A New Scheme for Lossless Meaningful Visual Secret Sharing by using XOR Properties [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2023
In this paper, a novel scheme for lossless meaningful visual secret sharing using XOR properties is presented. In the first step, genetic algorithm with an appropriate proposed objective function created noisy share images.

A contrast-sensitive reversible visible image watermarking technique [PDF]

open access: yes, 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 ...

A secure lossless recovery for medical images based on image encoding and data self-embedding [PDF]

open access: yesCluster Computing, 2021
To protect the security of data outsourced to the cloud, the tampers detection and recovery for outsourced image have aroused the concern of people. A secure tampering detection and lossless recovery for medical images (MI) using permutation ordered binary (POB) number system is proposed.

Reversible watermarking scheme with image-independent embedding capacity [PDF]

open access: yes, 2005
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

Lossless $(k,n)$ -Threshold Image Secret Sharing Based on the Chinese Remainder Theorem Without Auxiliary Encryption

open access: yesIEEE Access, 2019
A typical Chinese remainder theorem (CRT)-based secret sharing (SS) scheme has been proposed by Asmuth and Bloom for several decades, with lower computation complexity compared to Shamir's original polynomial-based SS.

Lossless Snubber Cell for a Soft-Switched Bidirectional Buck–Boost Converter

open access: yesIEEE Access, 2020
In this paper, we propose a lossless snubber cell for a soft-switched bidirectional buck-boost converter (BBC). The proposed snubber cell provides all switches with soft-switching conditions in both the bidirectional power flows of the BBC.

Adaptive Unified Data Embedding and Scrambling for Three-Dimensional Mesh Models

open access: yesIEEE Access, 2019
Traditionally, unified data embedding and scrambling techniques have been designed for grayscale images, which cannot be applied directly to a three-dimensional (3D) mesh. Recently, the universal use of 3D technology inspired us to innovate in this field.

Practical Secret Image Sharing Based on the Chinese Remainder Theorem

open access: yesMathematics, 2022
Compared with Shamir’s original secret image sharing (SIS), the Chinese-remainder-theorem-based SIS (CRTSIS) generally has the advantages of a lower computation complexity, lossless recovery and no auxiliary encryption. However, general CRTSIS is neither

A Novel Robust Reversible Watermarking Scheme for Protecting Authenticity and Integrity of Medical Images

open access: yesIEEE Access, 2019
It is of great importance in telemedicine to protect authenticity and integrity of medical images. They are mainly addressed by two technologies, which are region of interest (ROI) lossless watermarking and reversible watermarking.
