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.

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 ...

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 ...

Coverless image steganography based on DenseNet feature mapping
EURASIP Journal on Image and Video Processing, 2020 Since the concept of coverless information hiding was proposed, it has been greatly developed due to its effectiveness of resisting the steganographic tools. Most existing coverless image steganography (CIS) methods achieve excellent robustness under non-

Coverless Steganography for Digital Images Based on a Generative Model [PDF]
, 2018 In this paper, we propose a novel coverless image steganographic scheme based on a generative model. In our scheme, the secret image is first fed to the generative model database, to generate a meaning-normal and independent image different from the ...
