Steganography is the technique of hiding secret information within any media like text, images, audio/video and protocol based network. Steganography is an important area of research in recent years involving a number of applications. The modern secure image steganography presents a challenging task of transferring the embedded information to the destination without being detected. Transform do...

Steganography refers to information or file that has been concealed inside a digital media. Steganalysis is used to detect and/or estimate potentially hidden information from observed data with a little or no knowledge about the steganography algorithm and its parameters. Current trend in steganalysis seems to suggest two extreme approaches (a) little or no statistical assumption about the imag...

Protocol steganography allows users who wish to communicate secretly to embed information within other messages and network control protocols used by common applications. This form of unobservable communication can be used as means to enhance privacy and anonymity as well as for many other purposes, ranging from entertainment to protected business communication or national defense. In this pape...

Steganography is the art of information hiding. In today’s digital age messages can be hidden in images, sound files, text, and other digital objects. To a casual observer, these messages are invisible. The use of steganography on public networks, such as the Internet, is unknown due to its stealthy nature. Unless it is being actively looked for, one would not know that it is there. For example...

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...

With the explosive growth of internet and the fast communication techniques in recent years the security and the confidentiality of the sensitive data has become of prime and supreme importance and concern. To protect this data from unauthorized access and tampering various methods for data hiding like cryptography, hashing, authentication have been developed and are in practice today. In this ...

This paper is all about the study of the steganography and techniques used for the steganography. Firstly we will understand the term steganography, use of steganography and techniques used for the steganography. In steganography, we use text transformation, LSB (Least Significant Bit), graphics or image steganography, audio steganography, steganography in videos and animations etc. This paper ...

Steganography is a method of secret communication wherein the very existence of communication is hidden. During the last few decades there have been a tremendous development in digital image steganography and a large number of papers have been published by different researchers. This review paper presents a classification of the spatial domain image steganography techniques. These classificatio...

Steganography is the art and science of hiding secret data to provide a safe communication between two parties and it is a prominent branch in the information hiding research area. Cryptography is the process of conversion of data into scrambled code that can be deciphered and sent across a public or private network. This paper presents a novel approach for Audiography-Combination of Audio Steg...

In this paper we propose a new technique for secret communication of a digital image through a network exposed to attackers. The security is achieved by a combination of two popular information security techniques: Cryptography and Steganography. We have used a modified version of AES for encryption which uses a keystream generator(W7) and four techniques for steganography (one in spatial and t...
