A Lossless-Recovery Secret Distribution Scheme Based on QR Codes [PDF]
Entropy, 2023 The visual cryptography scheme (VCS) distributes a secret to several images that can enhance the secure transmission of that secret. Quick response (QR) codes are widespread. VCS can be used to improve their secure transmission.

Tamper localization and lossless recovery watermarking scheme with ROI segmentation and multilevel authentication. [PDF]
J Digit Imaging, 2013 Tamper localization and recovery watermarking scheme can be used to detect manipulation and recover tampered images. In this paper, a tamper localization and lossless recovery scheme that used region of interest (ROI) segmentation and multilevel authentication was proposed. The watermarked images had a high average peak signal-to-noise ratio of 48.7 dB

Weighted Polynomial-Based Secret Image Sharing Scheme with Lossless Recovery [PDF]
Security and Communication Networks, 2021 In some particular scenes, the shadows need to be given different weights to represent the participants’ status or importance. And during the reconstruction, participants with different weights obtain various quality reconstructed images.

Weighted visual secret sharing with multiple decryptions and lossless recovery.
Mathematical Biosciences and Engineering, 2019 Traditional visual secret sharing (VSS) encodes the original secret image into n shares, and each share is of equal importance. However, in some scenarios, we need to make a difference between the participants according to the levels of their importance.

An Enhance Scheme of Visual Secret Share for Lossless Recovery
International Journal of Engineering and Advanced Technology, 2020 Algorithms in Visual Cryptography usually uses a sharing scheme where instead of sharing the secret or message directly, it is embedded into multiple shares which are then shared between the intended individuals whereby upon receiving them the decrypting
