Research of a Secure File System for Protection of Intellectual Property Right

This paper analyses the architecture of current secure file system and the security needs for protection of intellectual property rights and especially the major problems of it. Then we propose a secure data container model based on data encapsulation from the realization concept of virtual file system (VFS) in Linux. Based on this model, we design and implant a secure file system IPR-SFS on Windows platform for protection of intellectual property which achieves perfect combination between data encryption and access control. Compared with the previous systems, the IPR-SFS file system is more convenient and flexible, safe and scalable, also comparable to the existing file.
