    摘要: A stream of content has multiple sub-streams, where each sub-stream comprises a part of the content and is divisible into logical blocks bounded by intrinsic partitions. For each sub-stream, a specification of the logical blocks bounded by the intrinsic partitions is defined and the sub-stream is divided into the logical blocks bounded by the intrinsic partitions. Each divided logical block is encrypted and then divided into one or more portions to produce corresponding pieces of data, and each piece of data is placed into a data packet as a payload thereof. Each data packet is transmitted to a recipient thereof, and the recipient can retrieve the pieces of data from the payloads of the packets, reconstruct the encrypted logical blocks, and manipulate the sub-stream on a per-logical block basis without necessarily decrypting each encrypted logical block.

    摘要: Systems and/or methods (“tools”) are described that enable encrypted media files to be sent without revocation lists while permitting the encrypted media files to be passed to trusted entities. The tools may also ensure continuation of protection when media files are passed between different protection systems.

    摘要: Systems and methods to license combinations of one or more data streams from an encoded file including multiple data streams are described. In one aspect, the encoded file is accessed from a data source. A header is generated to specify a first group of one or more data streams for licensing independent of a second group of one or more data streams. The data stream content in the first group is not equivalent to the data stream content of the second group. A number of business rules are identified to indicate respective licensing strategies for the data streams in the first and second groups. A data file is generated to encapsulate the header and an encrypted version of the encoded media. An end-user is provided access to the data streams in the first and/or second groups via the data file and the header according to the respective licensing strategies.

    摘要: A sink sends a registration request to a source and the source validates same, and the source sends a registration response including a secret to the sink. The source then sends a proximity message including a nonce to the sink and concurrently notes a start time. The sink employs the secret and the nonce to generate a proximity value and sends same to the sources. The source receives the proximity value and concurrently notes an end time, verifies the proximity value based on the secret and the nonce, calculates from the noted start and end times an elapsed time, compares the elapsed time to a predetermined threshold value, decides from the comparison whether the sink satisfies the proximity requirement, and registers the sink as being able to access content from such source if the sink satisfies the proximity requirement.

    摘要: This document describes tools capable of managing digital content from multiple content providers based on a user's identity. By so doing, the tools may free people from the limitations of their storage media and devices. The tools may perform these and other actions through an indirect relationship with users, such as when third-party content providers use the tools but provide their own direct interface with users.

    摘要: This document describes tools capable of securely distributing entertainment content among and using distributed hardware. These tools may do so robustly by rebinding entertainment content between distributed hardware units. The tools, for example, may distribute content protection in hardware between a policy unit, a transcryption unit, a graphics processing unit, and a playback unit. By so doing the tools enable, among other things, users to select from many graphics cards rather than rely on the graphics capabilities of an integrated (e.g., SOC) hardware solution.
