Coverless Image Steganography using Haar Integer Wavelet Transform
2020 Fourth International Conference on Computing Methodologies and Communication (ICCMC), 2020Coverless hnage steganography is a recently discovered steganography method Which does not modify the image carrying the secret information. However, the techniques proposed until now have low efficiency capable of transferring few bits per image. This paper focuses on increasing the amount of data transmitted in an image, when using coverless image ...

A Robust Coverless Steganography Scheme Using Camouflage Image
IEEE Transactions on Circuits and Systems for Video Technology, 2022Recently, most coverless image steganography (CIS) methods are based on robust mapping rules. However, due to the limited mapping expression relationship between secret information and hash sequence, it is a challenge to further improve the hiding ability of coverless information hiding.

Coverless Image Steganography Based on Multi-Object Recognition
IEEE Transactions on Circuits and Systems for Video Technology, 2021Most of the existing coverless steganography approaches have poor robustness to geometric attacks, because these approaches use features of the entire image to map information, and these features are easy to be lost when being attacked. In order to improve the robustness against geometric attacks, we propose a coverless image steganography method based

Towards a high capacity coverless information hiding approach
Multimedia Tools and Applications, 2021Most of the coverless information hiding approaches use a set of cover images as stego-images which make them unsuitable for real-time applications. Moreover, the parameters that affect the hiding capacity and the robustness against image processing attacks are not explicitly studied.

Coverless Image Steganography Without Embedding
2015The traditional image steganography technologies designate a cover image and embed secret data into it to form the stego-image. However, the modification traces caused by the embedding will be left in the cover image, which makes successful steganalysis possible.

Coverless image steganography using partial-duplicate image retrieval
Soft Computing, 2018Most of the existing image steganographic approaches embed the secret information imperceptibly into a cover image by slightly modifying its content. However, the modification traces will cause some distortion in the stego-image, especially when embedding color image data that usually contain thousands of bits, which makes successful steganalysis ...

A Coverless Image Information Hiding Algorithm Based on Fractal Theory
International Journal of Bifurcation and Chaos, 2020To improve the robustness and imperceptibility of the existing coverless image information hiding, a generative coverless image information hiding algorithm based on fractal theory is proposed in this paper. Firstly, four fractal image generation methods are analyzed, and the relationship between the coverless information hiding and these methods is ...

Coverless Image Steganography Framework with Increased Payload Capacity
2019 IEEE International Symposium on Multimedia (ISM), 2019This paper proposes a coverless image steganog- raphy framework with increased payload hiding capacity for confidential information transmission. This is superior to existing coverless schemes which require transmitting a stream of stego images in sequence due to the issue of small hiding capacity per stego image.

Coverless Information Hiding Based on Robust Image Hashing
2017Traditional image steganography modifies the content of the image more or less, it is hard to resist the detection of image steganalysis tools. New kind of steganography methods, coverless steganography methods, attract research attention recently due to its virtue of do not modify the content of the stego image at all.
