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 ...

Steganography-based secret and reliable communications: Improving steganographic capacity and imperceptibility [PDF]
, 2010 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Unlike encryption, steganography hides the very existence of secret information rather than hiding its meaning only.

JPEG steganography: A performance evaluation of quantization tables [PDF]
, 2009 The two most important aspects of any image based steganographic system are the imperceptibility and the capacity of the stego image. This paper evaluates the performance and efficiency of using optimized quantization tables instead of default JPEG ...

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.

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-

A Novel Coverless Text Steganographic Algorithm Based on Polynomial Encryption
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Aiming at the problems of low text utilization rate and ambiguity of secret information extraction in the “tag + keyword” coverless information hiding methods, we propose a coverless information hiding method of Chinese text based on polynomial encryption in this paper.

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 ...
