Abstract

A license server and corresponding method are provided for managing the rights of content as it is propagates through a social network. A license server receives a distribution package from a content producer and establishes a plurality of level-licenses, one for each of n allowable levels as defined by the content producer. Level-licenses define level-rights, or access rules, based on alteration definitions and other distribution parameters provided by the content producer for each allowable level. Alteration definitions may identify degradation characteristics or augmentation files for association with the distributed digital content. Content recipients who receive encrypted copies of the distributed digital content may request a license from the license server. Upon authentication, a license and decryption key is sent to a valid content recipient to enable viewing of a form of the digital content in accordance with the level-rights predetermined by the content producer for that level of access.

Claims

1. A method of configuring and managing user rights to distributed digital content, comprising the following steps:

generating, by a license server, a level-license for each of a plurality of levels associated with a distribution of at least one digital content, wherein each level-license defines access rights to the at least one digital content by a content recipient associated with a respective level of the plurality of levels;

receiving, by the license server, a request from a respective content recipient for access to a form of the at least one digital content;

determining a distribution path of the at least one digital content from an originating node to the respective content recipient;

determining, by the license server, a respective level of the plurality of levels associated with the respective content recipient based on a number of content recipients of the digital content in the distribution path of the digital content from the originating node to the respective content recipient; and

sending, by the license server, one of the level-licenses to the respective content recipient granting access rights in accordance with the respective level of the plurality of levels associated with the respective content recipient, wherein access to the at least one digital content is prevented beyond a predefined level of the plurality of levels.

2. The method of claim 1, further comprising a step of receiving a content distribution package, wherein the content distribution package comprises the at least one digital content, a unique key ID for identifying the distribution package, and a license key seed.

3. The method of claim 2, wherein the received distribution package further comprises a configuration data file with distribution parameters including a level number identifying a number n of allowable levels and at least one alteration definition for one or more of the n allowable levels.

4. The method of claim 3, wherein each alteration definition identifies one or more of a degradation characteristic for applying to the at least one digital content and an augmentation file for adding to the at least one digital content.

5. The method of claim 1, further comprising a step before said sending step of authenticating the respective content recipient.

6. The method of claim 5, wherein said authenticating step comprises verifying that the respective content recipient was named in a distribution list for a user at a preceding level in a social network.

7. The method of claim 1, further comprising a step of registering the respective content recipient.

8. The method of claim 1, wherein the level-license from said sending step includes a key used to decrypt the respective content recipient'"'"'s version of received digital content and to provide access in accordance with the respective content recipient'"'"'s level-license.

9. The method of claim 1, further comprising a step of sending notification to a content producer each time another user views or distributes the form of the at least one digital content in a social network.

10. The method of claim 1, further comprising a step of modifying the level-licenses from said generating step upon a subsequent request from a user.

11. A license server for configuring and managing user rights to distributed digital content, comprising:

a processor unit; and

at least one portion of computer-readable medium for storing program code that is read and executed by said processor unit, said processor unit and said at least one portion of computer-readable medium functioning together to provide a plurality of operative modules, said modules comprising;

a. a level-license creation module configured to establish a level-license for each of a plurality of levels associated with a distribution of at least one digital content, wherein each level-license defines access rights to the at least one digital content by a respective content recipient associated with a respective level of the plurality of levels;

b. an authentication module for determining a distribution path of the at least one digital content from an originating node to the respective content recipient;

c. the authentication module for determining a respective level of the plurality of levels associated with the respective content recipient based on a number of content recipients of the digital content in the distribution path of the digital content from the originating node to the respective content recipient and for verifying that each requesting user is an intended recipient of the at least one digital content, wherein access to the at least one digital content is prevented beyond a predefined level of the plurality of levels;

d. and a license assignment module for granting licenses to authenticated users who request access to the at least one digital content.

12. The license server of claim 11, further comprising a communications interface for coupling the license server to a network.

13. The license server of claim 12, wherein said license server is configured to receive input via said communications interface from one or more users, including content producers and the content recipients, and wherein the level-license creation module establishes level-licenses based on distribution parameters provided from a content producer.

14. The license server of claim 11, wherein said operative modules further comprise a registration module for verifying that a user has obtained access to a required desktop application.

15. The license server of claim 11, wherein said license assignment module is further configured to block or revoke licenses to selected users based on input received from a content producer.

16. An article of manufacture comprising a computer-readable medium embodying program instructions for directing a computing device to:

create a plurality of level-licenses from distribution parameters obtained from a content producer, wherein each level-license defines level-rights to digital content for one of a plurality of levels associated with a distribution of the digital content in a social network;

determine a distribution path of the digital content from an originating node to a respective content recipient; and

upon request from the respective content recipient, determine a respective level of the plurality of levels associated with the respective content recipient based on a number of content recipients of the digital content in distribution path of the digital content from the originating node to the respective content recipient and sending a license to the respective content recipient, wherein the license includes a key for decrypting the digital content in accordance with the level-rights defined by the content producer for the particular level associated with the respective content recipient, and wherein access to the digital content is prevented beyond a predefined level of the plurality of levels.

17. The article of manufacture of claim 16, wherein the level-rights include one or more of a degradation characteristic for applying to the digital content and an augmentation file for adding to the digital content.

18. The article of manufacture of claim 16, wherein the computer-readable medium includes additional program instructions for further directing a computing device to verify the authenticity of the respective content recipient before sending a license to the respective content recipient.

19. The article of manufacture of claim 16, wherein the computer-readable medium includes additional program instructions for further directing a computing device to deny access to the digital content to levels in the social network beyond a predefined level limit of n levels.

20. The article of manufacture of claim 16, wherein the computer-readable medium includes additional program instructions for further directing a computing device to send notification to the content producer each time another user views or distributes a form of the digital content in the social network.
