METHOD AND APPARATUS FOR NETWORKED INFORMATION DISSEMINATION THROUGH SECURE TRANSCODING

摘要

The method and system allows a network intermediaries such as proxy can transcode multimedia data does not violate the security guarantees between both ends. In one embodiment, the content provider is to decompose the data stream into a plurality of components, each component is encrypted independently. In a preferred embodiment, the mediator that is proxy transcoding of the components eliminated by prioritizing of certain components in accordance with the ordinary non-encrypted statement text metadata associated with, each of the components without the need to decode the components. Usually the door text metadata is preferably provided by an absolute or a semantic understanding of the relative importance / priority of the components with respect to each other, the more readily the transcoding process. Destination / client device decrypting the ring component transmitted by the transcoding proxy, and subsequently re-assemble them in the representation of the original data content.; Transcoding, security, multimedia content, proxy, encoding, decoding,
