Abstract: PURPOSE: An internet host system security evaluation method and system is provided to identify a protocol from packet data generated for offering a function of a packet security at an internet host system, to collect the packet data, and to extract risk elements from the packet data. CONSTITUTION: The system comprises a system configuration block, a database control block, and a rule interpreter block. The system configuration block performs a user authentication by a manager having a management right, and registers data on an agent performed at a remote host and data on a module performed by an evaluation rule. The database control block generates a table on the data transmitted by the agent, adds data, defines an assessment evaluation rule at rule data, modifies the assessment evaluation rule or erases the evaluation rule from the rule data. The rule interpreter block reads the evaluation rule, defined at the database management block, from the rule data, analyzes instructions according to an execution procedure, and executes the evaluation rule. The system includes a GUI(Graphic User Interface) diagram and a socket handler. The GUI diagram enables a manager to set overall elements needed for an assessment via a JAVA interface. The socket handler enables the agent and the execution module to transmit data over a network.

Abstract: PURPOSE: A multimedia contents service apparatus and a method thereof are provided, which can reduce the cost and traffic of the streaming server and the extraction unit by establishing the multicast tree according to each layer of the scalable media contents. CONSTITUTION: A media streaming server(200) creates the scalable media contents by performing the scalable media encoding about the arbitrary multimedia contents. Multicast trees(202/1,202/2,202/3) are formed in each layer so that the generated scalable media contents is transferred to each layer. Client terminals output the received scalable media contents.

Abstract: 본발명은멀티미디어콘텐츠서비스에관한것으로, 특히스케일러블미디어콘텐츠(scalable media contents)를전달하는데적합한멀티캐스트트리(multicast tree) 구축방법과이 구조에서콘텐츠접근제어기능을제공하기위한보안구조에관한것이다. 기존의멀티미디어영상의경우하나의멀티캐스트트리만으로콘텐츠를배포하는것이가능하지만, 스케일러블미디어콘텐츠의경우다양한디바이스간에수신해야할 레이어(layer)들이서로상이하기때문에기존의단일멀티캐스트트리구축방식으로는콘텐츠배포가불가능하다는문제가있다. 이에본 발명은, 스케일러블미디어의전송에최적화된멀티캐스트트리의구축방법을제안하고, 구축된멀티캐스트트리를통해전송되는스케일러블미디어에대한접근제어를제공하기위한보안구조를함께제공한다. 이를위해본 발명에서는, 스케일러블미디어콘텐츠의각 레이어별로멀티캐스트트리를구축하여해당레이어에대한미디어스트림을전달하는방식을제안한다. 또한, 스트리밍미디어의접근제어를위해하나의레이어에해당하는스트림에대해서만암호화하여전송하는방식을제안한다.
