摘　　要：由于对数字多媒体产品的版权管理、传播追踪以及安全验证和版权保护的需要,数字水印技术得到了空前的发展,但是把数字水印应用到文件系统中来保护版权和记录操作系统的关联性还是一个开创性的尝试。在此,文章介绍了ISTFS文件系统以及该文件系统的安全机制,然后把数字水印技术应用到ISTFS文件系统中,通过文件中的数字水印信息记录操作系统的关联性,不但实现了对数字文件的版权保护和传播追踪,而且达到了对文件系统的开发者及所有者权益的保护,这也是数字水印技术在操作系统安全机制中应用的最新尝试。Because the DRM, tracing, security validation and copyright production for the digital files appear more urgent. Watermark is developed prodigiously these years and it is becoming the studying focus of information security technology, but it is a new taste of digital watermark＇s application in the security system to copyright protection and recording the relatiomhip of watermark information. At first, the paper expatiated on the intrinsic secure transacted flash file system and its security system. And then watermark is appalicated in intrinsic secure transacted flash file system. Through the relationship of watermark information recording operating system, not only the digital files＇ copyright protection and transmitting trace are achieved, but also the system developer and owner＇s rights and interests are protected, which is a new taste of digital watermark＇s application in the security system.
