ABSTRACT:
Methods, systems, and data structures are provided selectively encrypting portions of media data that are streamed over a network. Media data is identified and a portion of the data is selectively encrypted. The media data is then streamed over a network to one or more recipients for consumption. The intended recipients cannot consume the media data until the encrypted portion is properly decrypted.
