Abstract

Methods and systems include, e.g.,: (1) steganographically embedding location information in images, where the location information is obtained from remote sources like a cell phone network or remote GPS receiver; (2) steganographically embedding participant IDs in content to ensure proper billing and royalty tracking; (3) providing fair-use content management based upon digital watermark-tracked usage; (4) providing micro-payments based upon watermarked ID cards for retailers; and/or (5) providing watermarked logon cards, such as watermarked hotel room keys, to better provide internet logon access control. Other systems and methods are provided as well.

Claims

1. A method for providing royalty payments for content distributed via a network, said method comprising:

receiving registration information from a participant who requires royalty payments for content to be distributed;

assigning a unique identifier to the participant;

steganographically embedding the content with the identifier; and

associating a royalty payment action with the identifier in a data repository;

in which the royalty payment action is initiated when a rendering device decodes the steganographic embedding and obtains the identifier during a transaction, the identifier being provided to the data repository and, in response to receiving the identifier, performing the royalty payment action, in which said performing the royalty payment action does not occur when the content includes limited functionality for initial evaluation prior to a purchase or licensing transaction but said performing the royalty payment action does occur when the content is purchased or enabled for longer evaluation relative to the initial evaluation;

wherein the royalty payment action comprises determining a percentage of revenue that corresponds to an amount of times the content undergoes a transaction.

2. The method of claim 1 wherein the network comprises a peer-to-peer file-sharing network.

3. A non-transitory computer readable medium comprising instructions stored thereon to cause one or more electronic processors to perform the method of claim 1.

4. A non-transitory computer readable medium comprising instructions stored thereon to cause one or more electronic processors to perform the method of claim 2.

8. A programmed computing system storing instructions in memory, said instructions are executable by said programmed computing system to perform the acts of claim 1.

5. A method comprising:

receiving registration information corresponding to audio or video content prior to distribution of the audio or video content;

assigning an identifier to the audio or video content or to a participant associated with the audio or video content;

utilizing an electronic processor configured to embed the identifier in the audio or video content with digital watermarking, wherein the digital watermarking alters data representing the audio elements or video picture elements of the audio or video content to hide the identifier therein;

maintaining the identifier in a data repository;

distributing embedded audio or video content;

and determining revenue attributable to an amount of times the audio or video content undergoes a transaction by utilizing at least the identifier, in which said determining does not occur with content having limited functionality for initial evaluation prior to a purchase or licensing transaction but said determining does occur with content purchased or enabled for longer evaluation relative to the initial evaluation;

wherein said act of determining determines a percentage of revenue that is attributable to an amount of times the audio or video content undergoes a transaction by utilizing at least the identifier.

6. A non-transitory computer readable medium comprising instructions stored thereon to cause one or more electronic processors to perform the method of claim 5.

7. A non-transitory computer readable medium comprising instructions stored thereon to cause one or more electronic processors to perform the method of claim 5.

9. A programmed computing system storing instructions in memory, said instructions are executable by said programmed computing system to perform the acts of claim 5.

10. An apparatus comprising:

electronic memory for buffering registration information from a participant who requires royalty payments for content to be distributed;

and an electronic processor programmed for;

assigning a unique identifier to the participant;

steganographically embedding the content with the unique identifier; and

associating a royalty payment action with the identifier in a data repository, in which the royalty payment action is initiated when a rendering device decodes the steganographic embedding and obtains the identifier during a transaction, the identifier being provided via a network to the data repository, and,

in response to receiving the identifier, performing the royalty payment action, and in which said performing the royalty payment action does not occur when the content includes limited functionality for initial evaluation prior to a purchase or licensing transaction but said royalty payment action does occur when the content is purchased or enabled for longer evaluation relative to the initial evaluation;

in which the royalty payment action comprises determining a percentage of revenue that corresponds to an amount of times the content undergoes a transaction.

11. The apparatus of claim 10 wherein the network comprises a peer-to-peer file-sharing network.

12. The apparatus of claim 10 in which said electronic processor is operating to perform at least one of the functions recited therein.

13. An apparatus comprising:

electronic memory for buffering registration information corresponding to audio or video content prior to distribution of the audio or video content; and

an electronic processor programmed for;

assigning an identifier to the audio or video content or to a participant associated with the audio or video content;

embedding the identifier in the audio or video content with digital watermarking, in which the digital watermarking alters data representing audio elements or video picture elements of the audio or video content to hide the identifier therein;

maintaining the identifier in a data repository;

distributing embedded audio or video content; and

determining revenue attributable to an amount of times the audio or video content undergoes a transaction by utilizing at least the identifier, in which the determining does not occur with content having limited functionality for initial evaluation prior to a purchase or licensing transaction but the determining does occur with content purchased or enabled for longer evaluation relative to the initial evaluation;

in which said determining determines a percentage of revenue that is attributable to an amount of times the audio or video content undergoes a transaction by utilizing at least the identifier.

14. The apparatus of claim 13 in which said electronic processor is operating to perform at least one of the functions recited therein.
