Coverless Video Steganography Based on Audio and Frame Features
Security and Communication Networks, 2022 The coverless steganography based on video has become a research hot spot recently. However, the existing schemes usually hide secret information based on the single-frame feature of video and do not take advantage of other rich features. In this work, we propose a novel coverless steganography, which makes full use of the audio and frame image ...

Source activity correlation effects on LCMV beamformers in a realistic measurement environment. [PDF]
Comput Math Methods Med, 2012 In EEG and MEG studies on brain functional connectivity and source interactions can be performed at sensor or source level. Beamformers are well‐established source‐localization tools for MEG/EEG signals, being employed in source connectivity studies both in time and frequency domain.

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
