Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for securely publishing and accessing a media's premium content. Methods include a media that comprises premium content encrypted with a first cryptographic key. The media also comprises data structures that include this key and the access entitlements. These data structures are encrypted using the key for each entity that can authorize user access to the media. Methods further include verifying user access to the media and then providing the decrypted premium content. Methods include decrypting the data structure using the authorizing entity's key and providing the first cryptographic key in the decrypted data structure to the client device, after verifying that the user has the appropriate access entitlements for the media. Methods include decrypting the premium content using the first cryptographic key and then displaying the media, including the decrypted premium content, on the client device.
