Research And Implementation Of WINDOWS File Protection System Based On Filter Driver

With the computer technology and the rapid development of network technology, as well as large enterprises, public utilities and other units have internally the various operational systems, service system, the establishment of rapid growth in the number of public documents. Many of these documents are classified documents, and these classified documents are often stored in a scattered manner across the enterprise backbone technology or business employee's computer. Because some staff safety awareness to prevent weak or weak, leading to the classified files directly maliciously staff faced internal security threats.At the beginning of the thesis introduces status of file-protection and file encryption, analysis advantages and disadvantages of file-hiding technologies, and designs a mean of file-protection based on Windows file system filter driver technology. This mean can effectively improve the documentation and data security.There was close relationship between file system filter-driver and operating system. Papers analyzed components on the Windows system, and focused on the Windows filter driver technology, the same time, in order to achieve encryption file protection system, designed a set of encryption scheme, the final papers to the out the filter driver based on a hidden system file protection function modules to achieve, transparent encryption to achieve, as well as the overall design.
