Coverless Steganography Based on Low Similarity Feature Selection in DCT Domain [PDF]
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 ...

Deep Learning-Based Coverless Image Steganography on Medical Images Shared via Cloud
Coverless image steganography is an approach for creating images with intrinsic colour and texture information that contain hidden secret information. Recently, generative adversarial networks’ (GANs) deep learning transformers have been used to generate

Steganography-based secret and reliable communications: Improving steganographic capacity and imperceptibility [PDF]
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]
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 ...

A Novel Coverless Text Steganographic Algorithm Based on Polynomial Encryption
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 image steganography based on DenseNet feature mapping
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 Video Steganography Based on Audio and Frame Features
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 ...

[Retracted] A Review of Motion Vector‐Based Video Steganography
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 ...
