Hiding data in the file structure
Journal Title: КОМП’ЮТЕРНІ НАУКИ ТА КІБЕРБЕЗПЕКА - Year 2018, Vol 1, Issue 9
Abstract
In this paper, the methods of steganography hiding of information in a file system structure is investigated. Namely, the structure of the FAT file system (File Allocation Table) and methods of hiding information messages, which are based on repositioning separate clusters of cover files. A new method is proposed that, unlike the known ones, changes the order of alternation of clusters in each cover file, which allows to further hide a certain informational message, that is, to increase the capacity of the hidden channel. It was confirmed that the results of the data concealment and deletion procedures largely depend on the number of clusters with which it is necessary to carry out the appropriate transformations. It is noted that the extraction procedure is performed much faster than hiding the message. The proposed method is implemented programmatically, the results of experimental researches confirmed the adequacy of the theoretical conclusions and recommendations.
