Recently, the field of steganography has experienced rapid developments based on deep learning (DL). DL distributes secret information over all available bits cover image, thereby posing difficulties in using conventional steganalysis methods to detect, extract or remove hidden images. However, our proposed framework is first effectively disable covert communications and transactions that use s...

Network steganography encompasses the information hiding techniques that can be applied in communication network environments and that utilize hidden data carriers for this purpose. In this paper, we introduce a characteristic called steganographic cost, which is an indicator for the degradation or distortion of the carrier caused by the application of the steganographic method. Based on exempl...

The paper presents a new steganographic method called RSTEG (retransmission steganography), which is intended for a broad class of protocols that utilises retransmission mechanisms. The main innovation of RSTEG is to not acknowledge a successfully received packet in order to intentionally invoke retransmission. The retransmitted packet carries a steganogram instead of user data in the payload f...

Hiding information in network traffic may lead to leakage of confidential information. In this paper we introduce a new steganographic system: the PadSteg (Padding Steganography). To authors’ best knowledge it is the first information hiding solution which represents inter-protocol steganography i.e. usage of relation between two or more protocols from the TCP/IP stack to enable secret communic...

Now-a-days, digital communication is part of every computing system. As the usage is increasing in every aspect of data transfer and sharing; so is the threat of information stealing and security. Data Security over the public network is the major concern of every communication expert. Cryptography and Steganography are the major techniques employed for hiding and securing the data from the cha...

The popularity of steganography in the data exfiltration of private corporate sensitive data is increased. So it is important to detect such malicious activity. Becausethe data being transferred can hide the large amount of data in video becoming increasingly attractive. To ensure privacy and security we proposed an effective steganalysis method to detect hidden data in video by using the SDN f...

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...
