Abstract

A digital rights network (10) includes a digital rights server (36) to store content consumer rights, defining access right of a content consumer with respect to content, and content owner rights defining access policies to the content as established by a content owner. A digital rights agent (28) is to perform cryptographic operations with respect to access operations relating to the content consumer rights and the content owner rights. The access operations include a first access operation with respect to the content consumer rights and a second access operation with respect to the content owner rights. The access operations relating to the content consumer rights and the content owner rights may be performed by anyone of a plurality of users of the digital rights network such as the content owner, a commerce service provider (42), a content distributor (20) and the content consumer. The commerce service provider (42) may be a customer relationship management operator.

16. The digital rights network of claim 1 wherein the content consumer rights are acquired from a content distributor with which the content consumer has a relationship.

17. The digital rights network of claim 1 wherein the content consumer rights are acquired from a plurality of network operators.

18. The digital rights network of claim 1 wherein a certificate is associated with the content consumer, and wherein the content consumer rights, acquired from the plurality of network operators, are attributed to the content consumer utilizing the certificate.

19. The digital rights network of claim 1 wherein the first access operation is to register the content consumer and is performed by a network operator, the digital rights agent to verify that the network operator is authorized to perform the first access operation.

20. The digital rights network of claim 1 wherein the first access operation is to register the content consumer rights, and the digital rights agent is to encrypt and sign the content consumer rights prior to storage thereof by the digital rights server.

21. The digital rights network of claim 1 wherein the first access operation is by the content consumer and is to create a license to the content, wherein the digital rights agent is to create the license.

22. The digital rights network of claim 1 wherein the first access operation is by the content consumer to validate access to the content, and the digital rights agent is to perform the validating action.

23. The digital rights network of claim 1 wherein the digital rights server comprises a content server to store the content owner rights and a user server to store the content consumer rights.

24. A method of operating a digital rights network, the method including:

storing content consumer rights, defining access rights of a content consumer with respect to content, and content owner rights defining access policies to the content as established by a content owner at the digital rights server; and

performing cryptographic operations, utilizing a digital rights agent, with respect to access operations relating to the content consumer rights and the content owner rights,

wherein the access operations include a first access operation with respect to the content consumer rights and a second access operation with respect to the content owner rights.

25. The method of claim 24 the access operations relating to the content consumer rights and the content owner rights are performed by any one of a plurality of users of the digital rights network.
