Abstract
There is provided a system and method for an interoperable keychest. There is provided a method for use by a central key repository (CKR) or keychest to provide content access authorizations to distributors, comprising receiving a key information file including a first encrypted second key for decrypting with a first key and a content identification, decrypting the first encrypted second key using a first key to retrieve the second key, receiving, from a distributor, a key request including the content identification, encrypting the second key using a third key to generate a second encrypted second key, and transmitting the second encrypted second key to the distributor in response to the receiving of the key request. In this manner, key management for protected distributors using different DRM schemas or systems may be simplified and made interoperable.
Background
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to digital media. More particularly, the present invention relates to digital rights management for digital media.2. Background Art
Although digital media distribution is growing in popularity and becoming a viable alternative to purchasing retail physical media for many consumers, there are still significant barriers present before consumers can wholly embrace digital media without reservations. Many of these reservations revolve around the limited interoperability between different playback devices or service providers, and the possibility that media files may become inoperable in the future due to new formats or protection schemes. For example, competing digital media distribution channels may use incompatible media formats and proprietary DRM systems, and the closing or termination of video offerings due to financial difficulties or company ownership changes may leave consumers with media files that cannot be consumed anymore.
Thus, there is a need for interoperable protected contents that can survive changes in the distribution market and provide continued service to consumers regardless of the original distribution channel used and the original media file format. In this manner, consumers can easily switch service providers, use protected media across a wide variety of playback devices, and remain confident that playback of protected content is ensured into the
Claims
29. A method for use by a repository having a memory and a processor to provide access to media contents, the method comprising: receiving, using the processor of the repository, a first digital receipt issued by a first distributor granting a first consumer a right to access a first media content; registering the first digital receipt in the memory of the repository, using the processor of the repository, wherein the registering of the first digital receipt includes associating the first media content and the first consumer; receiving, using the processor of the repository and after the registering of the first digital receipt, a request from a second distributor to determine rights of the first consumer, wherein the request identifies the first consumer and the second distributor is different than the first distributor; determining, using the processor of the repository, that the first consumer has the right to access the first media content based on the registering and in response to the request; and providing, using the processor of the repository, the second distributor with a response based on the determining that the first consumer has the right to access the first media content, in response to the request.
39. A repository for providing access to media contents, the repository comprising: a memory; and a processor configured to: receive a first digital receipt issued by a first distributor granting a first consumer a right to access a first media content; register the first digital receipt in the memory of the repository, wherein registering the first digital receipt includes associating the first media content and the first consumer; receive, using the processor of the repository and after the registering of the first digital receipt, a request from a second distributor to determine rights of the first consumer, wherein the request identifies the first consumer and the second distributor is different than the first distributor; determine, using the processor of the repository, that the first consumer has the right to access the first media content based on the registering and in response to the request; and provide, using the processor of the repository, the second distributor with a response based on the determining that the first consumer has the right to access the first media content, in response to the request.
48. A method for use by a repository having a memory and a processor to provide access to media contents, the method comprising: receiving, using the processor of the repository, a first digital receipt issued by a first distributor granting a first consumer a right to access a first media content; registering the first digital receipt in the memory of the repository, using the processor of the repository, wherein the registering of the first digital receipt includes associating the first media content and the first consumer; determining, using the processor of the repository and after the registering, that the first consumer has the right to access the first media content based on the registering; and communicating with a second distributor, using the processor of the repository, that the first consumer has the right to access the first media content, in response to the determining that the first consumer has the right to access the first media content.
