Steganography is the art of inconspicuously hiding data within data.Steganograhy goal in general is to hide data well enough so that unintended recipients do not suspect the Steganographic medium of containing hidden data. As privacy concern to develop along with the digital communication domain, steganography will undoubtedly play a growing role in the society. For this reason, it is important...

Until now hiding methods in network steganography have been described in arbitrary ways, making them difficult to compare. For instance, some publications describe classical channel characteristics, such as robustness and bandwidth, while others describe the embedding of hidden information. We introduce the first unified description of hiding methods in network steganography. Our description me...

Network steganography is a covert communication technique that uses redundancies in network protocols to transfer secret information. The retransmission-based steganography (RSTEG) embeds covert messages into the payload field of the intentionally retransmission packets. So its capacity is higher than most of the existing methods. Because TCP checksum field of the original packet is different f...

In this paper, Cryptography and Steganography techniques are combined to enhance the security level of data communication over an unsafe distributed network. The standard LSB(Least Significant Bit) steganography method is also modified by digitally signing a information of starting position of hided message in image, so that any other third person can’t determine the position of beginning of hi...

This paper presents study about how to hide the useful information and give the superficial knowledge of Steganography, compare encryption, and cryptography. This paper describes the present, past and future of Steganography. In this paper, we introduce Steganalysis for computer forensic investigation. Digital forensics is helpful in investigation of the cyber-crime and computer crime. With the...

Securing data is a challenging issue in today’s era. Most of the data travel over the internet and it becomes difficult to make data secure. So Cryptography was introduced for making data secure. But alone cryptography cannot provide a better security approach because the scrambled message is still available to the eavesdropper. There arises a need of data hiding. So here we are using a combina...

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...

In this paper, a novel strategy of Secure Steganograpy based on Generative Adversarial Networks is proposed to generate suitable and secure covers for steganography. The proposed architecture has one generative network, and two discriminative networks. The generative network mainly evaluates the visual quality of the generated images for steganography, and the discriminative networks are utiliz...
