content.
Claim 8
Independent Claim
61 words
A method of processing digital content to associate a desired identifier therewith, comprising: receiving first uncompressed content data representing digital content; processing said first content data to discern components of said content; and identifying certain of said components that may be omitted to effect compression of said content, and whose omission would tend to associate the desired identifier with said content.
Claim 9
Dependent Claim
13 words
The method of claim 6 wherein the desired identifier comprises digital watermark data.
Claim 10
Dependent Claim
26 words
The method of claim 6 that further includes omitting said selected components to yield a compressed version of the content having the desired identifier associated therewith.
Claim 11
Dependent Claim
25 words
The method of claim 8 wherein omission of said selected components serves to steganographically encode digital watermark data in said compressed version of said content.
Claim 12
Dependent Claim
10 words
The method of claim 6 wherein the content comprises audio.
Claim 13
Dependent Claim
11 words
The method of claim 6 wherein the content comprises visual information.
Claim 14
Dependent Claim
10 words
An apparatus for practicing the method of claim 6 .
Claim 15
Dependent Claim
39 words
In a method of compressing uncompressed content data, the method including selectively omitting certain components of content to effect compression thereof, an improvement wherein said omitting of content components also serves to associate a desired identifier with said content.
Claim 16
Dependent Claim
39 words
In a method of compressing uncompressed content data, the method including selectively omitting certain components of content to effect compression thereof, an improvement wherein said omitting of content components also serves to associate a desired identifier with said content.
Claim 17
Dependent Claim
16 words
The method of claim 13 wherein the desired identifier comprises steganographically encoded, plural-bit digital watermark data.
Claim 18
Dependent Claim
10 words
A compressor that practices the method of claim 13 .
