Apparatus for processing method-embedded content and method thereof

An apparatus for processing a method-embedded content comprising:

• a content packager for packaging and encoding a content, metadata, and method, and attaching an electronic signature thereto if needed;
• a content unpackager for separating the content, metadata, and method from the packaged content, respectively, checking the electronic signature if it is attached to the content, metadata, and method, and decoding the content, metadata, and method if they are encoded;
• a method manager section for checking if the method is a normal code, and managing the method extracted from a package;
• a method execution environment section for securing a safe execution of the method by constructing an environment independent of other parts of a system;
• an access control section for reading and analyzing the metadata, judging whether a software that accesses the metadata is authenticated if needed, and controlling an access of the method for the content and metadata only in an authenticated software module;
• an authentication management section for managing to authenticate the software module that intends to access the content if the authentication is needed;
• and
• a content player for providing an access application program interface (API) with respect to the content, metadata, and method, managing authentication information of the software, and processing the method-embedded content by requesting the execution of the method and receiving a result of the method execution.
