SYSTEMS AND METHODS FOR SECURELY STREAMING MEDIA CONTENT

摘要

Systems and methods securely provide media content from a media server to a media client via a network. The media content is segmented to create multiple media segments that are each identified in a playlist, and at least one of the media segments is encrypted using a cryptographic key. The cryptographic key is also identified in the playlist, and the playlist is provided from the media server to the media client via the network. The various media segments and cryptographic keys may then be requested from and provided by the media server using hypertext transport protocol (HTTP) or similar constructs to allow the media client to receive and decrypt the various segments of the media content.

1. A method to securely provide a stream of media content from a media server to a media client via a network, the method comprising:
segmenting the media content to thereby create a plurality of media segments that are each identified in a playlist, encrypting at least one of the media segments using a cryptographic key, wherein the cryptographic key is identified in the playlist, receiving an authentication credential at the media server, wherein the authentication credential is generated by account server that is separate from the media server; in response to a successful verification of the authentication credential, providing the playlist from the media server to the media client via the network; and in response to subsequent requests that are received from the media client via the network, providing the requested media segments and the cryptographic key from the media server via the network to thereby provide the media stream to the media client.
