A Light-weight File Hiding Scheme

Mess storage devices permeate in our modern society, such as government, academic organization, business area and individuals. To various computer users, especially the first three, security and safety of the sensitive data stored on the storage media is the key issue. After loss of devices with important data, the way to protect sensitive data against aggression from illegal user is gaining more and more concern in modern storage technology field.Among various mainstream file system, NTFS (New Technology File System) is widely equipped on personal computer because of popularity of Microsoft Windows Operation system. This paper will introduce a new data concealment scheme based on NTFS. This method takes advantage of the way NTFS organizes files. Combining random data scrambling algorithm with tiny modification on data block points of the file system, a new data concealment scheme is proposed which has optimized time and space efficiency. Hence, this scheme provides strong sensitive data protection ability while only occurs little computation penalty.
