Abstract

PURPOSE: A system and a method for protecting information of multimedia streaming contents, and a recording medium recording the same are provided to safely protect a CONSTITUTION: An information providing system includes an encryption tool(110) generating a contents package(121) by encrypting a contents source(111), a providing tool(120) providing the encrypted contents package to a user, and a DRM(Digital Rights Management) server(130) generating/managing an encryption key and performing various certifications. A client system(140) includes a controller activating an application program and controlling a filtering tool, and the application program(144) receiving/playing the encrypted contents from the filtering tool. The data received by the filtering tool is received through a network driver connecting to an external network, and the multimedia streaming contents are a live/VOD(Video On Demand) method.
