摘要： An example method for managing digital rights management (DRM) protected content sharing in a networked secure collaborative computer data exchange environment includes establishing, by a secure exchange facility and managed by an intermediate organizational entity, a procedure that allows a user from a first entity to share access to computer data content with a user from a second entity based on indicated access rights. The method includes transforming the computer data content into DRM protected content, utilizing a DRM engine provided by a separate entity. The method includes granting access to the content to the second user, providing permissioned control to entities utilizing a number of data storage nodes, and managing secure data exchange of the content and metadata, without the secure exchange facility having access to the content. The method includes operations to support content services including data transformation, filtering, analytics, and searching tools for the content.

摘要： A digital rights management system includes two digital rights management servers (RMS servers) connected to a client computer. The two RMS servers implement different but related digital rights management (DRM) policies, with the first RMS server implementing conventional DRM policies and the second RMS server implementing extended DRM policies. An application program on the client computer interacts with a document on the client computer, and communicates with the first RMS server to obtain access authorization for the document. A plug-in program in the client computer cooperates with the application program, and communicates with the second RMS server to obtain additional access authorization for the document. Access to the document is granted when both RMS servers grant access to the document. This achieves extended digital rights management control which can provide a more flexible access control than that provided by existing DRM systems.

摘要： Supporting a plurality of content protection systems in a single container file. The protection systems share an encryption method which is accessible from a sample encryption box in the file. Each of the protection systems stores, in a protection system header box, information for decrypting the content in accordance with the corresponding protection system. In some embodiments, separate protection system header boxes in the file correspond to each of the protection systems. By using the common encryption method and sharing encryption expressions across the protection systems, the multiple content protection systems are supported in the file without creating additional copies of the content. In some embodiments, aspects of the disclosure extend the International Organization for Standardization (ISO) base media file format to support multiple digital rights management (DRM) systems in the single container file.

摘要： There is provided a system and method for a digital receipt for use with an interoperable keychest. There is provided a method for online registration of a digital receipt associated with a content, comprising performing a transaction to obtain from a first distributor the content encrypted by a title key and a first digital rights management (DRM) license usable with the first distributor to access the title key, receiving from the first distributor the digital receipt associated with the content including information relevant to the transaction, and transmitting the digital receipt to the interoperable keychest acting as a central key repository (CKR) for an online registration of the digital receipt associated with the content. Authorized media distributors may then generate new DRM licenses using the CKR, enabling interoperable content playback of the same universal file across different media distributors and clients.

摘要： A DRM server parses a request received from a client for a content identifier and client classification information. The content identifier identifies the requested content and client classification information describes the capabilities of the client. The DRM server determines a policy for the requested content. The policy specifies rules for determining access rights for the content responsive to the capabilities of the client. The DRM server determines access rights for the requested content responsive to the capabilities of the client and the policy. The DRM manager then provides the requested content and the determined access rights to the client.

摘要： In a method for communicating media content stored on a digital video recorder (DVR) protected by a first DRM system to a portable multimedia device (PMD) using a second DRM system, in which the first DRM system differs from the second DRM system, a request for communication of a media content item stored on the DVR to the PMD is received. In addition, a portable content key is employed to encrypt the media content item to a PMD format suitable content version and the encrypted PMD format suitable content version is communicated to the PMD along with a portable content identifier (ID).
