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.
A method of controlling access to digital media, residing on a first computer system, destined for playback, storage, or re-transmittal to another computer system, by generating a private encryption key on the first computer system for the purpose of encrypting and decrypting said digital media content through the use of a standard encryption key generating algorithm and a seed, where said seed is obtained from the identifying information of the second computer system.
The encryption key of claim 6, where the seed is further derived from the identification information of the second computer system.
Dependencies are inferred from the claim text.
