The System Of Privacy Information Protection Design And Implementation

Privacy,which means that the secret information in the life of individual citizens which do not want others to know or be public.And most of the privacy information of computer users is stored in the file Hard Disk as files.According to this case,this paper discuss how to protect the privacy information in local files with monitoring the operation of other programs to the local files in the computer.Nowadays,most of File monitoring programs run in User Mode,implemented with API HOOK.However,it has a negative affect to the efficiency of the system, and the information which is got by the File monitoring program is not comprehensive enough.For this reason,I monitor the file operation with the kernel driver which can recognise the file operation accurately and has little affect to the system.The File System filter dirver is a file system filter driver behavior can be attached to the file system and modify operations optional drive. File system filter driver is running as part of the NT Executive kernel-mode components. It can filter I / O to one or more file systems, file operations, the characteristics of the drive, the filter means can be logging, monitoring, modification or even blocking operation. File system filter driver Typical applications include anti-virus programs, encryption, multi-tiered storage management systems.Minifilter driven by Microsoft proposed a new file system filter driver model. Which itself is a driver. It is located in I / O manager and file systems, Lee callback mechanism, a clear user-defined filtering required IRP. Filter Manager to bind to the target volume’s file system stack, Minifilter filtering required to drive I / O operations, through the filter Manager Registration indirectly bound to the file system stack. Minifilter with programming is relatively simple, shorten development time, flexible loading and unloading, and more friendly support user-mode applications and so on. In this paper, the file system filter driver and the upper micro applications combine to achieve computer users and the protection of privacy file monitoring function. Able to effectively monitor the user’s because the file to protect it is not illegal to steal.
