Abstract
Techniques for thwarting piracy of real-time content such as broadcast streams are described. In one technique, when portions of a real-time content is received at a user device, the device embeds a particular code in the received content that associates the real-time content to that user device. When further portions of the real-time content that has one or more codes is received at the user device, the device determines if the particular code matches the one or more codes that are incorporated into the real-time content, and if a match if found, one of more actions is initiated at the user device to thwart further dissemination of the real-time content. The initiated actions can interfere with the playback of the real-time content or provide warning messages, and thus eliminate or discourage the use of the user device as a source of real-time content piracy.
