Techniques for automated suggestions for cross-context digital item containers and collaboration are provided, including analyzing digital items in each of multiple portfolios of digital items in order to determine similarities among the portfolios. The techniques proceed by determining similar portfolios for a first portfolio of digital items, and suggesting changes (e.g., additions, deletions, or alterations of digital items) based on differences between the first portfolio and the similar ones. Those changes can be accepted or rejected and applied to the first portfolio of digital items.

Automated suggestions in cross-context digital item containers and collaboration

Techniques for synchronization for cross-context digital item containers and collaboration are provided, receiving a user command to share a particular digital item from a first portfolio of digital items with a second portfolio of digital items. In response receiving the command to share the digital item, making a digital copy of it and placing it in the second portfolio of digital items. Subsequently, an alteration is made to the digital item and a determination is made with whom to share the alteration among those with whom the digital item had been previously shared. Those alterations can be accepted (or rejected) by the other portfolios. When they are accepted, they are applied to the digital copy.

Synchronization for cross-context digital item containers and collaboration

Techniques for cross-context digital item containers and collaboration are provided, including receiving a command to add a particular digital item in a portfolio of digital items, wherein the portfolio of digital items includes one or more digital items, and then adding it in the portfolio of digital items. Subsequently, a request for display of the portfolio of digital items is received and an interactive view of the portfolio of digital items, including the particular digital item is displayed. When an interaction with the interactive view of the portfolio of digital items requesting to use the particular digital item in a second application is received, a digital copy of the particular digital item is provided to the second application for use in the second application.

A method and system for attaching a title key to encrypted content for synchronized transmission to, or storage by, a recipient is provided. Specifically, under the present invention, an elementary media stream is parceled into content units that each include a content packet and a header. The content packets are encrypted with one or more title keys. Once the content packets have been encrypted, the title keys are themselves encrypted with a key encrypting key. The encrypted title keys are then attached to the corresponding encrypted content packets for synchronized transmission to a recipient.

Various embodiments of a system and method for digital rights management with secure application-content binding are described. Various embodiments may include a system configured to decrypt an encrypted application key with a private key. The system may also be configured to decrypt an encrypted application including a binding key with the decrypted application key. The system may also be configured to decrypt an encrypted content key with the binding key from the decrypted application. The system may be further configured to decrypt encrypted content with the decrypted content key. In various embodiments, the system may also be configured to consume the decrypted content with the decrypted application.

System and method for digital rights management with secure application-content binding

Embodiments may include a content provider system configured to provide electronic content that includes multiple encrypted content items to a playback device. A playback device may be configured to acquire root licenses and/or content licenses from a license server; such licenses may cryptographically protect the content items that a playback device receives from a content provider system. In various embodiments, the electronic content may be content that is to be linearly consumed, such as a channel within a broadcast environment. In various embodiments, the playback device may explicitly request a license for one or more of the content items that it receives; such request may be issued to a license server. The license server may evaluate the request and respond to the playback device with the license for a content item. In various embodiments, the playback device may utilize the received license to decrypt and consume the respective content item.

System and method for providing content protection of linearly consumed content with a bidirectional protocol for license acquisition

The present invention provides a method, system and program product for modifying content usage conditions during broadcast content distribution. Specifically, the present invention allows protected (e.g., encrypted, secured, etc.) content to be received along with content usage conditions, an encrypted combination of the content usage conditions and a title key (e.g., a MAC), and a key management block. Using the key management block, a key encrypting key can be determined for decrypting the combination. Once the combination is decrypted, the content usage conditions can be modified (e.g., edited, added to, etc.).

Method, system and program product for modifying content usage conditions during content distribution

Various embodiments of a system and method of digital rights management with authorized device groups are described. Various embodiments may include a system including a digital rights management (DRM) component configured to receive a private key of an authorized device group. In various embodiments, the receipt of the private key of the authorized device group may indicate the system is an authorized member of a group of devices permitted to access content items protected by a common public key associated with the authorized device group. In various embodiments the DRM component may be configured to, for each given content item of multiple content items that are encrypted with different content keys, decrypt an encrypted content key from the given content item with the private key of the authorized device group and decrypt content from the given content item with the decrypted content key.

System and method for digital rights management with authorized device groups

In accordance with the domain management for digital media, a device obtains multiple pieces of protected content from multiple content providers, where two or more of the content providers employ different digital rights management systems. The device also accesses a license server to obtain, for each piece of protected content, a content license that is bound to a domain. The content license permits the device to play back a piece of protected content.

Domain management for digital media

Interoperability of protected content items between computing devices is facilitated by providing content items having a standard representation, and media players having support for the content item representations. The representation of the content item may be limited by a profile as to the elements it contains. The elements allowed in the content item may also be limited.

Content protection interoperability infrastructure

Enhanced multimedia content on physical media interacts with the user through a media player and the Internet. Enhanced multimedia utilizes IDs for pieces of content on the media and a media key block. On the enhanced media is a file with a list of URLs. As the enhanced media plays a title requiring an external permission for decryption, the media player accesses the URL for that title and obtains the permission. The permission may be purchased or provided for free. Secure encryption and transmission of permission is accomplished by broadcast encryption using a media key block. Each media has a unique set of keys that allow the media player to process the media key block; however, each media follows a unique path through the media key block. All legitimate media players obtain the media key; circumvention devices cannot decipher the media key block.

System, method, and service for delivering multimedia content by means of a permission to decrypt titles on a physical media

In accordance with the domain management for digital media, a device accesses a domain administrator in order to obtain a domain membership license. The domain membership license indicates that the device is part of a domain that includes multiple devices associated with a user of the device. The device also obtains multiple pieces of protected content from multiple content providers, with two or more of the multiple content providers employing different digital rights management systems. The device also accesses a license server to obtain, for each piece of protected content, a content license that is bound to the domain. The content license permits the device to play back the piece of content to the user.

Enhanced multimedia content on physical media interacts with the user through a media player and the Internet. Enhanced multimedia utilizes IDs for pieces of content on the media and a media key block. On the enhanced media is a file with a list of URLs. As the enhanced media plays a section requiring a set of keys for decryption, the media player accesses the URL for that section and obtains the decryption key. The decryption key may be purchased or provided for free. Secure encryption and transmission of these keys is accomplished by broadcast encryption using a media key block. Each media has a unique set of keys that allow the media player to process the media key block; however, each media follows a unique path through the media key block. All legitimate media players obtain the media key; circumvention devices cannot decipher the media key block.
