Coverless Image Steganography: Review
Academic Journal of Nawroz University, 2022 Many of the existing image steganographic techniques embed secret information into cover images by slightly altering their contents. These modifications have several effects, on the other hand, Stego-images distorted by these problems become vulnerable to steganalysis tools. Coverless information hiding represents a solution to this problem.

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 ...

Hyper Coupled Map Lattices for Hiding Multiple Images
Complexity, Volume 2023, Issue 1, 2023., 2023 The concept of a hyper coupled map lattice (CML) is presented in this paper. The complexity of the lattice is increased not by adding another spatial dimension of the lattice but by replacing scalar nodal variables by multidimensional square matrices of iterative variables.

IET Image Processing, Volume 16, Issue 11, Page 2854-2862, 18 September 2022., 2022 Abstract Information hiding aims to embed a crucial amount of confidential data records into the multimedia, such as text, audio, static and dynamic image, and video. Image‐based information hiding has been a significantly important topic for digital forensics. Here, active image deep steganographic approaches have come forward for hiding data.

Steganographic secret sharing via AI-generated photorealistic images
EURASIP Journal on Wireless Communications and Networking, 2022 Steganographic secret sharing is an access control technique that transforms a secret message into multiple shares in a steganographic sense. Each share is in a human-readable format in order to dispel suspicion from a malicious party during transmission

[Retracted] A Review of Motion Vector‐Based Video Steganography
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Steganography is a popular research direction in the field of information security. Due to the widespread use of video media, video steganography has received much attention from the research community. Among video steganography, motion vector (MV)‐based video steganography has become one of the critical concerns of researchers due to its large ...

Coverless information hiding based on the generation of anime characters
EURASIP Journal on Image and Video Processing, 2020 To fundamentally resist the steganalysis, coverless information hiding has been proposed, and it has become a research hotspot in the field of covert communication. However, the current methods not only require a huge image database, but also have a very
