Description

Contents license management system and method

The present invention relates to a content license management system and method. More specifically, when a user registers digital content on a server, the user registers a list of playback devices together with license information, and the user downloads the digital content through the playback terminal. The present invention relates to a content license management system and method for allowing a user to download or play digital content after receiving a license right through a server and confirming whether a playback device is included in a registered player list.

Recently, digital services that sell digital contents such as digital music, images, videos, books, and games through networks have become commonplace. To protect such commercial digital intellectual property rights and avoid digital infringement, digital rights management (DRM) systems that can be used to prevent unauthorized access to digital content and to manage digital content usage rights are required. Do.

The key concept in DRM is the use of digital licenses. The license is a digital data file containing Content Decryption Keys and Contents Usage Rules. In other words, the license refers to data that contains the decryption key used to decrypt the encrypted content and the contents specifying the right to use (number, duration) of the content. In addition, metadata (meta data) refers to data that describes the data, for example, data that contains a description of the content. A packager is a device that performs a series of tasks by encrypting content using an encryption key and attaching a header containing a URL for obtaining a license and information on a commerce vendor. Clearing House is a system that performs license issuance, statistical function, billing, financial settlement and settlement to solve encrypted contents by packager, and plays a key role of DRM system.

In DRM, a user purchases a license that grants certain rights to access the content, rather than purchasing the content directly. The terms of use specify how the content should be used, such as copy permission, pay-per-view, weekly rental, and so on. Licenses can be described using a language that represents copyright, such as eXtensible rights Markup Language (XrML), which has been selected by the Video Experts Group (MPEG) for the MPEG-21 multimedia framework. have.

In DRM implementations, encrypted content can be supplied via any communication medium, such as client / server systems, super-distribution, digital audio / video broadcasts, but does not possess a valid license. Unless you can decrypt the content. Thus, protected content can be supplied regardless of any license. More specifically, when the user attempts to consume the protected content, the player device checks if there is a valid license for the content on the user device. If the player device does not find a license, the player device denies access to the content and informs the user that he needs to connect to the license server to obtain a valid license. After you provide the fee and / or information that may be required to obtain a license, the license will be transferred to your device, and the protected content may be decrypted and used in accordance with the terms or conditions of use within the license. have.

On the other hand, the user can download the digital content to the player device that can reproduce the digital content produced by various compression methods or purchase a storage medium on which the digital content is recorded and can use it when necessary.
