    • The present invention relates to the information protection of digital content transferred by streaming and download service through wire or wireless Internet network. The information protection system in this invention suggests a drastic prevention method of copyrights infringement such as illegal copy and unauthorized distribution of digital content, by using of the encryption, decryption, distribution, and authentication technologies. This invention suggests the control technology of general viewer program, not the specific viewer program for information protection, using a network filter driver for streaming and file system filter driver for download service. The main function of network and file system filter driver is the filtering operation such as a hooking, changing, decrypting, and restoring of message and data packet, and transferring to the viewer program. The main idea and technology of this invention suggest higher secure and efficient digital information protection system for live/VOD/HTTP streaming and download service.
    • 本发明涉及通过有线或无线因特网网络流式传输和下载服务传输的数字内容的信息保护。 本发明的信息保护系统通过使用加密,解密,分发和认证技术,提出了非法复制和非法分发数字内容等版权侵权的大力预防方法。 本发明提出了一般观看者节目的控制技术,而不是用于信息保护的特定观看者节目,使用用于流媒体的网络过滤器驱动程序和用于下载服务的文件系统过滤驱动器。 网络和文件系统过滤驱动的主要功能是消息和数据包的挂接,更改,解密和恢复等过滤操作,并传送给观众节目。 本发明的主要思想和技术提出了用于实时/ VOD / HTTP流和下载服务的更安全高效的数字信息保护系统。
