Abstract: Systems and methods are disclosed that authenticate devices or users, and enable playback of secured streaming content through a media player. In one embodiment, the invention is a system for receiving secure content over an unmanaged network, including a security application configured operate on a user device with access to a network, where the security application is configured to receive a request for playlist data from the media player, send a playlist request to a content server, receive playlist data from the content server, send playlist data to a media player, receive a security access request from the media player, send a security access request to a security server, receive security access data from the security server; and send security access data to a media player.

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.

Abstract: Systems and methods are described for over-encrypting symmetrically pre-encrypted content for off-line delivery to playback devices using portable media drives in accordance with embodiments of the invention. One embodiment of the method of the invention includes symmetrically pre-encrypting the content, receiving a request to issue content for playback on at least one playback device associated with a user account, where each playback device includes a processor containing a private key assigned to the playback device by a conditional access system, generating a content key and over-encrypting at least a portion of the symmetrically pre-encrypted content in response to the request, obtaining a public key for each playback device, encrypting a copy of the content key using the public key of each playback device associated with the user account, and delivering the over-encrypted content and the at least one encrypted copy of the content key to a playback device associated with the user account.
