Meaningful Secret Image Sharing with Uniform Image Quality
Mathematics, 2022 In meaningful secret image sharing (MSIS), a secret image is divided into n shadows. Each shadow is meaningful and similar to the corresponding cover image.

Using Two Meaningful Shadows to Share Secret Messages with Reversibility [PDF]
Symmetry, 2019 A subtopic of visual secret sharing (VSS) is information hiding-based VSS (IH-VSS), which embeds secret messages into images using an information hiding technique. In the IH-VSS scheme, stego-images are divided into shadows under the guidance and constraint of some predetermined approaches.

General Meaningful Shadow Construction in Secret Image Sharing
IEEE Access, 2018 Secret image sharing (SIS) is an important technique for image protection. Several shadows are produced in SIS through scrambling pixel values and their correlations of a secret image.

Support in the Shadows: Findings From a Qualitative Study Exploring Fathers’ and Non‐Birthing Partners’ Perceptions and Experiences of Support During a Termination for Medical Reasons [PDF]
Health ExpectationsBackground Termination for medical reasons (TFMR) is an essential aspect of reproductive healthcare. While physical and emotional care of the birthing parent is central within healthcare systems, less is known about the experiences and support needs of ...

Sharing a Large Secret Image Using Meaningful Shadows Based on VQ and Inpainting [PDF]
KSII Transactions on Internet and Information Systems, 2015 This paper proposes a novel progressive secret image-hiding scheme based on the inpainting technique, the vector quantization technique (VQ) and the exploiting modification direction (EMD) technique. The proposed scheme first divides the secret image into non-overlapping blocks and categorizes the blocks into two groups: complex and smooth.

XOR-ed visual secret sharing scheme with robust and meaningful shadows based on QR codes [PDF]
Multimedia Tools and Applications, 2019 AbstractQuick response (QR) codes are becoming increasingly popular in various areas of life due to the advantages of the error correction capacity, the ability to be scanned quickly and the capacity to contain meaningful content. The distribution of dark and light modules of a QR code looks random, but the content of a code can be decoded by a ...

Progressive secret image sharing scheme using meaningful shadows
Security and Communication Networks, 2016 AbstractThis paper proposes a novel secret image sharing scheme, which progressively hides a secret image into multiple different meaningful cover (or host) images by utilizing a magic matrix. The produced shadows are high visual quality, meaningful images that differ from each other.

A reversible and lossless secret image sharing scheme with authentication for color images
Journal of King Saud University: Computer and Information Sciences, 2023 With the increasing concern for public privacy protection, Secret Image Sharing (SIS) has garnered significant attention among researchers. The goal of SIS is to split a secret image into multiple shadows, rendering it unrecoverable unless a specific ...

AMBTC-based visual secret sharing with different meaningful shadows
Mathematical Biosciences and Engineering, 2021 Secret sharing based on Absolute Moment Block Truncation Coding (AMBTC) has been widely studied. However, the management of stego images is inconvenient as they seem indistinguishable. Moreover, there exists a problem of pixel expansion, which requires more storage space and higher transmission bandwidth. To conveniently manage the stego images, we use
