| Abstract [eng] |
This work is based on the problem of information hiding in computer disk drives. Firstly, the object of study, i.e. clustered file systems, their fragmentation, ways to hide information, has been analyzed. Moreover, currently existing methods to hide information in computer disks has been reviewed. Then, a new covert channel method, designed to hide data in clustered file systems, has been proposed. The method uses multiple cover files and hides data by changing relative positions of clusters of those files. Finally, an experimental application that exploits the proposed method has been created. With the help of the application the method has been examined and it is proved that it has the property of two-fold plausible deniability. |
