Coverless Steganography Based on Motion Analysis of Video
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 With the rapid development of interactive multimedia services and camera sensor networks, the number of network videos is exploding, which has formed a natural carrier library for steganography. In this study, a coverless steganography scheme based on motion analysis of video is proposed.

An Image Encryption Scheme Based on Lorenz Hyperchaotic System and RSA Algorithm
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 This research proposes a new image encryption scheme based on Lorenz hyperchaotic system and Rivest–Shamir–Adleman (RSA) algorithm. Firstly, the initial values of the Lorenz hyperchaotic system are generated by RSA algorithm, and the key stream is produced iteratively.

Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 Recently, researchers have shown that coverless steganography is relatively safe. On this basis, to improve the payload of the coverless steganography, a novel semiconstruction coverless steganography algorithm is introduced in the paper. Firstly, web crawler technology is applied to crawl a wide range of small icons and hot news images from the ...

Code wars: steganography, signals intelligence, and terrorism [PDF]
, 2003 This paper describes and discusses the process of secret communication known as steganography. The argument advanced here is that terrorists are unlikely to be employing digital steganography to facilitate secret intra-group communication as has been ...

A method for automatic identification of signatures of steganography software [PDF]
, 2010 A fully automated, blind, media-type agnostic approach to steganalysis is presented here. Steganography may sometimes be exposed by detecting automatically characterized regularities in output media caused by weak implementations of steganography ...

A video coverless information hiding algorithm based on semantic segmentation
EURASIP Journal on Image and Video Processing, 2020 Due to the fact that coverless information hiding can effectively resist the detection of steganalysis tools, it has attracted more attention in the field of information hiding.
