Coverless Video Steganography Based on Audio and Frame Features

Security and Communication Networks, Volume 2022, Issue 1, 2022., 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 ...

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 ...

[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 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-
