Abstract
Provided is digital rights management (DRM) provision technology, and more particularly, are an apparatus, system, and method which can easily provide content using one or more DRM systems. A DRM provision apparatus includes a content download unit which downloads encrypted real content and dummy content from a download server and which manages the downloaded real content and dummy content; a license management unit which manages a license issued by a license server; and a processing unit which manages the downloaded real content and dummy content and the issued license.
Claims23
A digital rights management (DRM) provision system comprising:
- a packaging server which performs first packaging operation of encrypting a specific content to generate encrypted content, and a second packaging operation of generating at least one dummy content corresponding to the encrypted content and encrypting the dummy content to generate encrypted dummy content, wherein the at least one dummy content is a file required to receive a license for each DRM, and a first encryption key of the encrypted content is include in a body of the dummy content;
- and
- a DRM provision apparatus which receives the encrypted content and at least one dummy content corresponding to the encrypted content, analyzes a DRM header of the received dummy content to request a license for the encrypted content, decrypts the dummy content based on the requested license, and decrypts the encrypted content using the decrypted dummy content,
- wherein the first packaging operation comprises:
- generating a DRM header of the specific content;
- generating the first encryption key for encrypting the specific content;
- and
- encrypting the specific content using the DRM header and the first encryption key, and
- wherein the second packaging operation comprises:
- generating a second encryption key for encrypting the dummy content;
- and
- encrypting the dummy content using the second encryption key.
A packaging server comprising:
- a first packaging unit which encrypts content registered in a contents management system to generate encrypted content;
- and
- a second packaging unit which generates at least one dummy content corresponding to the encrypted content, and encrypts the dummy content to generate encrypted dummy content,
- wherein the at least one dummy content is a file required to receive a license for each DRM, and a first encryption key of the encrypted content is included in a body of the dummy content,
- wherein at least one from among the first packaging unit and the second packaging unit is a hardware component, and
- wherein the second packaging unit generates a second encryption key for encrypting the dummy content, and encrypts the dummy content.
A packaging method comprising:
- at a packaging unit, performing a first packaging operation of encrypting content registered in a contents management system to generate encrypted content;
- and
- a second packaging operation of generating at least one dummy content corresponding to the encrypted content, and encrypting the dummy content to generate encrypted dummy content,
- wherein the at least one dummy content is a file required to receive a license for each DRM, and a first encryption key of the encrypted content is included in a body of the dummy content, wherein the packaging unit is a hardware component,
- wherein the first packaging operation comprises:
- generating a DRM header of the registered content;
- generating the first encryption key for encrypting the content;
- and
- encrypting the content using the DRM header and the first encryption key, and wherein the second packaging operation comprises:
- generating a second encryption key for encrypting the dummy content;
- and
- encrypting the dummy content using the second encryption key.
