As a new information hiding method, coverless information hiding has become a hot issue in the field of information security. The existing coverless information hiding method can hide only one Chinese character in each natural text. However, the problem of the method is that the hiding capacity is too small. To address this problem, a new method named coverless multi-keywords information hiding...

In this paper, different steganographic methods have been analyzed and implementations of those techniques have been performed. Those methods include hiding in text, hiding in audio file, hiding in file system, and hiding in image files.

Digital fingerprinting becomes paid growing attention as a technology resolving copyright problems. Previously, researchers have been only interested in image based digital fingerprinting where secret information is hidden in images, and text have not been the main target of hiding information. In this paper, we propose an information hiding method for text. Our information hiding method is bas...

This paper presents a survey of text steganography methods used for hiding secret information inside some covertext. Widely known hiding techniques (such as translation based steganography, text generating and syntactic embedding) and detection are considered. It is shown that statistical analysis has an important role in text steganalysis.

Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...

This paper proposes a text-based data hiding method to insert external information into Microsoft Word document. First, the drawback of low embedding efficiency in the existing text-based data hiding methods is addressed, and a simple attack, DASH, is proposed to reveal the information inserted by the existing text-based data hiding methods. Then, a new data hiding method, UniSpaCh, is proposed...
