Abstract

There is provided a method for use by a playback system to play back encrypted content associated with a first globally unique identifier (ID). The method includes storing an encrypted content in a memory being under control of a memory controller having a second globally unique ID, storing the first globally unique ID, transmitting a request from the memory controller to a license server, the request comprising the first globally unique ID, the second globally unique ID and a request for a content license to play back the encrypted content, receiving the content license enabling a right for the playback of the encrypted content, the content license including content keys and being encrypted to be decryptable according to a memory controller secret associated with the second globally unique ID, decrypting the content license, according to the memory controller secret to recover the content keys to a playback module.

Background

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to systems and methods for disseminating content to users for, and in particular to a system and method for portably binding license rights to content stored in optical media 2. Description of the Related Art

The digitization of audio visual media content such as television shows and movies has enabled viewers to purchase their own copies of such media content for personal enjoyment. Such media content may be disseminated via tangible media such as optical discs, or may be disseminated by downloading the digital media from a content server or kiosk to a writable medium for later playback. Unfortunately, the digitalization of such media content has also permitted large scale and widespread unauthorized dissemination and/or use. Such unauthorized dissemination and/or use deprive providers of the audio visual media content the economic benefit of authoring such material.

How to reduce such “piracy,” while retaining the benefits of widespread and easy dissemination of digital media content remains a challenge. However, the ubiquitous nature of digital communications and other technologies permit the definition of new dissemination and protection paradigms that can permit widespread dissemination of digital media, while suppressing unlicensed use of such digital media. The disclosure that follows describes an apparatus and method employing such a paradigm.

Claims

43. A method of for use by a playback system to play back encrypted content associated with a first globally unique identifier (ID), the method comprising: receiving the encrypted content; storing the encrypted content in a memory, the memory being under control of a memory controller having a second globally unique ID; storing the first globally unique ID in the memory or another memory accessible by the memory controller; transmitting a playback license request from the memory controller to a license server, the playback license request comprising the first globally unique ID, the second globally unique ID and a request for a content license to play back the encrypted content from the memory using the memory controller; receiving the content license enabling one or more rights to the encrypted content including a right for the playback of the encrypted content from the memory using the memory controller, the content license including one or more content keys and being encrypted to be decryptable according to a memory controller secret associated with the second globally unique ID; decrypting the content license by the memory controller, according to the memory controller secret associated with the second globally unique ID, to recover and provide the one or more content keys to a playback module; decrypting, using the playback module, the encrypted content using the one or more content keys to generate a decrypted content; and playing back, using the playback module, the decrypted content. || 53. A playback system for playing back encrypted content associated with a first globally unique identifier (ID), the playback system comprising: a memory; and a memory controller, the memory being under control of the memory controller having a second globally unique ID; the playback system configured to execute computer instructions to: receive the encrypted content; store the encrypted content in the memory; storing the first globally unique ID in the memory or another memory accessible by the memory controller; transmit a playback license request from the memory controller to a license server, the playback license request comprising the first globally unique ID, the second globally unique ID and a request for a content license to play back the encrypted content from the memory using the memory controller; receive the content license enabling one or more rights to the encrypted content including a right for the playback of the encrypted content from the memory using the memory controller, the content license including one or more content keys and being encrypted to be decryptable according to a memory controller secret associated with the second globally unique ID; decrypt the content license by the memory controller, according to the memory controller secret associated with the second globally unique ID, to recover and provide the one or more content keys to a playback module; decrypt, using the playback module, the encrypted content using the one or more content keys to generate a decrypted content; and playback, using the playback module, the decrypted content.
