First Claim
1. A method to delivery encrypted digital content to a system for playing the content comprising the steps of:
- reading from a computer readable medium metadata which has previously associated with the content;
selecting from the metadata associated content to decrypt;
establishing a secure transmission with an authorization authority for decrypting the content;
receiving a decrypting key for decrypting at least part of the previously encrypted content stored on the computer readable medium as permitted.

Abstract
A method to delivery encrypted digital content to a end user system for playing the content comprising the steps of: reading from a computer readable medium metadata which has previously associated with the content. A user selects from the metadata associated content to decrypt and the end user system establishes a secure connection with an authorization authority for decrypting the content. The end user system receives a secure container containing the decrypting key for decrypting at least part of the previously encrypted content as permitted. The system creates a secure container using the encrypting key from a clearing house, wherein the secure container has an encrypting key therein from the end user system; transferring the secure container to the clearing house for authentication of permission to decrypt the content. The system receives from the clearing house, a secure container encrypted using the encrypting key of the end user system containing the decrypting key for decrypting at least part of the previously encrypted content stored on the computer readable medium as permitted; and playing at least part of the previously encrypted content by decrypting the secure container using the encrypting key of the end user system to access the decrypting key for decrypting at least part of the encrypted content.
