ABSTRACT:
A method of controlling presentation of content on a media storage device is described. The method is comprised of verifying the presence of a media presentation mechanism and a usage compliance mechanism on a computer system operated by a recipient to whom the media storage device is distributed. The usage compliance mechanism includes a file system filter driver for controlling data reads associated with the computer readable media. The media presentation mechanism is communicatively coupled with the usage compliance mechanism. The present method further includes the file system driver performing a first decryption of the computer readable media. The present method further includes the media presentation mechanism performing a second decrypting of the computer readable media concurrent with presenting the computer readable media to the recipient.
