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

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

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
