Lossless Image Steganography Based on Invertible Neural Networks
Entropy, 2022 Image steganography is a scheme that hides secret information in a cover image without being perceived. Most of the existing steganography methods are more concerned about the visual similarity between the stego image and the cover image, and they ignore

Multi Secret Image Sharing Scheme of General Access Structure with Meaningful Shares
Mathematics, 2020 A Multi Secret Image sharing scheme can share several secret images among certain participators securely. Boolean-based secret sharing schemes are one kind of secret sharing method with light-weighted computation compared to the previous complex ...

A Secret Image Sharing Based on Logistic-Chebyshev Chaotic Map and Chinese Remainder Theorem [PDF]
Computer Science Journal of Moldova, 2023 Visual secret sharing (VSS) was introduced in order to solve information security issues. It is a modern cryptographic technique. It involves breaking up a secret image into $n$ secured components known as shares.

Mathematics, 2020 A ( k , n ) threshold secret image sharing (SIS) method is proposed to divide a secret image into n shadows. The beauty of this scheme is that one can only reconstruct a secret image with k or more than k shadows, but one cannot obtain any ...

Lossless and Efficient Secret Image Sharing Based on Matrix Theory Modulo 256
Mathematics, 2020 Most of today’s secret image sharing (SIS) schemes are based on Shamir’s polynomial-based secret sharing (SS), which cannot recover pixels larger than 250. Many exiting methods of lossless recovery are not perfect, because several problems arise, such as

A contrast-sensitive reversible visible image watermarking technique [PDF]
, 2009 A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

Nearly Optimal Deterministic Algorithm for Sparse Walsh-Hadamard Transform [PDF]
, 2015 For every fixed constant $\alpha > 0$, we design an algorithm for computing the $k$-sparse Walsh-Hadamard transform of an $N$-dimensional vector $x \in \mathbb{R}^N$ in time $k^{1+\alpha} (\log N)^{O(1)}$.
