Coverless Steganography Based on Low Similarity Feature Selection in DCT Domain [PDF]
Radioengineering, 2023 Coverless image steganography typically extracts feature sequences from cover images to map information. Once the extracted features have high similarity, it is challenging to construct a complete mapping sequence set, which places a heavy burden on the ...

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 ...
