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.

Claims (6)

1. A method to selectively encrypt streaming media data, comprising:

selectively encrypting a portion of media data, wherein the media data includes video and audio data, and wherein an encryption technique being used and the portion of the media data being encrypted are represented as encryption settings that are received from a content provider associated with the media data encrypted, wherein the media data is divided into a configurable number of byte chunks of a configurable size, and wherein the non-contiguous pieces include a configurable number of bytes within each chunk; and

streaming the portion of media data encrypted and the media data to one or more recipients located over a network, and wherein to use any portion of the media data the one or more recipients have to decrypt the portion that is encrypted.

2. The method of claim 1 wherein in selectively encrypting, the portion includes a predefined percentage of the media data.

3. The method of claim 2 wherein in selectively encrypting, the predefined percentage is configurable.

4. The method of claim 1 wherein in selectively encrypting, the portion includes non-contiguous pieces of data included within the media data.
