Due to the development of Internet technologies and large-scale multimedia content technology, a growing number of companies are providing various high-quality media services. The convenience of digital information has increased the demand for digital contents. With the advantage of ease of production and storage, the production of digital contents has increased, and with the development of cloud technology, it is easy to store and manage such high capacity digital media contents Service to the user. In addition, to facilitate the use of cloud media services on more devices, a new media environment called N-screen has emerged. N-screen is a service that provides content from multiple devices capable of Internet access. It is a technology that can enjoy without interruption. Accordingly, various media service providers store high-capacity media files on a cloud server and provide N-screen based streaming or download services to users.

In order to service digital media contents, secure transmission and use of contents should be considered first, and a service provider of media contents is applying DRM (Digital Rights Management) technology for content copyright protection. DRM technology provides a series of protection and management systems for the prevention of illegal copying of content and the acquisition of use rights of contents, generation and distribution of contents, and use of contents.

Since DRM technology is used to control the use of digital contents in the same DRM technology, DRM technology is generally dependent on one platform. In order to be used on multiple platforms, new DRM technology should be applied . Since the DRM technology is platform-dependent, if the file is copied / moved to the platform environment different from the first downloaded platform, the file can not be authenticated and the decryption / re-encryption process of the media content file There is a problem in that additional cost due to network transmission or the like may occur in the process of authenticating and using the new DRM information through the current platform.

Therefore, in order to solve this inconvenience, the media contents provider wants to use various DRM by applying a single content protection technology. As a technology supporting this, the DRM technology does not apply different encryption methods, However, in order to use the media contents protected by the common encryption method in different terminals, there is a problem that information about a plurality of DRM technologies must be included in the contents.
