Abstract
The instant invention relates to a method and apparatus for restricting access to digital content through the use of an exemplary form of digital encryption which ties the delivered content to a user, a specific destination device, a specific network, or one or more of the above. Specifically, the encryption/decryption keys are unique in each content consumption session, whether download or stream, which permits the content owner to provide multiple levels of access, i.e. different users may purchase different levels of access to the same content. For example, one user might want to use content on multiple playback devices, while another user might only need access on a single playback device.
