1. A method of controlling access to a document file, comprising:
creating the document file, wherein the document file is a processor-readable file that includes content having at least one media type, wherein the content is presentable to a user on an electronic device having a processor;
encrypting the document file; and
providing the encrypted document file to the user, including making the encrypted document file available to be stored on a content storage device configured to interface for communication with the processor, wherein the content storage device is associated with a unique global identifier and is arranged internal to the electronic device or external to the electronic device;
wherein encrypting the document file includes applying an encryption algorithm to the document file to reversibly encipher the document file; and
wherein applying the encryption algorithm to the document file includes providing an encryption key and the unique global identifier and actuating the encryption algorithm with the encryption key and the unique global identifier.
