    摘要: There is provided a system and method for distributors to use an interoperable key chest. There is provided a method for use by a distributor to obtain content access authorizations from a key chest or central key repository (CKR), the method comprising receiving a user request from a user device for access to an encrypted content identified by a content identification, transmitting a key request to the CKR including the content identification, receiving an encrypted first key from the CKR, decrypting the encrypted first key using a second key to retrieve the first key, and providing a DRM license for the encrypted content to the user device using the first key for use by the user device to decrypt the encrypted content using the first key. By generating such DRM licenses, distributors can unlock protected content even sourced from distributors using different DRM schemas.

    摘要: There is provided a system and method for a universal file packager for use with an interoperable key chest. There is provided a method for distributing media contents to distributors, comprising obtaining a first key, a second key and a content, encrypting the second key using the first key to generate an encrypted second key, encrypting the content using the second key to generate an encrypted content, generating a key information file including the encrypted second key, generating a universal file including the encrypted content and a first network address for a central key repository (CKR), providing the key information file for storage in the CKR, and providing the universal file to the distributors. The universal file can then be provided to users for digital e-commerce and transferred across different distributors with the CKR negotiating key access for granting new interoperable DRM licenses.

    摘要: 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.

    摘要: A system and method is provided for identifying electronic devices belonging to the same authenticated user to allow access to shared media even if the electronic devices use incompatible digital rights management (DRM) schemes. By providing a method of registering electronic devices in a centralized rights server database, a user can acquire DRM licenses for the appropriate electronic device by simply registering the electronic devices. When the user later requests a DRM license, it only needs to provide cryptographic proof of a UID, or unique identifier, assigned to the device by the rights server. In this manner, media can he shared across devices Using incompatible DRM schemes.

    摘要: There is presented a system and method for updating digital media content. The system comprises a data structure residing on a media storage, the digital media content being stored in the data structure. The system further comprises a processor coupled to the media storage and configured to access the data structure, and receive an update to one or more modifiable elements of the data structure from an authoritative source external with respect to the data structure. The processor is further configured to modify the modifiable elements according to the update, and store the modified elements in the data structure. As a result, updates to the modifiable elements are persistently stored in the data structure.
