Abstract

A system and method for securely streaming encrypted digital media content out of a digital container to a user'"'"'s media player. This streaming occurs after the digital container has been delivered to the user'"'"'s machine and after the user has been authorized to access the encrypted content. The user'"'"'s operating system and media player treat the data stream as if it were a being delivered over the Internet (or other network) from a streaming web server. However, no Internet connection is required after the container has been delivered to the user and the data stream suffers no quality loss due to network traffic or web server access problems. In this process of the invention, the encrypted content files are decrypted and fed to the user'"'"'s media player in real time and are never written to the user'"'"'s hard drive or storage device. This process makes unauthorized copying of the digital content contained in the digital container virtually impossible.

Claims

1-47. -47. (canceled)

48. A method of providing electronic data, the method comprising the steps of:

providing by a computing device a secure streaming container (SSC) to a second device, the SSC having at least streaming media content, a container identification and an associated original key;

receiving data unique to the second device at the computing device;

processing the received data and the container identification to produce a permission token; and

initiating sending of the permission token to the second device,

wherein the SSC includes content that is configured to rekey the original key using the permission token and configured to rekey the streaming media content so that decryption of the streaming media content is locked to the second device.
