Abstract

Systems and methods for controlling the use and duplication of digital content distributed on removable media are described. In accordance with embodiments of the present invention digital content is protected by allowing a particular number of protected (e.g., encrypted) copies of the digital content to be made. Typically, these copies may only be used on and moved between authorized devices. In one embodiment, if copies are desired, the maximum number of allowable copies of the protected digital content are made and stored on a computer's hard drive when the storage medium (e.g., a CD) containing the content is inserted into the computer. Each copy can then be moved but not copied to other devices (e.g., portable solid state devices). In an alternative embodiment, the storage medium containing the digital content is writable (e.g., a CD-R). When the storage medium is inserted into the computer, the computer writes information to the storage medium which regulates future copying and playing of the digital content on the storage medium.
