Secured Approach for Hiding Data in MS Word Document Using MCDFF

Abstract

In the present electronic era to preserve the user data securely is a keen challenge. Nowadays, steganography is a rising orbit being utilized for guaranteed secure data transmission over the different mediums. Steganography is a technique which masks a message to hide its existence and make it appear "imperceptible by the eyes". It has been very clear that most of the text based steganography methods have the major drawback of low embedding efficiency. In this paper, authors have proposed a novel system of information hiding. The system targeted to MS Word structure known as Microsoft Compound Document File Format (MCDFF) to hide data within unused area and to make sure changes made to the Microsoft word document will not be detected as well as the original contents of file be kept as it is so that it looks like the normal file. The system has used Microsoft Word Document as a cover file.

“…Two aspects of digital manuscript files created by word processing programs are of interest from a forensic science and digital archeology perspective: their intentional manipulation for the purposes of hiding information (steganography) [1][2][3][4][5][6][7] and their use to identify content generation and editing processes that may shed light on the origin of the information contained in the files. The latter is of importance for understanding the nature, sequence, and extent of textual modifications in, say, policy documents.…”

Detecting Data Leakage from Hard Copy Documents

“…The data hiding is reversible in that the embedded information can be extracted to completely reconstruct the original Word document. Dasare and Dhore [3] leverage the Microsoft Compound Document File Format (MCDFF) to hide data in unused areas of a Word document while ensuring that the changes made to the document are not visible. Culnane et al [1] have enhanced the method of Zou and Shi [16] by applying multi-set modulation techniques to increase the data hiding capacities of binary document images; their approach employs automatic threshold computation, threshold buffering, shifted space distribution and letter space compensation techniques.…”
