PROTECTING DIGITAL MEDIA OF VARIOUS CONTENT TYPES |
摘要 |
Systems and/or methods ("tools") are described that enable a digital rights management policy to be associated with digital media having an arbitrary content type or transfer control protocol. In some embodiments, the tools encrypt data segments of a media file and add a descriptor to each of those segments. These descriptors can enable a receiver of the encrypted media file to decrypt the file and consume it according to the correct digital rights management policy. |
