Abstract
Methods and apparatus for preventing unauthorized access to online content, including in particular streaming video and other media, are provided. In various embodiments, techniques are provided to authorize users and to authenticate clients (e.g., client media players) to a content delivery system. The content delivery system may comprise a content delivery network with one or more content or “edge” servers therein. The requesting client is sent a program at the time of content delivery. The program may be embedded in the content stream, or sent outside of the stream. The program contains instructions that are executed by the client and cause it to return identifying information to the content delivery system, which can then determine whether the client player is recognized and, if so, authorized to view the content. Unrecognized and/or altered players may be prevented from viewing the content.
