A Novel Approach to Text Steganography Using Font Size of Invisible Space Characters in Microsoft Word Document

Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 243)


Steganography is the hidden way of communication, where one individual communicates with another through cover medium without giving any doubt about the secret communication to the intermediary. In this paper, we propose a novel approach to text steganography in Microsoft Word document. The idea behind this technique is that slight variation in font size of invisible character space from other characters is not reflected in the document and in the required disk size for the document. Thus, steganography can be intelligently achieved. The embedding rate is very high in this technique, which increases with the increase in blank space character between words. The secret data hiding and revealing technique is presented.
