Embodiment Construction

[0018] Digital Rights Management (DRM) is an inclusive system for supporting security and copyright management of all digital content. For this purpose, the first consideration is server-based security processing. For example, but not limited to, methods are contemplated that allow only one user who has been granted special rights to access a server and download media files or receive media streams sent in real time to play content.

[0019] However, since content once downloaded can be distributed at high speed through a peer-to-peer (P2P) search function, digital content cannot be protected in a secure manner using only server-based security processing unless the files in exchange are securely processed .

[0020] Furthermore, a method of manipulating data bits in a header portion of a media file can be considered. However, this method is not suitable for secure processing as it is highly vulnerable to hackers and the terms of service may not be secure since the manipulati...

Abstract

A system and a method for allowing a plurality of devices interconnected for home networking to use the contents only by a single license without acquiring separate licenses for the devices. A transceiver module transmits / receives data to / from various devices. A license search module receives a request to issue a license from a home device through the transceiver module, searches for a corresponding formal license in a license storing module, and transmits the search result to both a license request module and a temporary license issuing module. The license request module requests the license server to issue the corresponding formal license when the formal license does not exist in the license storing module, and stores the license downloaded from the license server. The temporary license issuing module issues a temporary license to the corresponding home device through the transceiver module, based on the formal license stored in the license storing module.

Description

technical field [0001] The present invention relates to a system and method that provides a technology that can be used to transmit encrypted content from a content provider to a user and prevent illegal copying of the transmitted content in the Internet environment, and more particularly, to a system that allows A system and method for multiple devices interconnected over a network to use the content by utilizing only a single license without the need to acquire different licenses for devices interconnected within a home network. Background technique [0002] like figure 1 As shown, a digital rights management (DRM) system of the related art includes: a Web server that distributes media files; a license server that distributes a license corresponding to each device; Downloaded media files to the device. When personal computers (PCs) exist only in one place, there is no problem or limitation in using such a related technology DRM system. [0003] Currently, multiple devic...
