Abstract
Abstract An iterative encoding technique assesses trial watermark encoding of an object, and redresses any detected shortcomings in one or more successive re-encodings of the object. Other improvements concern web crawler-based watermark detectors, novel uses of meta-data in watermarks, applications of watermarks in merchandising, embedding of active computer code via watermarks, watermark-based asset management systems, watermark processing of computer system clock signals, and watermarks in labels and tags.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
44 words
A method of preparing watermarked entertainment content data for public distribution, comprising: compressing first data; decompressing the compressed data; assessing a result of said compression operation; and providing information obtained through said assessment to a watermarking process that is to watermark the entertainment content.
Claim 2
Independent Claim
44 words
A method of preparing watermarked entertainment content data for public distribution, comprising: compressing first data; decompressing the compressed data; assessing a result of said compression operation; and providing information obtained through said assessment to a watermarking process that is to watermark the entertainment content.
Claim 3
Dependent Claim
22 words
The method of claim 1 that includes using information obtained through said assessment in performing a watermarking operation on said content data.
Claim 4
Dependent Claim
15 words
The method of claim 2 that further includes publicly distributing the watermarked content thus produced.
Claim 5
Dependent Claim
20 words
A computer storage medium having stored thereon watermarked entertainment content data produced according to the method of claim 2 .
Claim 6
Dependent Claim
21 words
The method of claim 1 in which the first data comprises information that is to be used in said watermarking process.
Claim 7
Dependent Claim
21 words
The method of claim 1 in which the first data comprises data that is to be used in said watermarking process.
Claim 8
Dependent Claim
15 words
The method of claim 1 which comprises assessing degradation through said compression and decompression operations.
Claim 9
Dependent Claim
19 words
The method of claim 1 which comprises assessing degradation of the first data through said compression and decompression operations.
Claim 10
Dependent Claim
27 words
The method of claim 1 which comprises using the first data, after said compression and decompression, as watermark data to be combined with said entertainment content data.
Claim 11

Claim 12
Dependent Claim
24 words
The method of claim 1 in which the first data represents plural-symbol auxiliary information with which the entertainment content data is to be watermarked.
Claim 13
Dependent Claim
19 words
A computer storage medium having stored thereon instructions causing a processor to perform the method of claim 1 .
Claim 14
Independent Claim
31 words
A method of enhancing robustness of a steganographically embedded signal to distortion, comprising preconditioning the signal by determining components thereof that are expected to survive said distortion, and removing other components.
Claim 15
Independent Claim
31 words
A method of enhancing robustness of a steganographically embedded signal to distortion, comprising preconditioning the signal by determining components thereof that are expected to survive said distortion, and removing other components.
Claim 16
Dependent Claim
34 words
The method of claim 13 in which the preconditioning comprises processing the signal with said distortion, wherein said distortion acts to determine components of the signal that survive said distortion, and removes other components.
Claim 17
Dependent Claim
24 words
The method of claim 14 in which processing the signal with distortion comprises processing the signal with a lossy process including compression and decompression.
Claim 18
Dependent Claim

Claim 19
Dependent Claim
19 words
A computer storage medium having stored thereon instructions causing a processor to perform the method of claim 13 .
Claim 20
Dependent Claim
48 words
In a method of steganographically encoding a content signal with an auxiliary signal, an improvement comprising preconditioning the auxiliary signal prior to said encoding so as to better withstand expected degradation of the encoded content signal, and thereafter encoding the content signal in accordance with the auxiliary signal.
Claim 21
Dependent Claim
48 words
In a method of steganographically encoding a content signal with an auxiliary signal, an improvement comprising preconditioning the auxiliary signal prior to said encoding so as to better withstand expected degradation of the encoded content signal, and thereafter encoding the content signal in accordance with the auxiliary signal.
Claim 22
Dependent Claim
17 words
The method of claim 18 that further includes decoding the auxiliary signal from the encoded content signal.
Claim 23
Dependent Claim
33 words
The method of claim 18 in which the content signal includes components representing image data that are rendered to yield a visible impression to a viewer, and the steganographic encoding alters said components.
