In this paper, we are going to introduce different types of steganography considering the cover data. As the first step, we will talk about text steganography and investigate its details. Then, image steganography and its techniques will be investigated. Some techniques including Least Significant Bits, Masking and filtering and Transformations will be subjected during image steganography. Fina...

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...

Steganography is an art of hiding secret message in an unsuspecting cover document. Over the many years many systems have been proposed for the same. With the advancement of technical know-how even the cover medium has under gone certain changes. Generally the cover mediums used include text, image, audio and video. Text steganography is one of the oldest techniques of steganography which still...

Data transmission security has become an extremely important field of research. Steganography is an art of hiding information in image, audio and video files in a way that would meet the security requirements in the form of overt or covert. In this study, we propose a new hybrid steganography technique for color images that hide secret messages in the frequency domain of a cover image's blu...

Linguistic steganography is a branch of Information Hiding (IH) using written natural language to conceal secret messages. It plays an important role in Information Security (IS) area. Previous work on linguistic steganography was mainly focused on steganography and there were few researches on attacks against it. In this paper, a novel statistical algorithm for linguistic steganography detecti...

“Maintain the security of the secret informat ion”, this words has been a great challenge in our day to day life. Sender can send messages regularly through a communicat ion channel like Internet, draws the attention of third parties, hackers and crackers, perhaps causing attempts to break and expose the unusual messages. Steganography is a gifted region which is used for secured data transmiss...

In this paper we review different Steganography techniques for hiding the data. Steganography is a technique of hiding the data in any media in such a way that it remains confidential. This paper explores the different method of data hiding: image steganography, audio steganography, video steganography, text steganography, steganography in spatial domain, transform domain and adaptive steganogr...
