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.

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 ...
